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. At home on black diamond trails or city streets, the 3in Sport ST3 Suspension System features preset Front Lower, Rear Upper, and Rear Lower Sport Control Arms, Front SpeedBump & Rear Progressive 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- or off-road prowess. All Sport ST 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. Sport ST Suspension Systems add preset Sport Control Arms (ST3: front lower, rear upper, rear lower) to balance front caster and pinion angles to improve front suspension geometry as well as optimize rear pinion angles, anti-squat geometry, and tire position on vehicles with 2.5–3in lifts. The Front HD Forged Adjustable Track Bar and Rear Track Bar Axle Bracket 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 drivein 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! 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 ST3 Suspension Systems are offered with select Falcon Shocks or without shock absorbers.
