NOTE
ADJUSTING YOUR KIT
1. Align the assembly vertically and horizontally (Fig. 7). There must be sufficient clearance
between the air springs, the frame, and the tire and brake drum at the maximum inflated
diameter (7.0”). Tighten the upper bracket and mounting bolts for the bellows to 20 lb.-ft.
2. On some vehicles the outer flange of the axle jounce bumper bracket extends out from the
frame rail. Trim the outer flange of the bracket or remove the bracket assembly entirely to
provide sufficient clearance from bellows to the frame for the maximum inflated diamter
(7.0”).
3. Position the upper bracket so that it is parallel with the lower bracket.
The kit mounts so that it follows the angle of the leaf springs.
4. Align the assembly vertically and horizontally. The distances between points X and Y
(Figs. 6 and 7) should be approximately equal, between 5 and 7 at normal ride height.
5. Adjust the upper bracket so that at least four bolt holes (two on each side) will be on a flat
section of the frame rail. Use the widest bolt spacing PSIle. Do not drill on the radiused
edges of the frame. Clamp the upper bracket to the frame rail with a C-clamp or welding
clamp. Before marking any holes, check the following:
a. Are four holes in the upper bracket positioned on flat section of the frame rail?
b. Are the upper and lower brackets aligned vertically with each other?
c. Are the distances between points X and points Y equal?
d. Is the distance between the upper and lower brackets between 5” and 7”?
