Features & Highlights:
- 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 kitsJK Alpine IR Control Arms (all):
- 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

More Information:
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.
