🧾 Overview
The TeraFlex 3.5" Sport ST3 Suspension System is a complete Street & Trail (ST) lift solution designed to improve ride quality, steering control, and off-road capability for the Jeep Wrangler JL Unlimited. Unlike basic spacer or coil-only kits, the ST3 system focuses on correcting suspension geometry to maintain proper handling at increased lift heights.
This system uses front control arm sport frame brackets and track bar correction components to restore caster and axle positioning, resulting in improved stability, reduced brake dive, and more predictable steering feel.
This is the no shock version, allowing you to pair the system with your preferred shocks based on your driving style and budget.
✔ 3.5" lift height for increased clearance and tire fitment
✔ Complete ST3 system with geometry correction components
✔ Improves ride quality, steering feel, and handling
✔ Designed for both daily driving and off-road use
✔ No shocks included – choose your own setup
🛠 Installation
- Bolt-on installation using standard tools. Professional installation recommended. Alignment required after install. Designed for drivers looking for improved handling and off-road performance without stepping into a full high-end suspension system.
