1. Remove the factory installed rear anti-sway bar and all the mounting hardware.
2. Attach spacer block to axle in same location as factory installed bushings as shown in photo 2. Attach spacer
block with supplied M10X30 bolts installed in factory threaded holes in axle bracket. Torque bolts to 25 ft-lb.
3. As per the photos, lubricate and install the D-shaped poly bushings onto the bar in the same location as the factory installed bushings on the sway bar. Place the U-plates over the D-bushings and attach the bar to the spacer
using the 3/8 X 1-1/4 bolts, washers and locknuts as shown in photo 2. Leave loose at this time to allow for
adjustment later. Use supplied grease to lubricate D-bushings.
4. As per the diagrams, assemble the adjustable end links and attach together. Use supplied grease to lubricate the
hourglass bushings and sleeves before assembly. Install hourglass bushing into end link loop first and then the
sleeve. The 3/4” diameter sleeve is used at the top of the end links to attach to the frame bracket and hardware.
5. Attach the end links to frame brackets using the 1/2” bolts, thick washers, and lock nut as shown in photos.
Leave loose at this time to allow for adjustment later.
6. Attach end links to sway bar using the 7/16” bolts, thick washers and lock nuts.
7. Center the sway bar under the vehicle by moving the bar side to side. Adjust the end links so that the sway bar
is as level with the frame as possible. Tighten all mounting hardware to the specified rates.
8. The sway bar arms have three mounting holes. Mounting the sway bar on the outer hole is the nominal position.
For firmer settings, use the inner holes. We recommend starting with the outer mounting hole until you are accustomed to the vehicle’s new handling characteristics. Then select the mounting point that best fits your driving style
9. Bounce the vehicle checking for clearance on all undercarriage components. Readjust the bar as needed and
check on periodically on a regular basis thereafter.
