JK: Alpine IR Long Control Arm Kit – Front Upper (3-6" Lift)
TeraFlex JK: Alpine IR Long Control Arms & Alpine Long Arm Brackets provide maximum performance on JK Wrangler/Unlimited models with 3-6" lifts. Innovative IR Bushings provide unrestricted rotation and flex as well as excellent NVH damping.
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.
