SuperATV 1" Wheel Spacers for 4/156 Bolt Patterns with M12x1.25 Wheel Studs | Kawasaki KRX 1000 / Mule Pro FXT/FX/DX/DXT/FXR (See Fitment) | 2 Wheel Spacers | Heavy-duty 6061 Billet Aluminum

Allowed me to use a set of KRX 1000 15 inch tires and wheels on my Rmax 4. Fit great and worked perfectly. Gained almost 2 inches of overall width even though the 31x10x15 tires were an inch narrower than the stock 11 inch wide rear tires. Hub centric design centered up the KRX wheels perfectly. Won’t work with a lug centric wheel with a flat mounting surface, the KRX wheels have a recessed center that the ridge at the center of the spacer fits into.

These bolted onto the KRX's wheel hubs just fine, but it was a real effort to get the wheels mounted to the spacers. The bolt pattern seems to be a tiny bit off, and they seemed like possibly the wheel studs coming out of the spacers weren't 100% perpendicular to the surface of the wheel spacer. When I went to mount my rims and tires, the rim didn't want to go on. It's as if the studs in the spacer were spaced out too far, so I really had to muscle it over the first handful of stud threads, and it was scraping the stud holes in my wheels too. After I got the wheels on about 1/2", I was able to give them a stiff kick and that pushed the wheel further onto the spacer studs, enough so that the binding portion was cleared. But I'm really afraid of how hard it is going to be to remove the wheels from these spacers when I need to do maintenance. The studs in the stock hubs do not bind like the ones in these wheel spacers. This stuff is all built by robots so they should all be the same. I wonder if others have also had issues mounting the wheels to the spacers.Other than the slight fitment issue, they seem really nice. Super solid feeling and quite heavy duty. They came with the tapered lug nuts that are used to mount the spacer to the wheel hub. You will need to reuse the existing nuts and washers to mount your wheels to the spacers.Would recommend to others, but I'd also mention the caveat with the stud spacing being potentially off a smidge. We'll see what's it like when I have to pull the wheels off again. Hopefully things would have settled and it won't be such a tight fit.

Nice fabrication. One had a bent lug bolt which doesn’t allow the wheel to be installed on it. I’m guessing this happened in shipping. It will be easier to fix myself than return. Overall good purchase but careless shipping. Would recommend the product.

Description says this fits rmax4. Had this installed and wheels were wobbling. Removed spacers and tires worked fine. Super atv said these did not fit my bike, even though description says they do.
