    I have a 91 yj Sahara with a stock front end that has a 4 inch lift. Will I need to modify it to accept 33x12.5's (Hub Spacers) for turning radius clearances?

      Very Happy

      I've had these on my 2004 LJ for about 4 months and I'm very pleased with them. They look great and the finish has held up well so far. I've been hitting moderate/rocky trails weekly since putting them on and have zero scratches in the finish so far. The charcoal color is a very close match to my new Trektop NX. That's why I went with the charcoal color over black and I'm really happy with the decision.

      Poor Paint Finish.

      Unfortunately the paint was chipped off the wheel around the center caps. I went to switch them too yellow caps i purchased and the paint flaked off even worse.

      Great look, paint isn’t durable though

      Great looking wheel, I paired it with 33” tires. The only drawback I have found is that it’s described as an off-road wheel, yet mine have pealed paint just from the mounting and balancing process. When balanced, the machine pressed the front of the hub with a rubber press, and the rim around the hub shows white now vs the painted charcoal. So the wheel looks great initially, but would be better with a more durable paint, or powder coating.

      Perfect fit can form and finish.

      I was concerned about the off set/back spacing of the wheel when shopping for new wheels. These are a perfect fit for mounting 33-12.50-15.

      Mammoth Beadlocks

      Good looking wheels! Paired with 32x11.5x15 tires on a stock jeep. No issues.. They stick out 3 inches past the stock fender flares giving more clearance on the inside... No rubbing.. took forever to receive them, but i was compensated for it. Good product!!

      I am very pleased with the wheels. I was looking for hubcentric wheels for the Jeep that were a combination of stylish and affordable. These fit the bill well. The grey colored ones accent my Jeep's silver paint well.

      Great for the money

      Installed these on a 2000 Jeep TJ. Due to shipping one wheel came with a ding on the stainless lip. ET customer service made it right and I'm a happy camper. These look great especially with the yellow centers. Be careful with the powder coat, I think it's a little thin.
