TeraFlex JT: Alpine IR Long Arms and Long Arm Brackets provide complete alignment adjustability and dependability for maximum performance on JT Gladiator models with 3-6'' lifts.
Our 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.
CAD-engineered TeraFlex JT: Long Arm Brackets 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. Front Long Arm Suspension Crossmember provides additional strength.
Can be added to any existing suspension lift.

- 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 (NOT INCLUDED) 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 (NOT INCLUDED) 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 w/ 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 (NOT INCLUDED) provides additional strength
- Install and drive simple bolt-on installation ''" no welding required
Adjustable Control Arms (all):
