Product Usage Instructions

1. Park the vehicle on a hard-level surface. Place wheel chocks in front and behind the front wheels to prevent rolling. Observe all safety precautions and wear safety glasses.
2. Raise the rear of the vehicle allowing the axle to hang free and rest the frame on the safety jack stands rated for the vehicle. Removal of the rear wheels is optional.
3. Starting on the driver’s side, remove the factory Bump Stop from the underside of the frame and set it aside. These can be removed by pulling sideways firmly and rotating them out of the holders.
4. Remove the lower bracket assembly parts, Lower Mounting Bracket [ITEME], and Axel Clamp Bracket [ITEM F] from the box. Then attach the Lower Mounting Bracket [ITEM E] to the lower (male) half of the Sumospring [ITEM A] using a 3/8-16 x 7/8 FHCS [ITEM H]. DO NOT apply Loctite at this stage and leave the bolt slightly loose to allow for alignment with the upper half of the Sumospring.
5. Set the upper half of the Sumospring on top of the lower and place the assembly on the driver-side axle housing with the lower bracket outboard cut-out located on the flange that extends from the spacer block between the factory u-bolts and against the factory spring-pack.
