5. Install the offset U-bolts with the offset toward the axle 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
if required. Install the crossbar with the washers and nuts to connect to the main spring. Torque the nuts to 65 ft-
lb and double nut.
6. Adjust the U-bolts at the end to desired preload. The minimum tension adjustment is having enough tension on the
end U-bolts so that they do not loosen or rattle and move when the vehicle is driven over rough or bumpy surfaces.
Maximum adjustment is when the leaf cups have been deflected two (2) inches from their free state. DO NOT
EXCEED THE MAXIMUM ADJUSTMENT OF 2 INCHES.
7. When adjustment is complete, double nut to lock in adjustment.
8. Check your installation for clearance on all undercarriage components; wires, fuel, brake, and air conditioning
lines. Test drive the vehicle and recheck your installation, adjust as needed. Recheck on a monthly basis thereaf-
ter.

Maintenance and Inspection:
Your Hellwig Suspension Product is built to last. However, as with all vehicle systems, it requires routine
inspection. Inspect your Hellwig installation looking for secure hardware and tight fitting brackets and bush-
ings. If you do not perform this inspection, have your professional mechanic inspect as described.
