The SB-3 Beadlock wheels by System 3 Off-road are engineered for aggressive riding and punishing terrain. These beadlock wheels feature classic Baja styling and rugged modern construction. With a 10mm billet ring, 5/16-inch Grade 8 bolts, and a 1500-pound load rating, the SB-3 is the strongest cast UTV wheel on the market. The wheel's stainless steel lug inserts are an industry first for a UTV wheel; these inserts ensure a tight fit that won't go oval-shaped with use.
