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 or 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 jack and place under rear axle to support but do not lift.
3. Remove both front and rear control arm bolts and nuts and remove control arm. The axle
will shift slightly rearward. Only remove and install one control arm at a time.
4. Install control arms using the jack to help position the rear axle properly. Make the bolts
hand tight only at this time.
5. Lower vehicle to regular ride height 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 LCAs simply put a wrench on the adjuster and turn it clockwise or
counter-clockwise to lengthen or shorten the LCA. Note: LCAs are shipped jig set at stock
length.
7. Place the poly end at the front (chassis) LCA mount, and the del-sphere at the rear
housing LCA mount. 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.
8. 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 poly 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.
9. Jam nuts are known to work loose over time. To prevent this we recommend that after you
have the LCAs 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.
