Product Overview

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.

The 1.5” Sport ST1 Spring Lift System is prefect for the Jeeper who wants the look of a lifted rig and larger tires for more ground clearance.

Thanks to their minimal impact on factory suspension geometry, the coil springs will not compromise highway ride or handling, while the Progressive Front Bump Stops prevent tire contact and shock bottoming.

This is a cost-effective solution for your daily driver/trail Jeep.

All Sport ST Suspension Systems feature lift coil springs, bump stops, and front sway bar quick disconnects optimized for stated lift height.

The Sport ST1 has minimal impact on factory geometry.

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!

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 ST1 Spring Lift Systems are offered with Falcon Series 2.1 Monotube Shocks or without shock absorbers.

Other Falcon shocks are available separately.
