Engineered with drivability in mind, the ultra-simple TeraFlex JK 4dr: 2.5” Coil Spring Lift Kit comes with the basic components required to fit larger tires for increased ground clearance and better off-road capability without compromising on-road handling.

Every TeraFlex suspension system is engineered with drivability and performance in mind.

Properly developed suspension geometry, roll center, and load tuning ensures that all factory stability controls remain functional and within the parameters that Jeep originally engineered into the vehicle.

Not only do TeraFlex kits drive straight, but they will crawl over anything to get you there and back!

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.

2.5” Coil Spring Base Lift Kits are offered with TeraFlex 9550 VSS Twin-Tube Shocks, with shock extensions, or without shock absorbers or extensions.

Falcon Performance Shocks are available separately.

I installed the the 2.5" suspension lift. The ride is very smooth and glides over the bumps on the road. When I'm offroading, I'm also very happy with the handling and performance it provides me.

2016/JKU Rubicon I installed this lift myself. I did not have a vehicle lift so had to do it the old school way (Jack and Jack Stands) Took me right at 5 hrs. Hardest part was getting the front springs in, but a little brute force is all it took. I am very happy with this lift and the quality of the components. The ride is very comparable to stock. I would absolutely recommend this lift to anyone. Thank you TeraFlex! I did take about a week and watched every YouTube install video I could find... when it came time for the install, I knew exactly what to do.... I highly recommend you watching videos (worked well for me). The main reason I went with this lift is because I installed a Warn M8000 winch. The winch lowered the front end of my jeep just enough to bother me. I did my research and decided to go with TeraFlex based off of the excellent reviews not only of this lift but of the TeraFlex support. I did call TeraFlex just to confirm that this lift would be the best option for "me" and the support staff said that this lift since it gets its lift from the springs was the perfect fit for what I was trying to achieve....

A great upgrade from any stock suspension. The lift provides great clearance for my 35's and handles great for off roading . Very smooth ride . Would differently purchase this again.
