1. Lubricate the D-bushings and place them onto the straight areas of the bar on each side of the center hump
as shown in the photos.

2. Position sway bar on axle as shown in photos and locate the position on the axle tubes to mount the u­bolts. Be sure to put the U-Bolts Under Any Brake Lines, Wires or Hoses on the Axle to Avoid Any

Possible Damage.

3. Place saddle brackets onto the U-Bolts on the axle tubes. Place the U-Plates over the D shaped bushings on
the bar and attach the sway bar to the U-Bolts and saddle brackets with the flat washers and locknuts pro­vided. LEAVE LOOSE AT THIS TIME to allow for adjustment later.

4. Assemble end links by installing the hourglass bushing and then the spacer into the loop of the end link.

Lubricate bushing and spacer before assembly.

5. Assemble bushings, washers and nuts on end link as shown in photos. The lock nut is installed on the bot­tom of the end link bushing assembly. Adjust jam nut and hex nut on upper portion of end link to raise or
lower assembly to align arms of sway bar to be as parallel with ground as possible.

6. Tighten lock nut on bottom of end link until bushings begin to bulge slightly. Tighten jam nut against up­per hex nut to lock adjustment.

7. Align end links for best fit as shown in photos so that end links are perpendicular to the sway bar and the
arms of the sway bar are parallel with the ground. .When satisfied with the location and alignment of the
end links, mark location of holes for the end links on frame rail.

8. Drill a 17/32 (.531) hole in the frame at marked locations. BEFORE DRILLING ANY HOLES IN THE

RAIL—RELOCATE AND/OR PROTECT FUEL TANK AND ANY WIRES, FUEL, OR BRAKE
LINES THAT MAY INTERFERE WITH THE DRILL BIT OR SWAY BAR INSTALLATION.

9. Attach end links to hole in frame rail using the 1/2” X 2-1/2” bolt, washers and 1/2” locknut. Install bolt
through end link with a flat washer mounted to the inside of the frame rail and the outside of the bushing.
Tighten to 60 ft-lb.

10. Adjust sway bar on axle so that there is at least 1/2” clearance between the bar and the axle. Ensure ade­quate clearance between the sway bar and all shock absorbers, brake lines, hoses, cables and electrical con­nections. When all clearances are confirmed, tighten U-bolts to 30-35 ft-lb. Double nut and tighten.

11. Bounce vehicle and check for clearance on all undercarriage components. Recheck installation, look for
clearance on gas lines, exhaust pipes, brake lines, wiring, etc.

12. Drive vehicle for a few miles, then recheck for position and tightness, readjust and retorque as needed.
Then recheck periodically thereafter.
