  • These all-inclusive TeraFlex Sport ST (Street & Trail) Suspensions Systems deliver true street & trail (ST) performance and capability in a dependable and maintenance-free package.

    The 4.5'' Sport ST4 Suspension System's higher lift height allows for larger tires and a dominating stance, while maintaining a comfortable and stable ride on both highway and trail. TeraFlex's robust Front Control Arm Sport Frame Brackets provide steering geometry correction as well as positive braking control with reduced nosedive.

    Sport ST Suspension Systems feature lift coil springs, bump stops, and front sway bar quick disconnects optimized for stated lift height as well as tire and component clearance. Front Control Arm Sport Frame Brackets balance front caster and pinion angles to improve front suspension geometry on vehicles with 2.5-4.5'' lifts. The Front and Rear Track Bar Axle Brackets improve steering response, center the axles to optimize vehicle roll center, and reduce body roll for unsurpassed handling.

    This results in a simple install and drive bolt-on installation with no cutting or welding required. These maintenance-free suspension systems provide superior on-road ride quality and comfort with maximum off-road flex. TeraFlex suspension systems provide reduced noise, vibration, and harshness (NVH).

    Sport ST Suspension Systems can be installed on Friday, wheeled on Saturday, and driven to church on Sunday!

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