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 kit is perfect for a 2025 Gladiator. Easy to install and did the job of leveling out the truck. I used the full 1.5" pucks. Super happy I did as it is exactly how I wanted it. This can be done with basic tools, torque wrench, 4 jack stands and a floor jack. Directions are spot on. Did not need to adjusted steering wheel or get an alignment after installing. Ride quality did not change, still rides and drives like stock.

Fairly easy install, sits the truck just about dead level. Highly recommend. Should have come this way from factory!

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

Did its job nicely. Bought it to fix the factory rake on my ‘24 Gladiator. Install took about 2 hours with a lift not rushing. Instructions were pretty solid. The bump stop extensions were probably the “hardest” part just trying to hold the bottom nut in place. Not a lot of room in there. Had to straighten the steering wheel after, but did not affect the alignment at all other than that. Still rides smooth. Great product, especially for the money. Definitely recommend if you’re looking to level out your gladiator or wrangler.
