NOTE
INSTALLING THE AIR SPRING KIT
Your vehicle may be equipped with a rear brake proportioning valve. Any type of load
assist product could affect brake performance. We recommend that you check with your
dealer before installing this type of product. If your vehicle DOES NOT have a rear brake
proportioning valve or is equipped with an anti-lock type brake system, installation of a load
assist product will have NO EFFECT on brake performance.
UNBOLT THE LOWER BRACKET FROM THE LEAF SPRING IF THE VEHICLE IS TO BE
SERVICED BY A FRAME CONTACT HOIST.
1. Remove the stock jounce bumper from under the frame (fig. 1).
Some late model jounce bumpers have alignment pins that will need to be removed (fig. 1).
Grind pins flush to the jounce bumper once removed.
2. Insert the J-bolts (K) through the upper bracket (B or C) with the curved part facing
inboard.
3. Attach the lower portion of the upper bracket (B or C) to the frame using the stock jounce
bumper. Secure in place with the supplied M10-1.25 x 45 bolt (F) or M10-1.50 x 45 bolt
(G) and M10 lock washer (H).
The upper brackets are left- and right-side specific, designated by a “L” and “R” label.
