1. As in Photos 1, 2 and illustration, install the sway bar. Lubricate the insides and place D-shaped poly-
urethane bushings on the sway bar, then position the bar over the top front of axle.
2. Install U-plates and U-bolts as shown. Be sure the U-bolts go under the brake lines and cannot crush it.
Leave loose at this point.
3. Install the end link per Photo 1 and illustration.
4. As shown in the illustration and Photo 1, place the 4 hole plate up into position. Assemble using 3/8”
cap screws on cross member and on 4 hole plate as shown. Be sure the two slot holes are under the
frame gusset plate for marking purposes.
5. Position the frame plate over the upper end link as if to install it on the end link. Align the end link ver-
tical in all directions and mark the frame gusset. Remove the plate, lower the sway bar arms out of the
way and drill two (2) 5/8” diameter holes in the gusset. Be careful there is no wiring, brake lines or fuel
lines that can be damaged by the drilling operation on the top sides of the frame gusset.
6. Complete the installation of the frame plate and end link by using two (2) 1/2” bolts, large flat washers
and 1/2” nut provided. Tighten all nuts securely and double nut when provided.
7. Align the end link in a vertical position by installing the axle components and sway bar on the axle.
Tighten the U-bolts to 100 ft-lbs and double nut. Again watch for clearance at brake lines, etc.
8. Bounce the vehicle and check for clearance on all undercarriage components. Be sure all nuts and bolts
are securely fastened and double nuts used where necessary or provided.
9. Recheck your installation, look for clearance between gas lines, exhaust pipes, brake lines, wiring, etc.
After one week of driving check your installation and periodically thereafter.
