Teraflex Rear 1/2" Coil Spacer Load Level Kit Reviews

Awesome simple install. I stacked 2 for a full 1inch lift in my Rubicon which came from the factory with a reverse rake.

Level out stance

This is exactly what I needed. I mounted two kits (one on top of the other) to get a total of 1" which compensated for the overweight of my "LoD bumper" and the sagging of the rear of my Jeep JL.
Questions
Robert K.
I would like to get 1/2 inch lift in the rear of my 2026 Rubicon X to compensate for loads. Im going to have my dealership do it to avoid any warranty issues. I spoke to the suspension tech and he said no problem but make sure they can be stacked with the existing isolators which are also about 1/2 inch thick. If not and he installs them in place of the isolators id need a 1 inch spacer to achieve the desired lift. They would need to have a locating nub on the frame side to mate with the frame hole if using them alone. Can you advise?
Thanks
Bob K
To achieve a true 1/2" lift on your 2026 Rubicon X, the Teraflex 1155120 Rear 1/2" Coil Spacer Load Level Kit is the correct part, but its installation depends on whether you stack it or replace the factory components.
Stacking vs. Replacing
The Teraflex 1/2" Spacer is specifically designed to be stacked with your factory spring isolator.
How it works: You place the Teraflex spacer against the frame, and then fit the factory rubber isolator (which has the "locating nub") into the bottom of the Teraflex spacer.
The Result: Since you are adding 1/2" of material to the existing stack, you get exactly 1/2" of lift. This is the standard way to "level" a Jeep that is sagging due to a heavy rear bumper or gear.
The "Locating Nub" Requirement
If your tech wants to replace the factory isolator entirely (rather than stacking), the 1/2" Teraflex spacer will not work alone.
The Issue: The Teraflex 1/2" spacer is a flat puck. It does not have the integrated rubber "nub" required to index the spring and stay centered in the frame hole.
The Solution: If you go the replacement route, you would need a 1" Coil Spacer that features an integrated guide. However, most 1" spacers are also designed to be stacked.
Recommendation for Your Tech
Tell your tech that the Teraflex 1155120 is intended to be stacked on top of the factory isolator.
The factory isolator remains in contact with the spring (maintaining the "nub" alignment).
The Teraflex spacer sits between the isolator and the frame.
This setup is common, safe, and achieves your 1/2" lift goal without needing a 1" part.

Are they stackable or do they offer a 1 inch rear spacer For the JL ??
They are stackable
Abdullah A.
Could I put two of them in each right and left rear sides to make it 1 inch in each?
Yes, these can be stacked, but take into consideration the length of your shocks. These are intended to correct sag and trim when loaded with heavy accessories such as racks gear. If you are using to achieve lift over the stock height you may run short on the shocks.
