Trail Master Suspension recommends a certified technician install this system . In addition to these instruction , professional knowledge of disassemble/reassembly procedures as well as post instructions checks must be known. Attempts to install this system without this knowledge and expertise may jeopardize the integrity and/or operating of the vehicle. Please read all the instructions before beginning the installation. Check the kit hardware against the parts list. Be sure you have all the needed parts and understand where they go. If anything is missing , do not proceed with the installation, call Trail Master Suspension to obtain needed items.

As a general rule, the taller a vehicle is the easier it will roll. We strongly recommend , because of rollover possibility, that seat belts and shoulder harness be worn at all times. Avoid situations where a side rollover may occur. Braking performance and capabilities are decreased when signifi
cantly large/heavier tires and wheels are used. Take this into consideration while driving, also , speedometer recalibration is necessary when larger tires are installed. Do no add, alter, or fabricate any factory or after-market parts which increase vehicle height over the intended height of the Trail Master Suspension product purchased. Mixing with suspension lift voids all warranties. Trail Master Suspension makes no claims regarding lift-
ing devices and excludes any and all implied claims. We will not be responsible for any products that are altered. The only exception to the above policy is combining a Trail Master Suspension torsion key leveling kit with a Performance Accessories body lift system .

Installation steps
1. Place the vehicle on a level surface. Prior to beginning, record ride height on each side of the vehicle by measuring from the center of the spindle to a consistent point on the wheel well. Record these measurements for future reference.
2. Put the transmission in Park or 1st gear (manual transmissions) and chock the rear tires.
3. Raise the front of the vehicle using a jack. Raise it enough to completely unload the front suspension. Place a jack stand under each frame rail just behind the lower control arms for the front suspension. Ease the frame down on to the stands, but leave a slight load on the jack as a safety precaution.
4. Verify the front tires are off the ground and that the suspension is unloaded, or at full extension travel.
5. Locate the torsion bar crossmember. There is a bolt on each side of the crossmember that adjusts torsion bar preload. Measure or mark the exposed length of the adjuster bolt for reference during re-assembly. See Figure 1.
6. Position the appropriate torsion bar puller tool on the crossmember. Be sure the top of the puller tool engages the recess present in most crossmembers. Also be sure the lower end of the puller tool engages a recess on the torsion key near the adjuster bolt. See Figure 2.
