WARNINGS & DISCLAIMERS

By installing this product you acknowledge that the suspension of this vehicle has been modified. As a result, this vehicle may handle differently than that of factory-equipped vehicles. As with any vehicle, extreme care must be used to prevent loss of control or roll-over during sharp turns or abrupt maneuvers. Always wear seat belts, and drive safely, recognizing that reduced speeds and specialized driving techniques may be required. Failure to drive this vehicle safely may result in serious injury or death. Do not drive this vehicle unless you are familiar with its unique handling characteristics and are confident of your ability to maintain control under all driving conditions. Some modifications (and combinations of modifications) are not recommended and may not be permitted in your state. Consult your owner’s manual, the instructions accompanying this product, and state laws before undertaking these modifications. You are responsible for the legality and safety of the vehicle you modify using these components.

    • Note original ride height measurement from center of rear fender arch to ground.

    • Measure your lift block to determine the difference from stock (i.e. 1", 2", 3", 4", 5", 6")

    • Safely lift truck and support with jack stands under axle. Remove the rear wheels.

  1. Fully deflate air springs and disconnect air line from the air fitting. Remove the upper and lower air spring mounting hardware. Droop the suspension for easier removal of the assembly. You do not need to remove the lower air spring bolt if you are installing a 1" lift.

    • Remove the upper and lower air spring mounting hardware. Droop the suspension for easier removal of the assembly.

    • You do not need to remove the lower air spring bolt if you are installing a 1" lift.

    • Your upper and lower brackets may look different depending on the ReadyAIR Kit you have.

    • Un-bolt the two 3/8" bolts holding the upper bracket to the air spring.

    • Repeat for passenger side.

    • Unless installing a 1" lift, remove the one 3/8" bolt holding the lower bracket to the air spring and remove from vehicle.

    • Repeat for passenger side.

    • Reference the lift amount step in the following steps that matches your lift block amount and then follow the steps to Prepare your A, B and Final spacers accordingly.

  2. Bolt one lift spacer between the air spring and upper bracket using the "AIR SPRING" holes and supplied 1.75" long 3/8" bolts with flat washers. Apply some threadlocker to each bolt. Torque the 3/8" hardware to 15 FT. LB.

    • Torque the 3/8" hardware to 15 FT. LB.

    • Reconnect air line to the air fitting.

    • Repeat for passenger side.

    • Refer to Steps 13 & 14 for verifying fitment and Final Safety Checks.

  3. For 2-6 inch lifts, the lift spacers need to be prepped with hardware before assembling to the air spring. Place a 1/4"-20 nut in the two hex holes on the underside of the lift spacer that correspond to the holes marked "A" on top of the lift spacer. Make sure ALL nuts are oriented with the nylock portion of nut facing out, as shown, when they are inserted into the hex holes.
