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.
The 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.
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, 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
