7. Next you want to install the upper end link mounts. These get welded to the
underside of the frame channel. Clean the frame channel with a sander. Hold the end
link so it is running straight up and down and tack in place. Weld around the upper
end link mounts. Note that the crossmember has a contoured shape. Keep one end
of the end link mount flush to the crossmember, the other end that lays over the
contoured portion of the crossmember you will need to slug to bridge the gap and
then weld. The upper end link mount must be sitting straight across horizontally, do
not angle the mount.
8. With both end links installed and tightened, you can now fully tighten the lock
nuts on the u-bolts. Do not over tighten the u-bolts or the bar will not rotate
properly. You should be able to rotate the bar by hand with force.
9. Jack the car up and remove the jack stands, place vehicle back on the ground.
10. Now we’re going to adjust the sway bar and set it with the proper pre-load.
Place the jack under the front of the car, make sure the jack is perfectly centered on
the front crossmember. Jack the front of the car in the air until the front tires are
BARELY off of the ground, stop there.
11. Check your rear tire pressures and make sure you have the exact same
pressure in both rear tires. Set your rear tire pressure to whatever psi you run them
at when racing at the track.
12. Whoever will be driving this vehicle now needs to sit in the driver’s seat of the
car, shut the driver’s door. (Simulate driving the car).
13. Measure from the lower rear corner of both the driver’s and passenger’s side
door jam to the ground (car should be on a level surface, ie. cement). We’re looking
to have the driver’s side 1/16” lower then the passenger’s side.
14. Adjust the passenger’s side end link (by lengthening or shortening) until you
achieve the above setting. Tighten the jam nuts and re-check your dimensions. Once
you have the adjustment properly set, tighten all four jam nuts on both end links.
Note: We recommend using removable strength Loctite on the threads to keep the
jam nuts tight on a street driven car.
15. With this sway bar set up, if you were previously running an air bag in your
spring, remove it. You also want to run the same rear spring rate on both sides of
the car.
