Jack up the vehicle by the frame so that the rear wheels are slightly touching the ground. Be sure to use safety stands and block

the front tires.

2. Place the accessory springs on top of the vehicles as per drawing. On some vehicles it may be necessary to bend or remove the vehi-

cles spring keepers, so that the helper spring will rest on top of the vehicles springs. The helper spring U-bolts will do the same job

as the factory keepers after tightening.

NOTE: The short leaf assembly will mount on the front and the long leaf assembly will mount to the rear of the vehicles springs.

The end where both leaves are clamped together mount as close as possible to the axle without making contact.

3. Install the crossbar, washers and nuts on the U-bolts closest to the axle. Tighten down completely and double nuts.

4. Install the crossbar, washers and nuts on the end U-bolts. Tighten just enough to allow the lock nut to be installed.

5. Lower the vehicle to the ground. Tighten and adjust the helper spring for desired tension and height. To adjust the helper spring for

more load capacity draw the nuts tighter, loosen to relief load capacity. Make certain that double nuts are used after each and every

adjustment made.

6. Bounce the vehicle and check for clearance on all under carriage components. Check and see that all wiring, brake and fuel lines are

free of this installation.

7. After one week of driving recheck your installation readjust if necessary. Recheck on a regular monthly basis thereafter.
