Leveled up!!
You get what you pay for and that’s quality. Teraflex has outstanding products . This leveled out my Jeep without affecting the handling. Holds up to the abuse of the trails in northern Wisco.

Easy install
Great product. The factory isolators snap into the bottom and then they both snap into the frame/body. The spring retainer is nice and absent on many of the cheaper alternatives. I installed these with my 2.5" Rough Country lift and couldn't be happier. Distance between top of tire and fender is about 8" on all 4 corners with the stock 255/75R17 BFG mud terrains. 285/75R17 tires coming soon.

Leveling puck
Works to take “gangster lean” out of JKU with 4.5” lift. Also needs one for the passenger front to level it out.

Teraflex comes through again
Simple and fits perfectly. Used this to level the rear of my 2015 JK that already has a Teraflex 2.5” suspension lift. The rear seat about an inch lower than the front so this made everything level. Install took about an hour. Couldn’t be happier

Not an exact fit for 2024 gladiator, but I made it work...

Great Fix For Jeep Lean!
I had a 1 ¼" lean on the passenger rear before my lift kit and after it was exactly the same, I purchased the 1" spacer due to not seeing a 1 ¼" one and it did exactly as described. I now have a ¼" lean but almost unnoticeable!

Sturdy, well made, inexpensive 1 inch boost.
Cheap easy way to get a 1 inch boost and has the added benefit of the center spring guide. Make absolutely sure when you go to install these that you have disconected EVERYTHING before lowering your axle enough to pull the rear springs and pop these into place. This includes both upper brake line mounts on both sides of the outer frame rails in the wheel wells, any wiring going from the frame to the axle, the E-brake cable mount to the underside of the body above the center of the axle, and the shocks last. You will need to guide the springs back to the correct position by hand until fully seated. I used the springs themselves to pop the spacer into the mount collar. Use a little grease on the upper spacer collar.

Used this to fix the notorious JK lean on passenger rear side. Worked great.
