The all-inclusive TeraFlex Sport ST (Street & Trail) Suspensions Systems deliver performance and capability in a dependable and maintenance-free package.
At home on the most extreme trails or around town, the 4.5” Sport ST4 Suspension System builds on the 3.5” lift Sport ST3 by adding taller coil springs, a revised front track bar bracket, an adjustable rear track bar bracket, and more.
The taller coil springs and additional components increase ground clearance without compromising on- and off-road prowess. No alignment is needed thanks to the front lower control arm drop brackets, heavy-duty forged front track bar bracket, and heavy-duty forged rear adjustable track bar bracket, which work to together to optimize correct caster angle, restore geometry, eliminate bump steer, restore vehicle roll center, and reduce body roll with 4.5” lift kits.
The Sport ST4 Suspension System can be installed on Friday, wheeled on Saturday, and driven to church on Sunday!
Does NOT include shocks. We recommend Falcon shock absorbers for superior performance. Falcon shocks and TeraFlex coil springs have been designed to work together to improve both compression and rebound for optimal vehicle stability.
