Quadratec Maximum Duty 3.5" Coil Spring Suspension Lift Kit Reviews
I installed this kit on a stock 2020 Jeep Gladiator Rubicon. The kit raised the front just over 4" and the rear around 2.5" which pretty much leveled it out. The ride quality is great...I'd say maybe a little stiffer than stock but overall I'm very satisfied with the ride. Ended up purchasing a set of front control arm relocation brackets from Rough Country and now all is good. If you order this kit I'd recommend getting the brackets and doing it all at once. I've driven the Jeep about 50 miles or so on various roads and speeds with no issues. Ran it up to 75 on the interstate with no issue.
My only concern with this lift is the shocks. I opted for the upgrade Nitro 8.0 shocks but they struggle to control 37x13.5" Toyos. I can feel them bounce once or twice when I hit a bump at higher speeds. I have some concerns with the shocks being too short as well. I had to jack the axles up to get them on which means they are the limiting stop for down travel. This may be normal for Jeep lifts but doesn't sound right to me.... Finally, the shocks come in a box with 'Hydro' on one side and 'Nitro' on the other. The shocks do not have stickers on them. Mine had both Hydro and Nitro stickers in the box allowing me to pick which I used so it makes me wander?????
I'm running 17"x10" wheels and I think they are -38 offset but not certain. They stick out of the stock fenders about 2" on each side. No scrubbing lock to lock but I haven't taken it off road yet.
It took me about 10 hours to install the lift with help. That is using a 2 pole vehicle lift. It would have taken me longer working on the ground with jacks. A heavy duty racket strap and a prybay will be your friends during the install.
4 stars mainly because of the shocks...
