Reviews for Quadratec Maximum Duty 2.5" Coil Spring Suspension Lift Kit for 97-06 Jeep Wrangler TJ

Delivered as described. Installed in 4 hours​ on my 2003 Jeep Wrangler freedom edition with no problem. 2 1\2 lift with 18" rims and tires was the perfect combination and I get alot of compliments how good it looks.

I was looking for a best bang for the buck 2.5 lift and found it with this offering. I had it installed at a local shop and am very pleased with the results. I got the Nitro shocks and it rides nice on my 2005 Unlimited. I can't wait to get back to Arizona and the Jeep trails. Shop said they had no problems on the install.

Finished my lift this morning. Took about 7-8 hours total with one Autozone run and a few beer breaks. Before I started I took measurements to the bottom of both bumpers and reevaluated the clearance after it was finished. 2.5 exactly. Rides great and was the perfect tasteful lift for my jeep. The 31s look perfect under it now. I would suggest soaking everything down in PB Blaster at least once a day for a week prior to insulation. Also, replace the steering stabilizer while you are at it. It was a decently easy install with three guys in a fully functional race shop. Probably too much for someone to do at their house with basic tools, but it wouldn't stop me from trying. Overall very satisfied. Great quality and great service.

For the money, I feel like this product cant be beat! It gave my jeep the perfect amount of lift and the desired look I was after. All the parts and instruction booklet that came with this purchase were of good quality. The lift seemed to soften the ride and gave my jeep approx. 3" of lift. The lift went on fairly easy. Ill have to second the comment about needed to soak EVERYTHING in PB Blaster, its a definite must. I will admit after the lift was installed I got a high frequency vibration at 40+mph. After taking to a local mechanic he discovered and explained that my drive shaft's angle had been altered and offered a quick fix solution of placing a spacer on the transition reducing the angle which got rid of the vibration. Other than that, I have nothing negative to say about this product, I recommend this product to anyone after a quick and easy lift.

Installing the lift kit took me a full day. It probably could have went faster if I had soaked the bolts a few days before with PB Blaster. Overall though the lift went on easy enough. The instructions were pretty good and had some helpful tips on the installation. The kit lifted my Jeep about 3-1/2" or so because the old springs were sagging so much. The 31x10.5's fit well and don't rub on the fenders in off camber situations. I ordered the Nitro Shocks with my kit so the ride is a bit stiffer but still well worth the time and effort. Be sure to get your Jeep aligned after installing the lift. I would recommend this kit for anyone looking for a 2-1/2" lift.

Great lift kit

Love the lift. It took a friend and I about 7 hours to put it in. it is challenging but not too bad if you know what you’re doing. I love how it looks. Only reason i don’t give it a 5 star is because The nitro shocks, the ones I ordered, are very stiff on the road but they are great off road. It’s bearable but I’ve heard the hydro would be more comfortable on road. I would recommend buying hydro unless you spend more time off road then on road.

Honestly a super nice lift kit. I run 33” tires with no rubbing issues. I would give this kit a 5 star rating but the only reason I knock it is because it gives you cam bolts to adjust the pinion angle, they are a pain to install and didn’t even fix the pinion enough to stop any driveline vibrations. I ended up just buying adjustable upper and lower control arms to adjust the pinion. Other than that though, I got the nitro shocks and it does ride rough, which is a given when you choose nitro shocks, but compared to other nitro shocks I’ve owned it by far is a lot smoother than the other ones I owned. Everything is really built well and it’s a really nice kit. It took me about a total of 7 hours to completly install, about 2 hours of that devoted to just the cam bolts installation. Also, a little tip is that when you are installing the front springs don’t bother trying to disconnect the control arms, it saves a lot of time to just rent some spring compressors from your local auto parts store.

This lift kit looks great on my 2006 TJ. It took a couple days installing by myself in my garage with basic tools. I used a spring compressor and didn't have to disconnect the lower control arms. The T55 on the rear is difficult getting off because there isn't enough room to use an air impact. Even the t55 socket I had was too long with the gas tank in the way. I used 2 cans of PB blaster and coated everything a few days in advance, several times. I still snapped off all 4 rear upper shock bolts. I ended up mounting the rear upper shocks to the frame which ended up being about 1 inch lower than the original location. The jeep seems to ride good, maybe even better than stock. I got the hydro shocks. They items shipped fast and nothing was missing. Now I just have to decide which wheels and tires to get.

I bought the kit with the nitro shocks. Love the springs and love the shocks. Overall, I am very pleased with the kit and the price. I would recommend this to a friend. I would also recommend a couple of additions however. I discovered after taking the suspension apart, that the bump stop cups on my old TJ were virtually rusted away. No way to use the replacement bump stops that came with the kit. They finally came in after months on back order. I will have to take the springs out again to replace them. They would be a cheap but useful addition to the kit. I can't be the only TJ owner whose got rust issues. Also, you will very likely need a new front track bar. After the lift, my front axle as off center just enough to be an issue. No big deal.
