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.
The 4.5 inch Sport ST4 Suspension System's higher lift height allows for larger tires and a dominating stance, while maintaining a comfortable and stable ride on both highway and trail. TeraFlex's robust Front Control Arm Sport Brackets provide steering geometry correction as well as positive braking control with reduced nosedive.
All Sport ST Suspension Systems feature lift coil springs and bump stops optimized for stated lift height as well as tire and component clearance.
The Sport ST3 and Sport ST4 feature our Front Control Arm Sport Brackets that balance front caster and pinion angles to improve front suspension geometry. These systems also include Front (3.5 inch and up) and Rear (2.5 inch and up) Track Bar Brackets to 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 inch 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 SP2 Mode Adjust Performance Shocks. Falcon shock absorbers and TeraFlex lift coil springs have been engineered together to improve both compression and rebound for optimal vehicle stability. The Sport ST 4Suspension System is offered with a choice Falcon SP2 3.3 Fast Adjust Piggyback Shocks, Falcon SP2 3.1 Piggyback Shocks, or without shock absorbers.
