Teraflex 1614040 Sport ST4 4.5" Suspension Lift for 21-24 Jeep Wrangler JL Unlimited 4-Door 4xe
Fitting a Jeep Wrangler Unlimited JL with 37” tires does not take much. However, there are multiple components to consider if you want to do it comfortably. The Teraflex Sport ST4 4.5" Suspension Lift allows you to lift your Jeep without sacrificing the ride. This complete lift kit is 100% bolt-on for easy installation. It was designed specifically for the four-door Unlimited Wrangler JL, and includes Bump Stop Strike Pad Shims for every trim level. Teraflex includes their Front Control Arm Geometry Correction Brackets for improved suspension travel and driveline angle. Like other Sport ST kits, the ST4 reduces Noise, Vibration, and Harshness (NVH). For the best stability and handling, the ST3 is also available with Teraflex’s Falcon SP2 Monotube and Piggyback Shocks. Falcon SP2 shocks are precision-engineered for a specific vehicle and lift applications. They feature Teraflex’s proprietary Volume Optimized Damping (VOD) for race-inspired performance and comfort. Teraflex backs their lifts with a Limited Lifetime Warranty.

Versatile Lift: The “ST” in “Sport ST4” stands for Street and Trail. This full suspension lift kit is equally at home on and off road.
User Friendly Installation: No cutting, drilling, or welding is required to install this lift. All components simply bolt on using existing mounting locations.
Suspension Geometry: The included Teraflex Front Control Arm Geometry Correction Brackets (part number 1938125) reuse factory control arms, and improve handling. By lowering the control arm mount, these brackets maximize suspension travel while optimizing driveline angle.
Four Door Application: Teraflex engineered the Sport ST4 kit specifically for the Wrangler Unlimited JL. The coil springs and Falcon SP2 Shocks (when selected) are specifically tuned to the vehicle for precision handling and comfort.
