1. Jack up vehicle by the frame just until the tires are ready to leave the ground. Be sure that the vehicle is on a flat hard surface, use tire
blocks and safety stands.
2. Place the accessory springs on top of the vehicle’s springs as per drawing. On some vehicles it may be necessary to bend or remove
the vehicle’s spring keepers if the helper spring will not rest down on top of the vehicle’s 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 on the rear of the vehicle leaf springs.
The end where both leaves are clamped together mount toward the axle as close as possible without making contact.
3. Install the U-bolts on the accessory springs. Install the crossbars, washers and nuts. Tighten the U-bolts on the accessory spring.
Double nut this U-bolt. The shorter U-bolts mount at the axle and the longer U-bolts mount at the spring ands to allow for adjustment.
4. Install the crossbars, washers and nuts on the end U-bolts. Tighten only until enough threads show through to install the lock nut.
5. To adjust the helper spring for more load capacity, remove the lock nut from the end and draw the U-bolt tighter. Be sure to double
nut after each adjustment made.
6. Bounce the vehicle and check for clearance on all undercarriage components. Check and see that all wiring, brake and fuel lines
are free and clear of this installation.
7. Recheck your installation. Are all the lock nuts installed? Are the U-bolts closest to the axle drawn down completely tight? After on
week of driving recheck your installation, check to see that the helper springs are tight and have not shifted.
