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 Extended-Travel 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. Carefully selected components allow Sport ST Extended-Travel Suspense Systems to safely provide 16” of rear suspension travel.
Front Control Arm Sport Frame Brackets balance front caster angle and pinion angle 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. Extended-Travel Suspension Systems include carefully selected extended-travel components to safely provide 16” of rear suspension travel.
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.
