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.

Developed for the Jeep enthusiast looking for a stable highway commute and comfortable trail performance, the 2.5” Sport ST2 Suspension System features front lower Sport Flexarms and Falcon Progressive Bump Stops. The preset Sport Flexarms optimize steering geometry for improved highway handling. The additional lift height over the Sport ST1 clears larger diameter tires without compromising on- and off-road stability.

All Sport ST Suspension Systems feature coil springs and bump stops optimized for stated lift height as well as tire and component clearance.

The Sport ST2 adds front lower Sport Flexarm preset control arms that optimize caster and pinion angles to restore front suspension geometry. This system also includes a Rear Track Bar Bracket to improve steering response, 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, welding, or alignment 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. Sport ST Suspension Systems are offered with a choice of Falcon shock absorbers or without shocks.
