Welcome
CONGRATULATIONS on purchasing a set of new Adjust-
able Control Arms from JKS Manufacturing. We are com-
mitted to providing you with the best products available and

Important
COMPATIBLE WITH original 3-link suspension con-
figuration and vehicle ride height up to 6.0”.
SUSPENSION COMPONENTS THAT HAVE RUBBER
BUSHINGS must be tightened with vehicle on level
ground and at normal ride height. The springs must be
supporting the weight of the vehicle when the hard-
ware is torqued; or else ride comfort could be affected
and premature bushing wear may occur.
RUBBER BUSHINGS MUST NEVER BE LUBRICATED,
as doing so will impair performance and longevity.
SUPPLIED FLAT WASHER SHIMS must be used to fill
the void between the suspension arm brackets and
control arm bushings. Additional shims are included for
customers installing front Control Arms at same time.
REFER TO FACTORY SERVICE MANUAL for informa-
tion and procedures not covered in these instructions.

est alignment of mounting hardware.

Installation
1. REMOVE ORIGINAL LOWER
SUSPENSION ARM
Raise and support the vehicle chassis with jack
stands positioned in front of the rear lower suspen-
sion arm brackets.
Raise the axle housing back into position and sup-
port with a hydraulic jack. HINT: The axle housing
should be evenly supported and the suspension
at normal ride height. Do not attempt removal or
installation with the suspension extended, or the
axle drooped, as this will place tension on suspen-
sion arm mounting hardware.
