Features & Product Details

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 replacing the preset front lower Sport Flexarms with front control arm Sport Brackets as well as adding an adjustable rear track bar bracket. This kit allows for larger tires, without compromising driving comfort and trail capabilities.

The formative Sport ST4 Suspension System can be installed on Friday, wheeled on Saturday, and go for a drive on Sunday.

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. 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. Bolt on installation- no welding or drilling required. Does NOT include shocks.

TeraFlex adjustable piggyback shocks provide more vehcile stability for the Jeep JL Wrangler If you spend most of your time off the road than on it, it's probably a good idea to upgrade your Jeep's suspension. Designed for applications with a 2-4.5" lift kit, the TeraFlex Falcon SP2 3.3 Adjustable Piggyback Front & Rear Shocks is one of the best choices for those who live life to the fullest. The goal of these new and improved Falcon shocks is to make any Jeep more stable and in control without comprising comfort. Unlike other comparable options, these parts are not just adapted for use in rugged terrain; they're specifically built for them. Your stock suspension components aren't the best for extreme off-road applications like rolling over rocks or slugging through mud and sand. Ideally, you'd need larger tires and wheels to push your Jeep through tougher applications. These shocks give your Jeep additional frame clearance for larger tire/wheel combinations while improving suspension travel and articulation over stock. Moreover, these shocks tune both the compression rebound within the shocks, allowing you to preset the performance for city roads, tough trails, or whatever configuration best fits your specific driving style. The race-inspired performance for increased vehicle stability helps to improve dynamic body roll and low speed dampening for the best possible experience off-road. Designed for efficient JL suspension travel and articulation while improving low-speed dampening

Teraflex designed their Falcon SP2 3.3 Adjustable Piggyback Shocks using premium materials for maximum strength and long-lasting functionality. The 2.25" thick hard-anodized aluminum shock body was engineered to handle even the most extreme applications. Likewise, the 3/4" induction-hardened chrome plated shaft resists rock damage, corrosion, and shaft buckling. These shocks use a full synthetic Red Line shock oil for consistent performance across all temperatures and faster heat dissipation during harsh applications. Moreover, these shocks feature a 1,000 hour salt spray corrosion test on all hardware, ensuring long-lasting performance for your off-road warrior. These vehicle-specific shock absorbers install directly to your Jeep's existing components for a simple and straightforward bolt-on process.Teraflex includes all of the necessary hardware and mounting instructions, and backs this kit with a limited 3-year Warranty. See the quick start guide and mode adjust sheet for more details.
