## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect Fit with the Correct Lugs
*by B***H on May 21, 2020*

These wheels work perfect and look great on my 2018 RZR 900 trail. As mentioned by others, the lug nuts are not the correct ones for a RZR. The wheels do require a small diameter lug. I just went down to my local Discount Tire and picked up a set of Grizzly small diameter lugs with the correct thread. Easy fix, but will run you an extra $45 or so.

### ⭐⭐⭐⭐ Can’t find the lugs
*by T***R on October 16, 2020*

Hey man I got my package it says lug nuts are inside never found them any tips on what to do in my situation but besides that there some good rims for the money

### ⭐⭐⭐⭐⭐ Great looking Rim and a great value
*by S***. on July 6, 2021*

Rims look great on my 2017 RZR 570. Super fast shipping came with Lugnuts.Such a great value for such a nice looking rim.They survived two days at Rush off-road in Kentucky and seem like they’re going to be nice rims
