INSTRUCTIONS
1. Remove your stock rear sway bar.
2. Jack up the rear of the car and place jack stands under rear end housing. Let jack
down so the weight of the car is on the rear housing. This will place the rear
suspension at ride height. (Note: Place jack stands in the area of the LCA mounts so
they do not interfere with sway bar installation.)
3. It’s time to prepare the sway bar for installation. Note that when orientating the
sway bar, the center bend faces down. Remove the poly bushings from their shell.
Using the supplied grease packs apply silicone grease liberally to the inside of both
sway bar bushings. Install the poly bushings onto each end of the sway bar, and re-
install the bushing shells.
4. From here on out, this is a two person job as the amount of things that need to be
done exceed two hands, not to mention the weight of the bar! Place a u-bolt on one
end of the rear housing. Now slide a spacer saddle over the u-bolt and hold it in
place. The second person can now hold the sway bar in position. Slide the bushing
shell onto the u-bolt. Install the flat washers and then the lock nuts, only make hand
tight at this time (start them as far as you can by hand). Now you can let this end
hang down until it rests on the u-bolt. Repeat the same procedure on the other end
of the sway bar.
5. Tighten all four of the u-bolt lock nuts until you have them barely snug, do not
fully tighten. Now you want to make sure the sway bar is centered on the rear side
to side, and front to back. Position the sway bar side to side until you have the same
distance from the outside of the bar to the shock on both ends. Position the bar front
to back so that the bar runs along the center line of the bottom of the axle tubes.
6. The rod ended end links have already been set at the proper length, do not
change the length. Keep the end link mounted to the sway bar as shipped.
