Regular price


These all-inclusive TeraFlex Sport ST (Street and Trail) Suspensions Systems deliver true street and trail (ST) performance and capability in a dependable and maintenance-free package. At home on black diamond trails or city streets, the 3 inch Sport ST3 Suspension System features front lower, rear upper, and rear lower preset Sport Control Arms, SpeedBump Front and Progressive Rear Bump Stops, front brake line anchors, and more.

Although the Sport ST3 clears the same size tires as the Sport ST2, the additional components increase ground clearance without compromising on- and off-road prowess. All Sport ST Suspension Systems feature lift coil springs, bump stops, and front sway bar quick disconnects optimized for stated lift height.

Sport ST2 and Sport ST3 Suspension Systems add preset Sport Control Arms (2.5 inch and up: front lower; 3 inch: rear upper, rear lower) to balance caster and pinion angles as well as optimize rear pinion angles, anti-squat geometry, and tire position.

These systems also include our HD Forged Adjustable Front Track Bar and rear track bar bracket, which 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, 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). Falcon shock absorbers and TeraFlex lift coil springs have been engineered together to improve both compression and rebound for optimal vehicle stability.

Sport ST3 Suspension Systems are offered with select Falcon Series Shocks including: 3.3 Fast Adjust, 3.1 Piggyback, 2.1 Monotube, or without shock absorbers.
