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.
Innovative IR Bushings provide unrestricted rotation and flex as well as excellent NVH (noise, vibration, harshness) 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, Teraflex incorporated both upper and lower mounts in each bracket thus simplifying installation while maintaining a factory appearance.
FEATURES/BENEFITS
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
JK 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
• TeraFlex Lifetime Warranty against defects
