Works for 2025 Gladiator
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.

Quality leveling kit!
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.

Gladiator rake is gone
Used it to get rid of the rake on our 2020 Gladiator. Easy to install. Even the nut everyone says is a pain went super easy. Use their supplied tool to come straight up from the bottom not from the side. Took care of the rake and looks awesome

Jeep Gladiator Rubicon
Install was very easy, definitely helps having a second hand, makes it quicker. It took only an hour start to finish. Definitely follow the directions on reinstalling the track bar. Do it on the ground rather than muscling it back into place while it’s jacked. All you have to do is turn the wheel and it will line back up. Definitely leveled the Jeep out. For my Jeep it did not throw off the alignment surprisingly, still tracks straight and the ride still feels stock. Update. Added 35’s and did few trips with the kit installed. The jeep still performed well and definitely notice the extra ground clearance with the 1.5 plus adding 35’s.

Overall great leveling kit, though I might suggest a few changes to make it better.
Just what you need if you want to level out the factory rake on a gladiator. It’s a bit harder than I expected it to be to lift the truck high enough on the jack stands to get the axle low enough to take the springs out. This won’t be a problem with a vehicle lift, but if you are working on the garage floor you really need to get the truck up to the 4th or 5th notch on a standard jack stands. The instructions are actually pretty good and if you follow them, you will be good. Note that some of the torque specs for the suspension bolts are nuts. I only have an 80lb torque wrench so everything that called for more than 80lbs of torque got the uggah duggah machine on full beans. My dewalt 3/8’ impact gun got everything off pretty easily. I would suggest that you have more than one jack. If you put one jack under each front axel you should be able to easily raise and lower each side of the suspension when you start to put everything back together. It helps a ton with lining things back up. Follow the instructions and wait until the truck is back on the ground before you reinstall the track bar bolt. You can use the jack to slightly raise or lower the suspension on one side to help line up the bolt. On the bad side, the provided wrench for holding the nut when installing the bump stop extensions is terrible. It’s so hard to hold in place, especially on the passenger side. It probably took me 20mins to tighten that one bolt down. The driver side is easier as there is less interference. Also, you might wait a step or two to take off the breather hose on the axle. There wasn’t enough room for me to get pliers in there until I lowered the axel a bit.

Better than expected
Was hoping to get rid of the factory “rake” in the front. I was hesitant to only go with the 1.5” leveling kit, but after reading what others said, I gave it a shot. I was pleasantly surprised at how nice it turned out, really changed the appearance of my Gladiator. Easy to install (easier if you have two floor jacks) Just look for the installation video with the girl on YouTube. Her instructions are near spot on. The only issue I had was with the “special “ Wrench for the lower spring stop. The wrench does not work on the passenger side. Go buy yourself an offset 14mm at Harbor Freight.

Does fit 2024 gladiators
Even though it says it doesn’t, it will fit a 2024 gladiator. Easy installation leveled my Rubicon perfectly.
