SAFETY: BEFORE BEGINNING INSTALLATION BE SURE TO SET THE PARKING BRAKE AND
CHOCK THE WHEELS.
NOTE: TO EASE INSTALLATION AND PROPERLY ADJUST THE BAR, THE WEIGHT OF THE VEHICLE MUST BE ON THE SUSPENSION AS IF DRIVING DOWN THE ROAD. DO NOT RAISE THE VEHICLE BY THE FRAME.
NOTE: THIS KIT REQUIRES DRILLING THE FRAME RAIL AND POSSIBLE RELOCATION OF FUEL
AND BRAKE LINES. INSTALLER MUST ENSURE THAT THE SWAY BAR KIT WILL NOT INTERFERE WITH ANY FUEL OR BRAKE LINES OR HOSES.
IMPORTANT NOTE: SWAY BAR END LINKS MUST BEATTACHED ON OUTER
HOLE PRIOR TO INITIAL USE. SEE PHOTO 12.
1. Lubricate the D shaped bushings and place them onto the straight areas of the bar on each side of the
center hump as close to the outside bend as possible.
2. Make sure to identify which frame type is on the vehicle. Two piece frames have a weld seam in the
center of the rail joining the two halves of the rail section. One piece frames will not have this weld.
There are two mounting options for each frame rail type depending on the service of the vehicle. It is
recommended that the severe service option beused in any high performance application.
3. Hold bar up to the axle and locate the position on the axle tubes to mount the u-bolts. Be sure to put the
U-Bolts Under Any Brake Lines, Wires or Hoses on the Axle to Avoid Any Possible Damage. The
threads of the U-Bolts will point down. See PHOTO 3.

Remove undercoating where
large washer contacts frame.
4. Place the 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 bar to the U-Bolts and saddle brackets with the flat washers and
nuts provided. LEAVE LOOSE AT THIS TIME to allow for adjustment later. See PHOTO 3.
5. Position sway bar on axle so that it clears all frame mounted components including fuel tanks, brake
lines, fuel lines, etc. Sway bar can be rotated back and forth on axle to maximize clearance.
6. Assemble end links by inserting hourglass bushings and then inner sleeves into end link loops.
Fully lubricate bushings and sleeves before installation.
7. Attach end links to the center hole of the sway bar as shown in photo 2 using a 7/16-20 X 2-3/4”
bolt and washers. Align end links for best fit as shown in PHOTO 2. IMPORTANT NOTE –
Center hole position is only for determining hole location. The end link must be moved to the
outer hole prior to initial use.
8. Due to the amount of variation in rail width on these cars, adjustment will be required to obtain best
end link alignment to the rail. Make sure to review the appropriate frame detail for your appli-
cation. On 1 pc frames the thick washer nearest the frame can be omitted or the large spacer can be
cut down as required to obtain best fit. On 2pc frames, it may be necessary to add a thick washer between the end link and spacer.
9. The end links should be located as shown in PHOTO 2 so that the arms of the sway bar are even
with the bottom of the frame. When satisfied with location of sway bar and end links, mark hole location for the end links on the frame.
10. Prepare to jack up vehicle by placing wheel chocks on the front wheels. After the rear of the vehicle has been raised, support frame on jack stands and remove rear wheels. Make sure end link
hole location has been marked before raising vehicle as hole location must be determined with
the full weight of the vehicle on the suspension.
11. Transfer hole location to outer edge of frame rail. A piece of card board can be used by marking the
location of the hole on the cardboard and transferring the location to the outer rail. Drawing a line
on the frame square to the frame rails will keep the hole location square. See PHOTOS 6,7,&8.
12. Review end link mounting detail and confirm fit before drilling holes. BEFORE DRILLING
ANY HOLES IN THE RAIL—RELOCATE AND/OR PROTECT ANY FUEL OR BRAKE
LINES THAT MAY INTERFERE WITH THE DRILL BIT OR SWAY BAR INSTALLATION.

Spacer tube must be
1/32” shorter than
edge of large washer.

13. Drill a 15/32 (.468) hole through BOTH walls of the frame. Make sure holes are square to one another when drilling holes. It is easiest to drill through the outer wall first and use a transfer punch to
mark location on inner wall of frame.
14. Drill an 11/16 (.688) hole through OUTER wall of frame ONLY. See photo 7. A step drill works
well for this application. Do not use a hole saw as the hole must be a close fit to the spacer tube.
15. Insert 7/16 X 7” bolt through driver’s side rail as shown in PHOTO 9 with head on inside of frame
rail . Insert 7/16 X 7” bolt in same manner through passenger side rail. Insert spacer tube from outside of rail and check fit. The spacer tube is extra long to allow for frame section variation in the 1pc
and 2pc frames. If spacer tube is not welded to the outer wall of the frame, it must be fitted to the vehicle as described in step 17.
16. For severe duty it is recommended that the spacer tube be welded to the outer frame wall. If the
spacer is to be welded, review severe service end link detail for your frame rail and skip to line 19.
IMPORTANT—If any welding is to be done, the installer must ensure that all haz-
ards (fuel, electrical, etc) are eliminated and that fuel tanks, fuel lines, brake lines,
wiring, etc. are not affected by the welding operation.
17. Review end link detail and install Large washer over spacer tube. Check that spacer tube is at least
1/32” below the surface of large washer. Failure to do this will result in insufficient preload and
noise. Cut, file or grind end of spacer tube to achieve proper length. SEE PHOTO 10.& 10a.
18. Remove bolt and spacer from inside of frame rail.
19. Attach end link to frame as shown in detail and PHOTO 11. Applications with welded spacer do not
require the washers on the outboard wall of the frame. Torque end link bolts to 35-40 ft-lb. Due to
the variation in frame rail section width between the 1pc and 2pc frames, the bolt for the frame attachment was made long enough to accommodate the widest frame section. The bolt threads can be
cut down if necessary to improve appearance of the installation.
20. Replace rear wheels and torque lug nuts to factory specification. Lower vehicle so that the full
weight of the vehicle is on the suspension.
21. Tighten axle u-bolts to 50 ft-lb.

Attach end link to
outer hole before
driving. DO NOT
use inner holes until
first driving vehicle

with end link in outer
position.
22. Bounce the vehicle checking for clearance on all under carriage components: fuel tank, shocks,
exhaust, differential, brake and fuel lines, etc. Test drive the vehicle and recheck all clearances
and the installation alignment. Adjust as needed. Re-check your installation after one week of driving and periodically on a regular basis.
23.The sway bar has three end link mounting holes. The end link MUST be
mounted on the outer hole for initial use. SEE PHOTO 12. For a firmer setting,
use the inner holes. You must use the outer mounting hole as shown in photo 12
until you are accustomed to the vehicles new handling characteristics. After driving vehicle, a firmer setting may be selected if desired. It is recommended that
the outer hole be used for street driving.
