Raceline A91B Ryno Beadlock UTV/ATV Wheel - Satin Black

The Raceline A91B Ryno Beadlock is a true bolt-on beadlock UTV and ATV wheel in satin black with a black beadlock ring, cast from heavy-duty A356 aluminum with a forged 6061 ring, and offered in 14x7, 15x7, and 15x10 sizes for 4/137 and 4/156 bolt patterns; base part number A91B-51056-55 is the 15x10, 4/156, 5+5 (0 mm offset) variant. It fits any UTV or ATV whose factory bolt pattern matches, rather than a specific vehicle list.

The Ryno's split 10-spoke design with offset spokes gives a modern, aggressive look, and Raceline engineers it as one of the strongest wheels in its lineup. Because this is a true beadlock — not a beadlock-style cosmetic ring — the forged 6061 outer ring physically clamps the tire's outer bead to the wheel with US-made Grade 8 zinc hardware, so you can air down for traction in rocks, sand, and dunes without rolling a bead. For tires with extra-thick beads, Raceline offers beadlock ring spacers separately to ensure proper ring seating.

Fitment & Compatibility

The A91B Ryno Beadlock is universal by bolt pattern: it fits any UTV or ATV that uses a 4/137 or 4/156 bolt pattern in one of the sizes above. The 4/156 pattern is the common pattern on most late-model Polaris models, while 4/137 is the common pattern on Can-Am and several other machines — always match the bolt pattern stamped in your owner's manual or measured on your hubs. Distributor catalogs list the wide 15x10 (5+5) as a rear fitment, typically paired with the 15x7 (5+2) Ryno up front. Does not fit machines that use 4/110, 4/115, or automotive 5-lug or 6-lug bolt patterns — the A91B Ryno is offered in 4/137 and 4/156 only. Verify width, offset, and tire clearance against your suspension and brakes before ordering.
