      Description

      Increases Clearance. If you're running stock size wheels with a wider set of tires you may encounter inner wheel rub. Installing a set of Mammoth Wheel Spacers will increase clearance to prevent this rubbing. As an added bonus these Mammoth Spacers will set your wheels out an additional 38.1mm (1.5 Inches) giving your truck a rugged stance getting rid of that wimpy tucked in look.

      High Quality Construction. These Mammoth Wheel Spacers are manufactured from CNC-machined aircraft quality, 6061-T6 billet aluminum alloy for superior strength and durability. The Spacers are then completed in a durable corrosion resistance black anodized finish for impressive good looks.

      Application. These Mammoth 1.50-Inch Wheel Spacers are designed to fit 2015-2025 GMC Sierra 2500 HD models equipped with factory, or aftermarket wheels that have a 8 x 180mm (8 x 7.08661-Inch) bolt pattern. Sold as a set of two spacers.

      Please Note. (16) Spacer Lug Nuts are included, but you will still be required to use your original lug nuts for installation.

      Awesome!!

      Very happy with these wheel spacers. Gives my ranger and wider more aggressive stance. I added ready lift crash/intrusion bars because my 285/70 17 tires rubbed the old intrusion bars. Time to install more than an hour less than an afternoon for me

      Excellent Spacers!!!!

      These spacer have a precision fit on both the hub and wheel. The wheels fit very securely and don't get stuck on when trying to remove them.

      Good wheels once balanced

      One of the wheels came bent from the manufacturer. I had to have the body shop balance the wheel in order for it to be installed. Considering the other 3 were fine I doubt it was damage due to delivery and handling.

      Looks amazing

      Zero complaints with this tires and rims package. Chevy quoted me 1000 for just stock tires. Couldn’t beat this offer for the package and they look amazing
