TeraFlex JL: Alpine Long Control Arms and Alpine Long Arm Brackets (NOT INCLUDED) provide complete alignment adjustability and dependability for maximum performance on JL Wrangler/Unlimited models with 3–6in lifts. Can be added to any existing suspension lift. High-quality, dependable, maintenance-free, factory-style bushings provide excellent NVH damping and ride quality. CAD-engineered Alpine Long Arm Brackets (NOT INCLUDED) 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. Must be used with Alpine Long Arm Bracket Kit (JL 2-Door: 1958002 or JL 4-Door: # 1958000) – NOT INCLUDED.
