Hellwig Load Pro Series LP 35 - Manual

INSTALLATION INSTRUCTIONS
Thank you for purchasing a quality Hellwig Product.
PLEASE READ THIS INSTRUCTION SHEET COMPLETELY BEFORE STARTING YOUR INSTALLATIONPROCEDURES.
1. Raise the rear of the vehicle by the frame so that the rear tires are just slightly contacting the floor. Be sure to
Block the front tires and use Jack Stands to support the vehicle by the frame. This will increase the vehicle’s
spring arch to ease installation.
2. Lay out the spring leaves into two (2) sets. Each will consist of a long, medium and a short leaf. The hole in
the middle of the leaves is punched (1”) off center. Lay the leaves so that the long ands are all in the same
direction.
3. Stack the leaves so that the short leaf is on the bottom and the long leaf is on the top. Use the (3/8”) bolt, nut
and lock washer that are provided to tighten the spring stack tightly. Tighten this center bolt completely.
4. Place the spring stack on top of the Step Brackets and install the (5) hole plate on top of the spring stack.
Using the small U-bolts and the (7/16”) lock nuts that are provided mount the spring stacks to the Step
Brackets with the (5) hole plate. Tighten completely. Be sure that the springs are straight in line with the Step
Bracket. SEE DIAGRAM.
5. Place the assembled spring on top of the truck springs. In most cases the long ends of the springs go towards
the rear. Align the springs to be centered over, and in line with the truck springs from front to rear. Front to
rear adjustment may be needed to position the Helper Springs and clear any vehicle components or spring
alignment clamps.
6. Install the medium U-bolts over the ends of the Step Brackets and install the crossbar with the washers and
double nuts to connect the Step Brackets to the truck springs. Leave loose at this time.
7. Place the long U-bolts on the ends of the Helper Springs and install the crossbars with the washers and double
nuts. Leave loose at this time. A C-clamp may be needed to compress the helper spring ends to attach the
crossbars and start the threads of the nuts.
