INSTRUCTIONS
1. Lift rear of vehicle and support by frame rails. DO NOT SUPPORT BY REAREND!
2. Use a floor jack and place under rear axle to support the rear.
3. Remove the front and rear upper control arm bolts and nuts and remove control
arm. The axle may shift slightly rearward. Do one control arm at a time.
4. Install the Spohn upper control arm using the jack to help position the rear axle
properly. The del-sphere end has two spacers on each side. This comes assembled
and wire tied in place so you can see how the assembly is to be installed. Note: The
del-sphere end is right hand threaded. Make the bolts hand tight only at this time.
Do one side then do the other side.
5. Lower vehicle to ride height (suspension loaded) and tighten all bolts to 72
ft./lbs.
6. One end of the adjuster is left hand threaded and the other end is right hand
threaded. To adjust the length of your control arm loosen both jam nuts and put a
wrench on the adjuster and turn it clockwise or counter-clockwise to lengthen or
shorten the control arm. Once set, tighten the jam nuts. Note: UCAs are shipped jig
set at stock length.
7. Jam nuts are known to work loose over time. To prevent this we recommend
that after you have the UCAs set to your desired length you apply some REMOVABLE
strength (blue) Loctite to the adjuster threads and then tighten up the jam nuts on
each end of the adjuster.
