Product Review: 1 Inch Polyurethane Lift Kit for Jeep Wrangler JK

This is a product review for a 1 Inch Lift Kit for Jeep Wrangler JK from Rukse, or other vendors as they are all pretty much the same product. We got the product at a discount and not persuaded to do a review on it. The review is after about 1 year after installation of the product.

1 Inch Lift Kit for Jeep Wrangler JK from Rukse a Product Review

The above photo is of the Jeep Wrangler JK Sahara edition that we will install a 1″ lift kit on. Right now it has 18″ rims and stock Goodyear tires. We wanted to put a 305/70R/18 tire underneath it but would not be able to with the stock lift and current fender flares on it.

We didn’t want to go with a 2″ lift kit because it would be to much height and if we went that big we felt it would be wiser to go with new coil springs.

So we picked out the Maxxis brand Bighorn tire, and we got a good deal from 4WP and had them installed after we put on the lift. The tires themselves have held up very well with their mileage guarantee and will probably fall right into the 40,000 mile limit.

They wore very even and I had not issues with them. We did get a screw puncture in one of the tires, but Discount Tire fixed it for free even though we did not buy our tires from them. They are really great.

So here is a photo of the 1 inch lift kit installed with the new tires installed. Notice how much clearance we have with the Bushwacker Flat Fender flares, and the small lift. The problem though is we used the stock rims, and did not go with aftermarket rims. So there is some rubbing on full lock turns so we have to be careful doing that.

The reason we did this was we did not want to order aftermarket rims in an 18 inch size. Tires for this rim are very expensive. And we can order 16″ rims and new tires for the same price of just the tire in an 18 inch size.

This is the rear view of the 1 inch lift installed with the larger tires. I do not like the look of all the space between the top of the tire and the flare. But we took out the fender shield that would have blacked that out a little. This problem should be remedied when we get the newer tires.


So this is a photo of the 1 Inch Lift Kit for Jeep Wrangler JK which is made by Rukse, out of high durometer polyurethane. When we got the kit, it was very solid, and heavy. The parts seemed very well made with a smooth finish and perfectly molded seats for the coil springs. I was pretty impressed by the look of them.

But looks are nothing in the 4wd world, especially for suspension parts. What matters is that they work well and last forever.

The Installation of the 1 Inch Lift Kit for Jeep Wrangler JK

The installation of this product was quick and fairly easy. It took us about 2 hours to do the front and rear. We had a jack, stands, a socket and wrench set and a rubber hammer. That was it. Removal of the tires and wheel is first. On the front we jacked one side up and did each side one at a time.

We put the opposite side on jack stands so we could raise and lower the other side with the jack, this allowed us to remove the coil spring. We then removed the bottom of the shock, and the bottom of the sway bar end link and allowed the item to drop.

Keep an eye out on the brake lines that you dont stretch them to far, if they are going to stretch you need to remove the clamp that holds them to the frame.

Once you get that done you should be able to lower the axle enough to get the coil spring out and put the new spacer on top and reinstall the spring. You may need to use the hammer a bit to get it back into place.

You can reuse the stock isolator to get maximum lift. Then we buttoned it all back together in the opposite way we took parts off and put the tire and wheels back on and removed all the jack stands and moved to the rear.

We did the same for the rear although it was a little harder to get the coil springs out. We did have to remove the brake line clamp that held them to the frame. Also the rear sway bar is a little tricky to maneuver back there so if you remove the sway bar clamps like we did to get some clearance it can be a little difficult to realign when done.

We also removed the end link bolts and the bottom shock bolts. We had to use more hammer and muscle to get these back in but we did with some muscle. Coil spring compressors would help out for the rear.

Once we buttoned the rear up, and re-tightened everything to correct torque specifications we checked to make sure the suspension coils were seated correctly on the spacers, they were not bulging anywhere and the axles were centered.

Everything looked good so we took it out for a test drive and made sure everything tracked smoothly and there were not steering issues. Once we got it back in the ship we re-checked the bolts and made sure everything was tight. We re-checked after 100 miles to be sure.

All in all this product was very easy to install, even if you do not have any previous experience installing a lift kit. Wear some gloves to protect your hands as taking off some bolts can be tough. After a year of using the product they have lasted with no splitting of the spacers, no bulging, and more importantly no sagging that I can see. We give this product a solid 4 out of 5 stars. The only downside is that the ride can be a little rougher with spacers and they do take some time to install.
