USE OF THIS PRODUCT IS ACCEPTANCE OF SELLER'S DISCLAIMER OF WARRANTY!
By their very nature, competition components are constantly pushed to their limits. While our components
are designed to withstand intense race conditions, it is impossible to control the quality of installation or
the varying conditions in which they are used. It is for this reason that absolutely no warranty or
guarantee is either written or implied. Neither the seller nor the manufacturer will be liable for any loss,
damage, or injury - direct or indirect - arising from the use of or inability to determine the use of any
product. Before using, the user should determine the suitability of the product for its intended use, and
the user shall assume all responsibility in connection therewith. Spohn Performance, Inc. makes no
guarantee as to the legality for any specific class. Spohn Performance, Inc. makes no claims, nor does it
intend its products to be used in street driven vehicles. Spohn Performance, Inc. reserves the right to

INSTRUCTIONS
Note: Control arms ship jig set at stock length.
1. Lift rear of vehicle and support by frame rails. DO NOT SUPPORT BY REAR END!
2. Use a floor jack and place under rear axle to support the rear end.
3. Remove the rear and the front rear upper control arm bolts and nuts and remove
the stock rear upper control arm. The axle will shift slightly rearward (only swap one
UCA at a time, do each side separately).
4. Install the Spohn rear upper control arm using the jack to help position the rear
axle properly. 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 100
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's hex and turn it clockwise or counter-clockwise to lengthen
or shorten the control arm. Once set, tighten all of the jam nuts.
7. The poly bushings come pre-lubed. DO NOT use petroleum-based grease on your
poly bushings! Poly bushings must be lubricated with synthetic silicone based
waterproof grease. These are the manufacturer’s recommendations to prevent
premature bushing wear, and will keep things "squeak-free". You can order this
grease from Spohn Performance using our Part# 902. Do not over grease the
bushings! You only need a couple pumps of grease. Over greasing will cause the
bushings to balloon from the hydraulic pressure inside of the sleeve and they will fail.
