Use these TeraFlex JK: Coil Spring Spacers to level out a loaded vehicle. Compatible with stock height or lifted vehicles. Rear Coil Spring Spacers also incorporate our industry exclusive spring retainer and guide, which help realign the coil spring to its proper location during extreme articulation preventing the spring from dropping out.

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.   Developed for the Jeep enthusiast looking for a stable highway commute and comfortable trail performance, the 2.5” Sport ST2 Suspension System features Front Lower Sport Control Arms and Progressive Bump Stops. The preset Sport Control Arms optimize steering geometry for improved highway handling. The additional lift height over the Sport ST1 clears larger diameter tires without compromising on- and off-road stability.   Sport ST Suspension 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. Front Lower Sport Control Arms balance front caster and pinion angles to improve front suspension geometry on vehicles with 1.5–3.5” lifts. The Rear Track Bar Axle Bracket improves steering response, centers the axle to optimize vehicle roll center, and reduces body roll for unsurpassed handling.   This results in a simple “install and drive” 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!   Does NOT include shocks. 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. Falcon shock absorbers and steering stabilizers available separately.

TeraFlex JT: Rear Lift Coil Springs are perfectly engineered for your JT Jeep Gladiator. Our engineers focused on extensive rate tuning and dynamic balance between front and rear and side-to-side load bias to produce Lift Coil Springs that deliver unsurpassed highway handling and off-road performance.   Out back, we chose progressive triple-rate lift coil springs that provide optimal performance both on and off road as well as while towing. These progressive triple-rate coil springs provide consistent performance and predictable handling throughout normal street driving – just like a linear rate spring.   When the axle begins to droop, the softer sprung upper section of the coil spring begins to unwind for maximum flex and spring retention. The stiffer sprung lower section of the coil provides stability while towing. Additionally, we lowered the towing coils to improve ride quality while unladen.   We recommend pairing TeraFlex Lift Coil Springs with Falcon Performance Shocks for superior performance. TeraFlex coil springs and Falcon shock absorbers have been engineered together to improve both compression and rebound for optimal vehicle stability.

TeraFlex 4.5” Coil Spring Base Lift Kits include just the basic lift components only and do not have the drivability of a full suspension system.

Does NOT include shocks. We recommend Falcon Performance Shocks or TeraFlex 9550 VSS Twin-Tube Shocks. These are the only shock absorbers engineered to work with TeraFlex lift coil springs to improve both compression and rebound for optimal vehicle stability. 4.5” Coil Spring Base Lift Kits are offered with TeraFlex 9550 VSS Twin-Tube Shocks or without shock absorbers. Falcon Performance Shocks are available separately.
