TeraFlex JK: Alpine IR Long Control Arms & Alpine Long Arm Brackets provide complete alignment adjustability for maximum performance on JK Wrangler/Unlimited models with 3-6” lifts. Can be added to an existing suspension lift. Their 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, 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.
These CAD-designed TeraFlex JK: Alpine Long Arm Brackets are engineered 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.

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
Bolt-on Alpine Long Arm Brackets are gusseted and reinforced for superior strength w/ reduce NVH compared to other long arm kits
JK Alpine IR [Long] Control Arms:
Re-centers axles in the wheel well for proper suspension movement. Can also be used to increase wheelbase Full range of movement will not restrict articulation or flex off-road Innovative IR Bushings provide unrestricted rotation and flex as well as excellent NVH damping Maintenance-free IR Bushings improve on- and off-road ride quality and performance Zero maintenance forged threaded joints for smooth quiet flex Premium black e-dipped coating on tube and forged rod end housing provides superior durability and corrosion resistance Anodized 6061-T6 aluminum clamp collar to secure rod end after length adjustment
