Despite increased government regulations and customer demand for more comfort and convenience, the Jeep Wrangler/Unlimited remains true to its off-roading roots. And the all-new Wrangler-based 2020 JT Gladiator is no exception. But we all know that there are near-infinite ways to improve our Jeeps to fit our lifestyle and our needs. But how does one sift through the many lift options out there? The journey begins with asking yourself important questions, such as:
What do I want out of my JT Gladiator?
Do I use my Jeep as a commuter or family car? Is it a hardcore weekend warrior used for escaping city life and paved streets? Or is it a dual-purpose rig used for both?
All these questions must be taken into consideration when choosing a lift kit.
Bigger isn’t always better. But sometimes bigger is better. And that’s why we offer a variety of suspension systems from mild to wild— and several in between — so our customers can find the configuration for their rig that’s best suited to their needs.
For more information on a specific suspension system, click the links in the article or check out our FAQ page HERE!
JT Gladiator suspension lifts do 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 are available separately.
Spacer Leveling Kit and Spacer Lift Kits
TeraFlex builds a 1.5” Performance Spacer Leveling Kit as well as 2.5” and 3.5” Performance Spacer Lift Kits for those wanting to run larger tires on their daily drivers that also see moderate trail use.
Even when reality demands that you keep your JT Gladiator family-friendly, TeraFlex will satisfy your primal need to go big. Our JT: 1.5” Performance Spacer Leveling Kit allows you to run a larger tire with added clearance on the trail, all while maintaining family-friendly versatility.
Additionally, the extra height helps compensate for heavier aftermarket bumpers and winch, a larger spare tire, or weekend gear. Works with stock-length shock absorbers.
Includes: 1” lift coil spring spacers (front), 0.5” lift coil spring spacers (front), 1” bump stop strike pad extensions (front), all necessary hardware.
The TeraFlex JT: 2.5” Performance Spacer Lift Kit is the most economical way to fit larger tires and increase ground clearance on your JT Gladiator with the fewest modifications.

Most suspension lifts do 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.
