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
make changes in design or add to or improve on their product without incurring any obligation to install

Performance, Inc. harmless from any claim, action or demand arising out of or incident to the Buyer's
installation or use of products purchased from Spohn Performance, Inc.
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.
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 arm is right hand threaded. To adjust the length of your control arm
loosen the jam nut and turn the end in or out to lengthen or shorten the control arm. Once
set, tighten the jam nut. Jam nuts are known to work loose over time. To prevent this we
recommend that after you have the arms set to your desired length you apply some
REMOVABLE strength (Blue) Loctite to the threads and then tighten up 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 pre-mature 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.
