TeraFlex JK: Alpine Long Control Arm Kit – 8-Arm (3-6” Lift) – Arms Only

TeraFlex JK: Alpine 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. Bolts to the factory control arm mounting brackets. Can be added to any existing suspension lift.

High-quality, dependable, maintenance-free, factory-style bushings provide excellent NVH damping and ride quality.

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.

Our CAD-designed 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.
