Teraflex Alpine IR control arms integrates an innovative IR Bushing that provides unrestricted rotation and flex as well as excellent NVH damping. These maintenance-free bushings improve on- and off-road ride quality and performance that balance front caster angle and pinion angles as well as optimize rear pinion angle and tune anti-squat geometry for proper suspension alignment on 2-4” lift kits. Alpine IR Short Control Arms are constructed from durable 42mm x 4mm wall DOM tube for maximum strength and bolts to the factory control arm mounting brackets – no welding required!
On higher lifts, Alpine IR Long Control Arms and 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
