Metal FX® Mayhem 15" UTV Beadlock Wheel: 4x136/4x156 | Gloss Black

Metal FX Mayhem Beadlock UTV Wheel

Mayhem Comes to 4-Lug.

The Mayhem beadlock already came in 5-lug (Mayhem R) and 6-lug (Mayhem 6R) versions. This 4-lug Mayhem in Gloss Black brings the same design to Can-Am, Honda, Polaris, Kawasaki and Yamaha 4-lug hubs, with the ring and wheel both finished in gloss black.

Both widths sit at +0mm, with 4+4 backspacing on the 15x8 and 5+5 on the 15x10, in 4x136/4x137 or 4x156. Metal FX rates the 4-lug Mayhem at 1,600 lbs per wheel, higher than the 1,260 lbs it lists for the Mayhem R and 6R.

Each Mayhem wheel in Gloss Black is A356-T6 cast aluminum with a 6061-T6 forged aluminum beadlock ring. Metal FX does not currently publish a weight for this finish. Center caps for this finish are part 10329. The matching replacement beadlock ring is part 10258.

Features and Benefits

• True Beadlock: A 6061-T6 forged ring clamps the outer bead so you can air down with less risk of losing the bead.
• 1,600 lb Rating: The highest load rating Metal FX lists for any Mayhem.

Mayhem Gloss Black Specifications

PLEASE NOTE: Single wheel purchase only, tire and extra vehicle accessories NOT included! Double-check your machine's bolt pattern, offset, and fitment clearances before ordering to ensure absolute accuracy.

Important Fitment & Legal Notes

• Off-Road Use Only: Metal FX builds its beadlock wheels for dedicated off-road use. Beadlock wheels are not legal on public roads in many states and provinces, so check your local laws before you ride.
• Beadlock Maintenance: Torque the beadlock ring bolts to Metal FX's specification when the tire is mounted, then recheck them after the first few rides and after any hard hit. Mounting a beadlock takes longer than a standard wheel, so use a shop experienced with beadlocks if you aren't set up for it.
• Lug Nuts Required: These wheels require aftermarket lug nuts (sold separately).
• Remove Mud Scrapers: Before installing, remove your machine's factory mud scrapers to avoid damaging the wheels. Metal FX publishes removal instructions.
• Construction: A356-T6 cast aluminum wheel with a 6061-T6 forged aluminum beadlock ring.
• Warranty: Covered by Metal FX's One-Year Limited Structural manufacturer warranty: one year against material defects and 30 days against workmanship defects from the date of receipt. Beadlock rings are not covered, and bent or cosmetically damaged wheels are excluded.

UTV Application Warning: Customers and/or users are responsible for ensuring that this product is compatible with their machines as currently configured. Professional installation of beadlock hardware is highly recommended, and routine safety inspections on the beadlock ring torque specs are required before trail usage.
