Read And Understand All Instructions And Warnings Prior To Installation Of
System And Operation Of Vehicle.
THANK YOU
Your truck is about to be fitted with the best suspension system on the market
today. That means you will be driving the baddest looking truck in the
neighborhood, and you’ll have the warranty to ensure that it stays that way
for years to come. Thank you for choosing BDS Suspension!
BEFORE YOU START
BDS Suspension Co. recommends this system be installed by a professional
technician. In addition to these instructions, professional knowledge of
disassembly/ reassembly procedures and post installation checks must be known.
FOR YOUR SAFETY
Certain BDS Suspension products are intended to improve off-road performance.
Modifying your vehicle for off-road use may result in the vehicle handling
differently than a factory equipped vehicle. Extreme care must be used to
prevent loss of control or vehicle rollover. Failure to drive your modified
vehicle safely may result in serious injury or death. BDS Suspension Co. does
not recommend the combined use of suspension lifts, body lifts, or other
lifting devices. You should never operate your modified vehicle under the
influence of alcohol or drugs. Always drive your modified vehicle at reduced
speeds to ensure your ability to control your vehicle under all driving
conditions. Always wear your seat belt.
BEFORE INSTALLATION
- Special literature required: OE Service Manual for model/year of vehicle. Refer to manual for proper disassembly/reassembly procedures of OE and related components.
- Adhere to recommendations when replacement fasteners, retainers and keepers are called out in the OE manual.
- Larger rim and tire combinations may increase leverage on suspension, steering, and related components. When selecting combinations larger than OE, consider the additional stress you could be inducing on the OE and related components.
- Post suspension system vehicles may experience drive line vibrations. Angles may require tuning, slider on shaft may require replacement, shafts may need to be lengthened or trued, and U-joints may need to be replaced.
- Secure and properly block vehicle prior to installation of BDS Suspension components. Always wear safety glasses when using power tools.
- If installation is to be performed without a hoist, BDS Suspension Co. recommends rear alterations first.
- Due to payload options and initial ride height variances, the amount of lift is a base figure. Final ride height dimensions may vary in accordance to original vehicle attitude. Always measure the attitude prior to beginning installation.
Visit 560plus.com for more information.
BEFORE YOU DRIVE
Check all fasteners for proper torque. Check to ensure for adequate clearance
between all rotating, mobile, fixed, and heated members. Verify clearance
between exhaust and brake lines, fuel lines, fuel tank, floor boards and
wiring harness. Check steering gear for clearance. Test and inspect brake
system.
Perform steering sweep to ensure front brake hoses have adequate slack and do
not contact any rotating, mobile or heated members. Inspect rear brake hoses
at full extension for adequate slack. Failure to perform hose check/
replacement may result in component failure. Longer replacement hoses, if
needed can be purchased from a local parts supplier.
Perform head light check and adjustment.
Re-torque all fasteners after 500 miles. Always inspect fasteners and
components during routine servicing.

TROUBLESHOOTING INFORMATION FOR YOUR VEHICLE
- Do not put a spacer on top of the coil to get more than 8-inches of lift. You will have driveline and driveability issues.
- If using this kit with an adjustable front track bar, it MUST be set to factory length. Under full compression the trackbar bracket clears the coil bucket by a small amount. Any variation from the factory length will cause contact.
- If you have a mega cab model or quad cab long bed, you will need the carrier bearing drop kit (available separately).
- If you ever need to buy a replacement transmission output seal. The transmission seal you need is from a 48RE transmission. This was found in all automatic transmissions behind the 4wd 5.9 Cummins 03-07. Federal Mogul part# 710058. It has an outside diameter of 2.563”. Kits built after 9-10-2010 (R or M code 09121 0) (month day year) will include the seal.
- Manual transmission models require T-case indexing ring kit 122802 instead of 122801. Additional front driveshaft clearance at the transmission cross member may be needed on manual transmission models with the indexing ring installed.
- A step drill is highly recommended. 11 /16″ holes are required to be drilled in the installation.
- If installing optional coilover kit, welding is required, disconnect the battery before you start!
- 03-08 model year trucks require sway bar relocation brackets at the axle for steering clearance. They are included in the kit. 09+ model years have a different style steering that requires no axle bracket relocation.
INSTALLATION INSTRUCTIONS
SPECIAL TOOLS
Pitman arm puller
Depending on model year kit: Cutoff tools, transmission jack, welder,
grinder
-
Park vehicle on clean flat and level surface.
-
Block the wheels for safety.
-
Measure and record the distance from the center of the hub to the bottom of the fender lip. Record below:

Right Front ____ Right Rear ____ -
These instructions cover a complete BDS lift kit installation. If installing a long arm upgrade kit, follow steps 6-14 for the bracket installation and steps 19-24 for the long arm installation. For final control arm torque specifications see the end of the instruction sheet.
-
Disconnect the front trackbar from the frame. Retain hardware. Do this when the vehicle is on the ground. It may be necessary to have an assistant shake the steering wheel back and forth to get the bolt to remove more easily. (Fig 1 a)
8″ KITS ONLY -TRANSFER CASE INDEXING RING
See separate instruction sheet for indexing ring installation.
6″ AND 8″ LONG ARM BRACKET INSTALLATION (BOLT PACK# 782): -
Support the transmission cross member with a jack.
-
Remove the 4 bolts that hold the transmission crossmember into position (Fig 6a).
-
Remove the 4 bolts that attach the front driveshaft to the transfer case. (Fig 7a, 7b)
-
Remove transfer case skid plate if equipped. It will not be reinstalled.
-
Install long arm bracket to the side of the frame rail around the transmission crossmember mount. Loosely attach with 9/16″ x 7″ bolts. Mark the top center holes to be drilled. Bolt pack# 782 (Fig 14a, 14b)
-
Remove the bracket and drill/ clearance holes to 11 /16”. A step drill is highly recommended.
-
Install rivet nuts with serrated edge washer as shown (Fig 1 Sa, 1 Sb, 1 Sc – shows collapsed rivet nut as a reference). The½” bolt goes thru the 5/8″ nut with a serrated edge washer that will bite into the rivet nut to keep it from spinning. Tighten until the backside of the rivet nut has been deformed INSIDE THE FRAME RAIL and is set into place (rivet nut will lock itself in place).
Note: See the end of this instruction sheet for detailed rivet nut installation procedures. -
Reinstall brackets with 9/16″ x 7″ bolts through the bracket and transmission cross member. Attach to rivet nuts with ½”x 1-1 /2″ bolts with thread locker on threads, use a spacer washer at the 3 locations on outside of the frame rail. Tighten½” hardware to 60 ft-lbs and 9/16″ hardware to 95 ft-lbs. (Fig 16)
-
Repeat for opposite side.
-

-
Disconnect the brakeline bracket from the axle. Retain bolt.
-
Support the front axle. Disconnect the front shocks
-
Lower the front axle and remove the front coils.
-
Grease and install bushings and sleeves into new longer shocks. Install the shocks with OE bolt in the lower mount, and new cup washers and bushings in the upper mount. Thread the upper nut on to get full engagement. The shocks will be removed and reinstalled later. The shocks are designed to carry the weight of the front axle and will allow the axle to move easily to remove and install the control arms.
-
With the axle well supported, remove the upper and lower control arms from the vehicle.
-
Grease and install the bushings and sleeves into the lower longer control arms. *note 2003-2009 models require 16mm ID sleeves, 201o models require 18mm ID sleeves in the axle end of the lower control arm. Install the grease zerks into control arms. All grease fittings are 90 degree fittings, rotate so they will be accessible once installed. (DRV Upper arm shown – Fig 17 & 18)
-
Install the upper control arms into the vehicle. Use new 14mm x 100mm bolts for the upper arms at both the bracket and axle. The upper arm will have a clearance bend to clear the tire when the wheel is turned. Run the bolts from outside to inside the vehicle. The Driver’s Arm will have a groove machined on the OD of the end that will go in the frame bracket. The main tube will be offset to the bottom side of the arm to give clearance to the body mount.
-
Use the factory cam bolt at the axle for the lower control arms. Attach the lower control arm to the relocation bracket with ¾”x 5″ hardware.
-
Do not tighten the control arm hardware at this time. It will be done with the vehicle set at ride height.
TRACKBAR / PITMAN ARM INSTRUCTIONS (BOLT PACK# 609 / 642): -
Mark the orientation of the pitman arm. Remove the pitman arm with appropriate tool.
-
Transfer mark over to the new pitman arm and reinstall with factory hardware. Tighten nut 150 ft-lbs.

-
Tighten 9/16″ hardware to 95 ft-lbs, 5/8″ hardware to 120 ft-lbs.
-
Do not install the trackbar into this bracket at this time.
BUMP STOP INSTRUCTIONS (BOLT PACK# 784): -
Remove factory bumpstops. It is easiest to take a hammer and hit the bumpstop sideways in order to get them to pop out of the cups, or use a set of channel locks. (Fig 21)
-
Locate the center of the two circular recesses in the cup. Mark the centers and drill out to 5/16″~21 /64”. Install the 3/8″ x 1-1 /4″ self threading bolts to cut threads into the frame. Remove the bolts after the threads are cut. BP# 784 (Fig 22)
-
Install the new urethane bumpstop into the bumpstop brackets with 3/8″flat washer, lock washer, and nut. Tighten nut securely. Bolt pack #784
-
Install the bumpstop assembly onto the frame with new 3/8″x 2″ bolts and washers with thread locker on the threads. Tighten to 35 ft-lbs.(Fig 23) SWAY BAR LINK INSTRUCTIONS (SEE SPECIFIC YEAR RANGE INSTRUCTIONS):
2009-2012 MODELS WITH SOLID TIE ROD (T-LINK STEERING SETUP): -
Grease and install 5B35 bushings (longer hour glass bushings with¾” ID) into one end of the sway bar link with 54587 sleeve (3/4″x 9/16″ ID x 1.575). Grease and install 5B58 (shorter bushings with 5/8″ ID bushing) into the other end with 45313 sleeve (5/8″x 10mm ID x 1-3/8″ long).

-
Install the sway bar link with the small bushings into the stem eliminator bracket with 3/8″ hardware.
-
Attach the other end of the sway bar link to the axle with 9/16″ hardware. Run the bolts from inside to the outside of the vehicle. (Fig 24) It may be necessary to slightly clearance the holes to accept the 9/16″ hardware. 09 and newer models will have left over hardware from bolt pack#783.| 03-08 MODEL YEAR TRUCKS (Y-LINK STEERING):
Tip
Models with y-link steering (03-08 models that have the drag link go from the pitman arm to the passenger’s side
steering knuckle). This steering does not provide enough clearance to the sway bar mounts, they must be modified. If you have an 03-08 model with the new T-link setup, installation of the brackets is still required due to the length of the sway bar links. -
Disconnect the tie rod end from one of the steering knuckles and swing the whole assembly out of the way. (Fig 25)
-
Disconnect the trackbar from the axle. Retain nut tab.
-
Cut the welds on both sides of the sway bar link mount at the axle. Remove the brackets from the vehicle.
-
Clean the area with a flap wheel or grinding wheel.
-
Place the sway bar mounting bracket against the axle as shown. The passenger’s side will use the factory trackbar hole. Mark and drill the other hole to ½” ~ 17 /32”.
-
Attach the bracket to the axle with the trackbar in position with new trackbar bolt and washer (14mm 03-07 / 16mm 08+) with factory nut tab, and½” bolt (with thread locker), with washer on the outside and square nut on the inside. The square nut will rest against the inside gussets of the axle and eliminate the need for a wrench. Tighten the½” hardware to 65 ft-lbs. Do not tighten the trackbar mounting bolt at this time. (Fig 26)
-
Repeat installation for drivers side. Align the bracket with the existing hole. Mark the opposite hole and drill both holes to ½”~17/32”.Reinstall the bracket with½” bolts (with thread locker) with washers on the outside and square nuts on the inside of the bracket. Tighten to 65 ft-lbs. (Fig 27)
-

-
Attach stem eliminator bracket to the sway bar with 5/8″ nylock nut with washer. Make the brackets parallel to the axle. Tighten securely.
-
Install the sway bar link with the small bushings into the stem eliminator bracket with 3/8″ hardware.
-
Attach the other end of the sway bar link to the new axle bracket with 9/16″ hardware. Run the bolts from inside to the outside of the vehicle. (See above Fig 24)
Tip
Depending on model year, there will be either an extra 74mm or 76mm bolt leftover from bolt pack #783.
COIL/ SHOCK INSTALLATION:
Tip
If installing optional coilovers, see separate instruction sheet for bracket installation – welding is required, don’t forget to disconnect the battery. -
Lower the front axle enough to install the coils. Use care not to overextend the factory brakelines or ABS wires.

BUMPER SPACER & PINCH WELD MODIFICATION FOR 38″TIRES (BOLT PACK# 812) -
Disconnect the fog light wiring harness (if equipped).
-
Remove the 6 bolts (3 per side) that attach the bumper to the frame horns. Later model trucks (2010-2012) may have 4 bolts per side, the top inside one is next to impossible to access, we do not provide replacement hardware for this position. Installing 3 bolts per side will be the same as early model (03-09) model year trucks.
-
Knock out the carriage bolts from the bumper.
-
Install new carriage bolts with retaining clips on the outer 2 positions. Install carriage bolt into the center positions without a retaining clip.(Fig 34a, 34b)
-
Install bumper onto vehicle with spacers over the carriage bolts. There are 2 bolts that will need to have a ¾”washer added under the head. These bolts only go through one layer of the bumper. The rest of the bolts do not need a washer under the head of the carriage bolt.
-
Adjust bumper so that it sits even.
-
Tighten½” carriage bolts to 55 ft-lbs.
-
Reconnect the fog light wiring harness.
-
The front plastic inner fender well needs to be removed. Bend over the pinch weld and trim 4 inches from the bottom of the foam insulation.

Drill hole to appropriate size for rivet nut installation. 1/2″ Rivnuts require an 11/16″ hole and 3/8″ Rivnuts require a 17/32″ drill. It is critical that this hole is drilled to the correct size. Remove any burrs that could keep the rivet nut from seating flat against either side of the hole surface.
Tip
If the correct drill size is not available, it is possible to drill the hole to an available smaller size and slowly grind it out to until the rivet nut fits tight.
RIVET NUT INSTALLATION TOOL ASSEMBLY -
For a 3/8″ rivet nut, place the provided 3/8″ SAE flat washer on the 3/8″ x 1-1 /2″ bolt, followed by 7 /16″ hex nut and then a 3/8″ serrated washer. Thread this tool assembly into the rivet nut.
-
For a 1/2″ rivet nut, place the provided 1/2″SAE washer on a 1/2″bolt followed by a 5/8″ nut and 1/2″ serrated edge lock washer. Thread this tool assembly into the rivet nut.
RIVET NUT INSTALLATION -
Place the installation tool with the rivet nut threaded on the end into the appropriately sized hole.
-
For a 3/8″ rivet nut, hold the nut closest to the rivet nut still with an 5/8″wrench and tighten the 3/8″ bolt with a 9/16 wrench to set the rivet nut. Be sure to hold the rivet nut flush to the surface and square to the hole as it is tightened. (Fig 1)
Tip
If available, an impact gun is recommended for tightening the bolt to ensure the rivet nut remains square to the hole and to ease holding the nut from spinning. -
For a 1/2″ rivet nut, hold the nut closest to the rivet nut still with a wrench and tighten the 1/2″ bolt with a 3/4″ wrench or impact gun to set the rivet nut. Be sure to hold the rivet nut flush to the surface and square to the hole as it is tightened. (Fig 2) TORQUE SPECIFICATIONS
-
3/8″ rivet nuts will approach 40 ft. lbs for maximum grip strength. Do not exceed 45 ft-lbs when setting the rivet nut.
-
1/2″ rivet nuts will approach 90 ft lbs for maximum grip strength. Do not exceed 100 ft-lbs when setting the rivet nut.
Tip
If using the recommended impact gun, use caution to not exceed the recommended torque specifications.
RIVET NUT TOOL REMOVAL -
Once the center bolt is tightened, remain holding the nut from spinning with the wrench and loosen the center bolt to remove the installation tool.
Caution It is very important to hold the nut as the bolt is loosened because the grip of the star washer will try to spin the rivet nut and ruin the installation. -
Verify proper installation by checking for consistent rivet nut deformation to see the threads are square and centered to the rivet nut.
