      Mammoth Boulder beadlock style charcoal rims

      Absolutely love these, the pictures do not do justice for the color online. Not too fancy/flashy but exactly what I needed because I wasn't going to put wheel spacers on. Very close match to the Granite metallic crystal color of my JL Wrangler. I put on 315/70/17 Cooper Discoverer STT Pro

      These wheels look great ! The guy at the tire shop was really impressed with the new look of my JK. The wife was a little unsure of the style (she prefers shiny polished wheels) but when she saw them on the Jeep she said it looked tough.

      Review from Mammoth Boulder Black Wheel - 17x9 (07-18 Jeep Wrangler JK)

      Good for the money

      Quality of the wheels finish is not very good - one of them had a long hair that had been painted onto the wheel. When removed, it took some of the paint with it and left lines of raised paint where it used to be. I didn't contact ET about this, as I didn't care enough to ship it back and wait for a new one... it became my 5th wheel spare. Paint seems "soft" - already have my first chip, with no exciting 4x4 story to tell for it - just normal road use. Now, aside from all this - I get compliments everywhere I go, and everyone agrees they look badass.

      I picked the boulder wheels because I wanted to obtain that traditional jeep look, but still have an aggressive look. These achieved both. Still looks traditional, but very aggressive. Thank you Team Extreme Terrain.

      Review from Mammoth Boulder Charcoal Wheel - 17x9 (07-18 Jeep Wrangler JK)

      Thorough review

      I have a 2017 Sahara unlimited wrangler 4door. Products made it within a reasonable amount of time. Had to call to get my order to go through but probably do to who I was banking with so everything went great there and because I had ordered a couple thousand dollars of stuff I got about 200.00 off the overall purchase which I thought was thoughtful. I got four steel braided rear brake lines instead of two front and two rear but could of been my fault there so will be looking into that but they were very good quality. Overall very happy with the products. Only thing I will say is that the amount of time it took me to install it was about two hours longer than they had said but most likely because I didn’t have a car lift which would of made it way easier. That being said I got a rough country 2.5” lift without coils but came with the shocks and other hardware. Still braided lines and got 33” tires and new rims with TPMS sensors. Once I got them all to the right pressure I wanted it took about a mile before my ECU in the Jeep read them and everything worked fine so no going back to a shop to get them programmed. So worth it to have them do the sensors for the 60.00. I also had to drill one hole so be ready with a drill and I believe a 3/8 drill bit.. (can’t remember the size exactly). But it was easy enough. So if any of you read this and doing it yourself I would suggest getting some bigger jack stands (bigger than 6 ton) because of how far the axles drop. This will make it ten times easier when getting the coils out. And lastly probably a good idea to get some coil compressors (not sure that’s what they are called) because they helped me out when I couldn’t get the axles to drop all the way. Took me 6 hours to do all of it and it rides great and looks even better!!! Hope this helps everyone. Thanks for reading. Oh and it’s Thanksgiving today so Happy thanksgiving everyone!

      Great Wheel, Great Price

      In my search for a clean look for my Jeep at an affordable price tag I came across these wheels. The finish is not perfect if you look close, but from normal viewing distance they look great. The clean 5 spoke design looks great on the Wranglers and the Charcoal color looks perfect against my Orange JKU. I paired these with 285/75/17 RG's and a 2.5" JKS Jspec lift for a capable daily driver. I am very happy with these wheels and highly recommend Extreme Terrain.
