Fitment and Installation Notes

• - Alpine IR Control Arms (Short / Long):
• - Innovative, maintenance-free IR Bushings provide unrestricted rotation and flex as well as excellent NVH damping to improve on- and off-road ride quality and performance JL / JT: Long Control Arms (Alpine/IR) and Long Arm Brackets:
• - Adjustable Long Control Arms and Long Arm 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
• - Long Control Arms are constructed from durable 42mm x 4mm (front upper) or 50mm x 5mm (front lower, rear upper, rear lower) wall DOM tube for maximum strength
• - On higher lifts, bolt-on Long Arm Brackets reposition frame-end control arm mounting points to restore near factory orientation to reduce bushing stress during extreme droop and shock load transferred through the Long Control Arms
• - Long Arm Brackets are gusseted and reinforced for superior strength with reduced NVH compared to other long arm kits
• - Long Arm Brackets feature a premium triple-stage powder coating that provides superior durability and corrosion resistance
• - Front Long Arm Suspension Crossmember provides additional strength
• - Install and drive simple bolt-on installation - no welding required Adjustable 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
• - 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
