INSTRUCTIONS
1. With the front wheels securely blocked, raise the rear of the car to an adequate working height, then
support the chassis securely with jack stands leaving the differential slightly supported with the jack. Place
the jack under the rear axle to support but do not lift.
On The Driver's Side:
2. Remove the screw retaining the brake line to the outside of the stock rear lower control arm. Discard
the stock hardware, as you will not be reusing it.
3. Unbolt the shock from the rear axle, and pull it clear of the mounting stud.
4. Remove the coil spring retainer plate from the stock rear lower control arm. USE EXTREME CAUTION!
There will be nothing holding the spring to the control arm except the weight of the vehicle. Remove the
spring. Only a trained technician should attempt this. The stock springs are under a heavy stress load and
can cause injury if removed improperly.
5. With the spring removed you may loosen and remove the hardware attaching the control arm to the
body and axle. Use a wrench in the access hole at the front of the control arm in the frame to reach the
connecting hardware. You may have to move the exhaust system to remove the bolt at the front of the
arm.
6. The hardware at the rear of the control arm is easily accessed and should be removed. With all of the
hardware removed the stock control arm should drop out of place.
7. Install the Spohn rear lower control arm into the mounting locations on the frame and axle. Use the
stock hardware to secure our arm in place. Do not tighten the hardware until both ends of the arm have
been connected to the axle and frame.
On The Passenger's Side:
Repeat Steps 2-7 on the Passenger's side.
8. Reinstall both springs. Only a trained technician should attempt this. Use the welded spring seats on
the Spohn control arms to center and mount the springs.
9. On both Spohn rear lower control arms place the round spring retainer plate on top of the bottom of the
spring once it is centered on the LCA's spring seat. Use the provided 1/2” hardware to hold the plate
down. The bolt should be placed through the bottom of the LCA and the nut should be on top of the
retainer plate. Fully tighten the hardware. The plate will deform to fit each spring individually as it is
tightened down.
10. Reinstall both shocks onto the mounting studs and fully tighten.
11. Reattach the brake line to the outside of the Spohn control arm using the tapped hole on the outside
of the control arm. Use the supplied 1/4”-28 x 1/2” long flanged head bolts.
