MSA M21 Lok ATV Wheels/Rims Gunmetal 15" Sportsman RZR Ranger



Availability: In stock




The M21 Lok is beauty, function and performance all engineered to push your machine to the next level. Each M21 Lok wheel some 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. The unique Lok wheel design sheds weight, dirt, mud and debri fast making clean up a snap. (Depending on the machine your stock lug nuts may not work with this wheel. They MAY require a different style lug nut that we offer) Center cap included.

When you buy a set of 4 wheels OR 4 wheels & tires from us we include a Chrome Lug Kit at no additional charge ($32 Savings).

Beware of other companies that do not include lug nuts & valve stems with their wheel sale, some wheels require a special type of lug nut to fit into the wheel and your stock lug nuts may not work.
