Avoid Rollovers and Crushing Injuries
- Use care when turning:
Turning the steering wheel too far or too fast can result in a rollover or loss of control.
-Slow down before entering a turn.
-When making tight turns from a stop, or at slow speeds, avoid sudden or hard acceleration.
-Avoid sideways sliding, skidding, or fishtailing, and never do donuts. - Drive straight up and down inclines, not across them, if crossing a hill is unavoidable, drive slowly and turn downhill immediately if you feel the vehicle may tip.
Abrupt maneuvers or aggressive driving have caused rollovers- even on flat, open ares

Ensure the rear is raised high enough to accommodate the lift and larger
tires.
Remove the wheels and tires.
STEP 15 15mm SOCKET
Support the center of the rear axle using a floor jack and leave in place to
support motor weight during this leaf spring swap.
Loosen the U-bolt hardware on the passenger’s side of the axle but DO NOT
fully remove yet. This will keep the motor in place while the other side is
being swapped over.
STEP 16 15mm SOCKET
On the driver’s side of the axle, remove the nuts holding the U-bolts and the
bottom of the shock.
Remove and save the shock bracket as well as all hardware.

Once complete on both sides, tighten all U-bolt nuts to 35lb-ft (47Nm).
Attach new wheels and tires to the vehicle using aftermarket 1/2″ lug nuts.
Torque the lug nuts to 50-85lb-ft (70-115Nm)
Remove the jack stands and lower the vehicle to the ground. We recommend
installing 20″ tires with 3:4 wheel offset on this 4″ Lift Kit.
- Increasing tire size larger than the stock 18″ will increase the operating speed. Take care when maneuvering at all times.
- Do NOT use tire heights greater than 20″ tires on 4″ Lift Kit. Exceeding tire heights larger than recommended will cause unintended speeds and performance issues.
ALIGNMENT & CAMBER ADJUSTMENT
STEP 1 19mm & 21mm WRENCH
Once the rear lift is installed, set the alignment of the vehicle.
On flat, level ground, use a large framing square to check and adjust the
camber of each front wheel until the tire is perpendicular to the ground.
To adjust,
loosen the jam nuts (21mm wrench) on each side of upper a-arm turnbuckle. Use
a (19mm wrench) to turn the center of the turnbuckle in or out as needed.
Continually check the camber with the framing square as you turn the
turnbuckle.
Once properly adjusted, tighten each jam nut out against the upper a-arm with
a 21mm wrench (not against the center of the turnbuckle).
Repeat on the opposite side of the vehicle.![MADJAX 16-054 King Bolt Lift Kit

STEP 2 19mm and 12mm WRENCH
Ensure the steering wheel is straight to begin adjusting the toe of the front
tires. The measurement between the center of the tread of the two front tires
at the front side of the tire should be 1/8″-1/4″ shorter than the same
measurement at the back side of the tires.To adjust, loosen the jam nut on either side of each
steering rack. Turn the extension to adjust in or out as needed and recheck
the measurement front and back. Also, ensure that the measurement from the
front of each tire to the center of the vehicle is the same on both sides and
adjust accordingly.
Once the toe is corrected, tighten the jam nuts on both steering arms.Test
drive vehicle and check camber and toe measurements again. If needed, adjust
accordingly and retighten all hardware. Loosen and adjust steering wheel to be
straight if needed and re-tighten.
STEP 3
Place the included warning label in a highly visible area on the vehicle for
all users to read before operating the vehicle (recommend foot board as shown
or steering wheel).
Use the additional Warning Label provided to place in view of a well protected
area such as in the battery/ motor compartment.
IMPORTANT: These instructions should be kept and stored in this cart for future reference on how to adjust toe/camber, brakes, and re-grease of front lift components. Review installation instruction steps to ensure this MadJax lift kit was properly installed to the provided instructions.
