This item ships for free! (Continental U.S. only)

The ultra-simple TeraFlex 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 shocks or shock extensions. 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 or with shock extensions or without shock absorbers. Falcon Performance Shocks are available separately.

Just did the 2.5" TF Coil Lift with Shock Extensions this past weekend. Took me on the ground with jack stands and 2 jacks about 8 hours to finish. When done it rides great, drives straight, no wobbles, shakes or noises. Gained about 3.25 in the front and about 2.5 in the rear in lift and it now sits level within 1/4 inch. Starting with installing the rear and it went real well, had 2 small issues/slow downs. 1. Broke the drivers side brake extension bolt (TF is nicely sending me another one) 2. The template for the rear trackbar frame kit did not line up as nicely as I hoped and I had to woller the hole out a little toward the top to get the bolt in nicely. On to the Front, no major hiccups there either, easy install and straight forward. Was not sure where to reroute the brake lines to so had to call TF for this one and they helped me out. All in all, I would definitely go this route again. Took some time but really performs and drives fantastic. Looks great and saved a few dollars without having to buy new shocks for now. I will definitely be sporting the TeraFlex Suspensions Logo on my front windshield. Great Product. Rob

I am not a mechanic. Some would say I'm actually mechanically UN-inclined. That said, with the help of my dad, I successfully installed this kit. The instructions are clear, and the install videos explain the install perfectly. The biggest obstacle was getting the front springs in, and after really loosening up the control arms, they went in with no issue. Now lifted 2.5" and with 35 inch NITTO TERA GRAPPLERS under neath, my rig drives just as good as stock. I couldn't be happier! Thanks Teraflex for a great product!
