1. Bolt the upper StrongArm to the
body using ½” x 2 ½” bolts, flat
washers and lock washers. A shim is
supplied and may need to be installed
between the body and the arms to
achieve proper alignment.
2. The arms are preset at the factory
so the alignment should be close, but
the vehicle must be aligned before
driving.
Note: The upper arm mounting holes
on many cars have been redrilled 1”
lower. This is done to improve the
handling. Our cross shaft has the
drop built into it, make sure to use the
factory mounting holes.
3. Bolt the upper arm to the spindle
using the hardware and cotter pin
supplied.
4. Attach the Shockwave to the upper
StrongArm using a ½” x 2 ¼” bolt and
Nylok nut.
5. This control arm is designed to
work with our MuscleBar sway bar.
The end link will attach to the rear
mounting tab on the upper arm.
