🧾 Overview
The TeraFlex Wrangler JL 4-Door 2.5 Inch Sport ST2 Suspension System is an all-inclusive Street & Trail lift engineered for Jeep owners who want a stable highway commute paired with confident trail performance. Built on the proven Sport ST platform, this system delivers dependable, maintenance-free capability with a straightforward bolt-on design.
Featuring preset Front Lower Sport Control Arms, the ST2 system optimizes caster and pinion angles to improve steering feel and on-road handling while maintaining proper suspension geometry. The additional lift height over the ST1 clears larger tires without sacrificing stability, and carefully matched springs, bump stops, and sway bar components provide smooth ride quality with improved articulation off-road.
Note: Shocks are not included. Falcon Performance Shocks are recommended for optimal compression, rebound, and vehicle stability.
