R-JOINT SPACER INSTALLATION
Install the Spacers by inserting the SMALL side of the SPACER into the Center Pivot Ball. Push them in until they bottom out and stop.

New R-Joints will be quite stiff (75-90 in/lbs breakaway torque) until they “break in” after a few miles of use. After the break in period they will move much more freely. Because the composite bearing race contains  self lubricating ingredients, no additional lubrication is needed or desired. Any additional lubrication will only serve to attract more dirt and debris to the R-Joint and actually shorten its life.

R-Joint & Upper Bar Installation

It is important to not get the bushings crooked on installation.
Start by removing the upper bars. Next, remove the upper axle housing bushings.

  1. Install the R-Joint Housing into the OEM bushing hole, making sure it goes in straight.

  2. Install the Spacers by inserting the SMALL side of the SPACER into the Center Pivot Ball.
    Push them in until they bottom out and stop.

  3. Install the R-Joint Spacers into the R-Joint End. Remove the OEM Upper Control Arms and replace them with the StrongArms.

  4. Install the Spacers by inserting the SMALL side of the SPACER into the Center Pivot Ball. Push them in until they bottom out and stop.

  5. Attach to front on the lower StrongArm to the frame using the ½” x 3 ½” bolts, fl at washers and nylok nuts supplied.

  6. Attach to rear of the lower StrongArm to the frame using the ½” x 3 ½” bolts, fl at washers and nylok nuts supplied.

Shock Installation

The Rear Shocks will be installed in conjunction with the Rear CoilSprings.

  1. With the OEM Shock removed, install the Ridetech shock. Attach the Top of the Shock in the OEM Location using the OEM Hardware.
    It may be necessary to rotate the Trunnion to get it in the correct position. This can be done by sticking a screwdriver in one of the slots and spinning the trunnion in the shock bushing.

Shock adjustment 101- Single Adjustable

Rebound Adjustment:
How to adjust your new shocks
The rebound adjustment knob is located on the top of the shock absorber protruding from the eyelet or stud top.
You must first begin at the ZERO setting, then set the shock to a street setting of 12 or handling setting of 8.

  • Begin with the shocks adjusted to the ZERO rebound position (full stiff). Do this by rotating the rebound adjuster knob clockwise until it stops.
  • Now turn the rebound adjuster knob counter clockwise 12 clicks. This sets the shock at 12 for a street setting. If you are after a handling setting only go 8 clicks.

Take the vehicle for a test drive.

  • if you are satisfi ed with the ride quality, do not do anything, you are set!
  • if the vehicle is too soft increase the damping effect by rotating the rebound knob clockwise 3 additional clicks.
  • If the vehicle is too stiff rotate the rebound adjustment knob counter clock wise 2 clicks and you are set!

Take the vehicle for another test drive and repeat the above steps until the ride quality is satisfactory.
Note:
One end of the vehicle will likely reach the desired setting before the other end. If this happens stop adjusting the satisfied end and keep adjusting the unsatisfied end until the overall ride quality is satisfactory.
