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 for 2018 JL is no exception. But we all know that there are near infinite ways to improve upon 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 JL Wrangler/Unlimited?

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?

Other important factors include the tire diameter you want to run as well as budget.

 

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!

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.

Spacer Lift Kits

TeraFlex builds 1.5” and 2.5” Performance Spacer Lift Kits for those wanting to run larger tires on their daily drivers that also see moderate trail use.

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.
