The M21 Lok is beauty, function and performance all engineered to push your machine to the next level. Each M21 Lok wheel comes with all of the necessary parts to professionally lock any tire to your wheels to ensure a safe and quality ride. What makes this beadlock UTV wheel different from the rest is because of a couple unique MSA attributes. The finish we used on this wheel we are calling gunmetal which is actually a dart tinted clear-coat that is overlaid on top of the micro-machined wheel face adding depth, charcoal highlights and a completely new industry option. The Gunmetal finish is accented with gloss black automotive grade paint, only offered by MSA Wheels and currently only offered on the M21 Lok in this combination. We came out with the M16 Vice beadlock UTV wheel a couple of years ago and was instantly a success. We knew we had to up the ante so we increased the diameter and went with a full faced 15×7? option on the new M21 Lok, allowing you more tire options for your unique terrain. The unique Lok wheel design sheds weight, dirt, mud and debri fast making clean up a snap. We recommend you mount a set of EFX Tires which are tested tough and held to the same high standards as our wheels. Check out the EFX Tires page for sizing options.
