TeraFlex 1155300 JT: 1.5” Performance Spacer Leveling Kit – No Shock Absorbers

I am not a mechanic but I like to do as much as I can by myself, so I decided to order this leveling kit and give it a try. I have followed the instructions, and I was able to proceed with the installation. You would need a torque wrench and a torque angle gauge. I didn’t want to rush it, and I was cautious at every steps, it took me 3hrs, in my driveway. But I have no doubt it can be done faster than that, however this isn’t a race. I have drove 500km since the installation, so far no issue, I have re-torqued everything as indicated in the instructions. Good product, not very complicated to install, good price.

This fit perfectly on JT front coil, The kit came with 2x0.5" and 2x1.0" spacer, you can choose to install 0.5" lift, or 1.0" lift or 1.5" lift (by stack them together). Install is fairly straight forward on my driveway. The instruction on teraflex is rather complicated asking you to disconnect the entire front end. I installed by by using 2 jack stands and a floor jack, the trick is to do one side at a time with the tyre remain on THE OTHER SIDE so the axle only drops on the working side, this allows the spring to be removed (I did use a set of spring compressor to clamp the coil down a bit for easy removal). the electrical connector to the front locker also needs to be disconnected to allow the axle to drop further.

Great leveling kit with well detailed instructions. Install took me about an hour. Even a diy guy with mediocre mechanical skill can do this in his driveway in under 2hrs. I’d recommend against purchasing other kits that are copies, this one is built to last and terraflex has a long reputation of making good products. I will say if you install the 1” and .5” spacer in the front you’ll want to get a 3/4 leveling kit for the rear especially if you haul a lot in the bed. As you can see in the picture my jeep now sets a little low in the rear with around 200lbs of cargo.

I installed the full 1 1/2" spacer set in the front of my Gladiator to allow for a bit more room up front and a bit larger tire. Most people say they can run 35's with this set and I do believe it, but I went with 33's for now, maybe bigger next set of tires. The installation was very doable with basic tools, and I did do a alignment after the install but the only thing out was the camber as it did lift the vehicle. Very pleased with it and I wouldn't hesitate buying more terra flex products in the future

First off the quality of the spacers for what you pay is phenomenal, especially from a reputable brand like teraflex. Easily worth the $120 to make your gladiator sit level. Everything fit perfectly and went on without any form of issue. While it did come with a tool to hold the bottom nut on the new bump stop it did not come with an Allen key for the bolt so just be sure you have one laying around. Instructions say it takes about 2 to 3 hours to do I was able to finish it in just about an hour. All I had to do was jack up the front of the gladiator remove the bolt holding the brake line bracket on the frame (Both sides) unbolt the bottom of the shock ( both sides), and lower the axle down till I can easily slide the spring off and put the spacer and reinstall the spring.
