    Great wheels and they fit DynaTrac ProGrip Brakes

    I've had a set of 17 inch Mammoth Boulder Black wheels on my 2017 JKU for 12 months and they're fantastic. Even better, I can confirm fitment with DynaTrac's ProGrip brake system. Even with tape weights, there is enough clearance for everything work work perfectly.

    Very nice

    These wheels shipped very fast and the packaging was in good condition. They look every better in person and look like good, quality, cast wheels. There aren’t many options for 16” wheels but these are perfect. I plan on putting them on Cooper St maxx
