🧾 Overview
The TeraFlex 2.5" Alpine RT2 Short Arm Suspension System for the Jeep Gladiator JT is engineered for drivers who demand top-tier on-road comfort and uncompromising off-road performance. Built on the proven Alpine Rogue Trail (RT) platform, this system combines premium geometry correction, articulation control, and ride refinement into one comprehensive suspension solution.
At the heart of the RT2 system are TeraFlex Alpine IR Short Arms featuring patented Independent Rotation (IR) Bushings. These bushings eliminate bind throughout suspension travel, allowing unrestricted droop, smoother articulation, and a noticeably quieter, more controlled ride both on the highway and on the trail.
Front and rear HD forged adjustable track bars center the axles, restore proper roll center, and dramatically improve steering response while reducing body roll. SpeedBump progressive bump stops help absorb harsh impacts from unexpected trail obstacles, protecting suspension components and improving ride quality.
This system is designed to correct caster, pinion angles, anti-squat geometry, and tire placement on Gladiator models running up to 4.5 inches of lift—delivering balanced, predictable handling across all terrains.
