JKS6155 JKS Adjustable Control Arm Installation 2 Page
 Remove the lower suspension arm bolt and nut
from the axle housing bracket. Retain the original
mounting hardware.
 Remove the bolt and flag nut from the chassis rail
bracket. Retain the original mounting hardware.
 Remove the original lower suspension arm from
the vehicle.
‰ 2. SET CONTROL ARM LENGTH
Adjustable Control Arms are fully collapsed when supplied
from JKS and must be adjusted to the desired lengths
before installation.
The working length of each lower Control Arm can be
increased (up to 2.625” longer), decreased (up to 0.75”
shorter), or exactly the same as the OE suspension arm.
 Determine ideal Control Arm length for your ap-
plication by considering factors such as:
 Length of OE suspension arm
 Tire Clearance
 Pinion Angle
 Rotate adjustable end of Control Arm until the
desired length is achieved.
 Adjust corresponding Control Arm to exact same
length.
‰ 3. INSTALL CONTROL ARM
 Apply anti-seize lubricant to bolt threads of original
mounting hardware.
 Mount the non-rotating (BLACK) end of Adjustable
Control Arm to the chassis rail bracket.
 Install the original mounting bolt and flag nut.
Finger tighten the bolt. DO NOT torque mounting
hardware until instructed.
 Mount the rotating (GOLD) end of Adjustable
Control Arm to the axle housing bracket with the
greaseable fitting facing up.
 Install the original mounting bolt and finger tighten
the nut. DO NOT torque mounting hardware until
instructed.
HINT: If mounting bolt is difficult to install due to misalign-
ment of Control Arm bushing with mounting bracket, either
(1) adjust height of axle housing with hydraulic jack, (2)
move axle housing into position with a heavy-duty ratchet
strap, or (3) temporarily disconnect track bar until mount-
ing holes align.
‰ 4. TIGHTEN MOUNTING HARDWARE
 Once both Adjustable Control Arms have been
properly installed, lower the vehicle to the ground
until coil springs are supporting the full weight of
vehicle.
 Using a torque wrench, tighten all mounting hard-
ware to 125 ft-lbs.
‰ 5. POST-INSTALLATION INSTRUCTIONS
 Adjustable Control Arms are supplied pre-lubri-
cated, although it will be necessary to add more
grease after they have been adjusted and installed
on the vehicle. Refer to Maintenance section for
specific lubrication instructions.
Maintenance
Control Arms should be greased regularly as part of
vehicle maintenance schedule. Lubricate using moisture
resistant marine style grease and a hand-pump grease
gun. DO NOT use a pneumatic grease gun. Add grease
slowly until resistance is felt. The internal spring-loaded
seal can be damaged by forcing too much grease into
Control Arms.
