II. Assembling the Air Spring Unit
1. Install the air fitting (J) to the top of the air sleeve (A).
Tighten 1 and
1
/
2
turns (Figure 1).
2. Attach the lower bracket (C) to the bottom of the air sleeve
(A) using the small flat head screw (H). Tighten securely
(Figure 1).
3. Install the upper bracket (B) onto the top of the air sleeve,
being sure to insert the air fitting through the hole on the
bracket (Figure 1).
4. Install the nylon nut (I) and large star washer (K) to the top
of the upper bracket by feeding it through the fitting. Leave
loose at this time for later adjustment (Figure 1).
5. Repeat assembly for other sleeve.
III. Installing the Sleeve Assembly
1. Remove the tires. This kit should be mounted at normal
ride height recorded on page 2.
2. Set the assembly on the leaf spring, rearward of the axle.
The tab on the lower bracket should hook over the rearward
leaf spring U-Bolt (Figure 1).
3. Attach the lower bracket to the leaf spring using U-Bolt
Figure 2

(D) and clamp bar (E). Secure with flat washers (G) and lock nuts (L). Refer to Figure 1. Torque to 16
ft-lbs.
4. Ensure that there is at least
1
/
4
" clearance between the roll plate and the closest part of the frame (Figure 4). The
closer space will be rearward of the sleeve assembly.
5. Align the upper bracket so that it is parallel and perpendicular with the lower bracket (Figure 2).
NOTE: The upper bracket will be close to the jounce bumper bracket weld on the back side (Figure 3).
6. Using the upper bracket as a template, mark any one of the holes on the upper bracket except the
bottom rear hole (Figure 4).
7. Flip the air spring down away from the frame. Center punch the previously marked upper hole.
8. With the air spring still flipped down, drill the center punched hole location with a
5
/
16
" drill bit.
NOTE: It is only necessary to drill through the outside sections of the frame to install the self-tapping
hardware.
9. Attach the upper bracket to the frame with one self-tapping screw (F). See Figure 1.
Upper bracket will be close
to jounce bumper weld.
