1. Lay out the spring leaves into two (2) sets. The long end of the spring must be installed toward the rear of the
vehicle and the short end toward the front.
2. Place the spring on top of the main spring with the long end toward the rear of the vehicle.
3. Place the U-bolts with the straight legs in the cups at the ends of the spring with the silencer bushing between
the main spring and the helper spring as shown in the diagram. Loosely install the crossbars using the
hardware provided.
4. Adjust the crossbars on the end of the springs so that the adjacent leaf tip will not make contact with the
crossbar when the spring is deflected. It may be necessary to move the spring stack fore or aft for best
alignment.
5. Install 1/2”U-bolts next to the hat section as shown in the diagram. The U-bolt should be fastened as close to
the hat section as possible. If you are working on 2-1/2” wide springs position the outboard U-bolt leg against
the outboard edge of the main spring to maximize brake hose, caliper, and backing plate clearance. The U-
bolts may also be installed with the legs pointing up and crossbars on top of spring to provide additional
clearance. Install the wide crossbar with the washers and nuts supplied. Torque the nuts to 50-60 ft-lb and
double nut.
