TeraFlex JK: Alpine IR Short Control Arms Kit – 8-Arms (2-4” Lift)
JK 4 Door, 2 Door 3"
1415611
TeraFlex JK: Alpine IR Long Control Arms and Alpine Long Arm Brackets (NOT INCLUDED) provide complete alignment adjustability and dependability for maximum performance on JK Wrangler/Unlimited models with 3–6” lifts. Can be added to an existing suspension lift.
Our innovative IR Bushings provide unrestricted rotation and flex as well as excellent NVH damping. These maintenance-free bushings improve on- and off-road ride quality and performance.
Must be used with TeraFlex JK: Alpine Long Arm Bracket Kit (# 1957000) – NOT INCLUDED. On higher lifts, Alpine Long Arm Brackets reposition the frame-end control arm mounting points to restore near factory orientation to reduce bushing stress during droop and shock load transferred through the control arms.
CAD-engineered Alpine Long Arm Brackets are designed for maximum strength. By streamlining the frame-end mounting points, we were able to incorporate both upper and lower mounts in each bracket thus simplifying installation while maintaining a factory appearance.
