Through the dawn of Jeep time, the reality has been that a long-arm suspension system comes with some impressive improvements to ride, handling, and suspension travel. That nugget of truth remains valid even today, and with the advent of the JT Gladiator, that long-arm suspension upgrade will open all the performance capabilities lurking in that trail-taming 136” wheelbase.

 

3.5–4.5” Long Arm Extended-Travel Suspension Systems

Adjustable Long Control Arms balance front caster angle and pinion angles as well as optimize rear pinion angles, anti-squat geometry, and tire position on vehicles with 3–6” lifts. On higher lifts, Long Arm Brackets reposition frame-end control arm mounting points to restore near factory orientation to reduce bushing stress during extreme droop as well as shock load transferred through the Long Control Arms.

JT Gladiator Extended-Travel Suspension Systems include carefully selected components to safely provide 16” of rear suspension travel.

This results in improved suspension geometry and relaxed control arm angles for superior ride quality and performance regardless of the terrain. These systems restore front and rear roll axis angles to minimize brake dive and acceleration squat. TeraFlex suspension systems provide reduced noise, vibration, and harshness (NVH).

Does NOT include shocks. We recommend Falcon Performance Shocks. Falcon shock absorbers and TeraFlex lift coil springs have been engineered together to improve compression and rebound for optimal vehicle stability. Falcon shock absorbers and steering stabilizers are available separately.
