INSTALLATION INSTRUCTIONS

Thank you for purchasing a quality Hellwig Product.

PLEASE READ THIS INSTRUCTION SHEET COMPLETELY BEFORE STARTING YOUR INSTALLATION PROCEDURES.

1. Lay out the spring leaves into two (2) sets. Each will consist of a main leaf with u-bolt cups and a second leaf

without cups. Lay the leaves so that the long ends are all in the same direction. Stack the leaves so that the

main leaf is on top. The long end of the spring stack must be installed toward the rear of the vehicle and the

short end toward the front.

2. Place the spring stack 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.

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.
