Features

JK Alpine IR Long Control Arms:

Adjustable Alpine IR Long Control Arms & Brackets balance front caster angle and pinion angles as well as optimize rear pinion angle and tune anti-squat geometry for proper suspension alignment on 3-6" lift kits
Alpine IR Long Control Arms are constructed from durable 42mm x 4mm (upper) or 50mm x 5mm (lower) wall DOM tube for maximum strength
On higher lifts, Alpine Long Arm Brackets reposition frame-end control arm mounting points to restore near factory orientation to reduce bushing stress during droop and shock load transferred through the Alpine IR Long Control Arms
Alpine Long Arm Brackets are gusseted and reinforced for superior strength w/ reduced NVH compared to other long arm kits

Product Details

TeraFlex JK: Alpine IR Long Control Arms and Alpine Long Arm Brackets 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.

On higher lifts TeraFlex JK: Alpine Long Arm Brackets (INCLUDED) 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.
