The Metal FX Mayhem Beadlock in Gloss Black is a true beadlock UTV wheel for 4-lug Can-Am, Honda, Polaris, Kawasaki, Yamaha and Speed UTV machines, offered in 4x136/4x137 and 4x156 bolt patterns and in 15x8 and 15x10. It pairs a cast A356-T6 aluminum wheel with a forged 6061-T6 beadlock ring and an all-gloss-black finish that keeps the wheel and beadlock ring visually connected, with no machined silver accents.

Airing down for traction makes a tire more likely to roll off the bead. The Mayhem's beadlock ring clamps the outer bead to the wheel so it stays seated at lower pressure. Whether you are shopping 4x137 beadlock wheels for a Can-Am X3 or 4x156 beadlock wheels for a Polaris RZR, this Metal FX beadlock wheel comes in both patterns, so one design covers mixed-brand groups.

Among Metal FX wheels, the Mayhem sits in the Premium Cast range of Metal FX beadlock wheels. It covers 4x137 wheels for Can-Am and Honda and 4x156 wheels for Polaris, Kawasaki, Yamaha and Speed UTV, so riders comparing beadlock UTV wheels, Can-Am beadlock wheels or RZR beadlock wheels can run one design across machines. Choose the 15x8 beadlock wheels for a narrower stance or the 15x10 UTV wheels for a wider one; both are 4-lug beadlock wheels at +0mm offset. If you want black beadlock wheels, Gloss Black is the all-black choice.

Key Features

  • Functional beadlock: a forged 6061-T6 aluminum ring clamps the tire's outer bead
  • A356-T6 cast aluminum wheel (Metal FX Premium Cast line)
  • 4x136/4x137 or 4x156 4-lug bolt pattern, chosen by variant
  • 15x8 (+0mm, 4+4) and 15x10 (+0mm, 5+5) sizes
  • Gloss Black finish

Built To Solve: Tires Unseating at Low Pressure on 4-Lug UTVs

  • Tires rolling off the bead when aired down for sand, desert and rocks
  • Stock wheels with no beadlock hardware for low-pressure riding
  • Needing one wheel design in both 4x137 and 4x156 for a group that rides different brands
  • Picking a width without knowing the offset and backspacing
  • 5-lug Polaris RZR Pro R and Turbo R beadlock wheels that will not bolt onto a 4-lug RZR (those need the Mayhem R)

Best For: 4-Lug Can-Am, Polaris RZR and Honda Owners Who Air Down

  • Can-Am Maverick X3, Sport, Trail, Commander and Defender owners shopping 4x137 beadlock wheels
  • Polaris RZR, General and Ranger owners comparing RZR beadlock wheels in 4x156
  • Honda Talon 1000 and Pioneer 1000, Kawasaki Teryx KRX 1000 and Yamaha YXZ 1000R (2019+) owners
  • Riders comparing UTV beadlock wheels in 15x8 and 15x10
  • Builds that suit Gloss Black; for a different look, see the Gloss Black Contrast Cut or Gloss Silver Machined Mayhem
  • Polaris Pro R, Turbo R or Can-Am Maverick R owners should look at the Mayhem R (5-lug) or Mayhem 6R (6-lug) instead

Fitment

Metal FX sells the Mayhem Beadlock in two 4-lug bolt patterns. Wheels fit by bolt pattern rather than model year. Choose the variant that matches your machine:

  • 4x136/4x137 version (Metal FX: Can-Am / Honda): Can-Am Maverick X3, Maverick Sport, Maverick Trail, Commander and Defender; Honda Talon 1000 and Pioneer 1000
  • 4x156 version (Metal FX: Kawasaki / Polaris / Yamaha 2019+ / Speed): Polaris RZR (4-lug models), General and Ranger; Kawasaki Teryx KRX 1000; Yamaha YXZ 1000R and Wolverine RMAX (2019+); Speed UTV El Jefe, El Diablo and Baja Bandit

Not for 5-lug Polaris RZR Pro R, Turbo R, Pro S or Kawasaki Teryx H2, or for the 6-lug Can-Am Maverick R. Fitment is not guaranteed on applications not listed here; confirm your bolt pattern and overall vehicle width with your chosen tires before ordering.

FAQ

Will the Metal FX Mayhem Beadlock fit my UTV?

It fits by bolt pattern, not model year. Metal FX lists the 4x136/4x137 version for Can-Am and Honda, and the 4x156 version for Kawasaki, Polaris, Yamaha 2019+ and Speed UTV. Choose the variant that matches your machine's bolt pattern and confirm overall width with your tires.

Should I order 4x137 or 4x156?

Can-Am machines such as the Maverick X3, Maverick Sport and Trail, Commander and Defender, and the Honda Talon 1000 and Pioneer 1000, take the 4x136/4x137 version. Polaris RZR (4-lug models), General and Ranger, Kawasaki Teryx KRX 1000, Yamaha YXZ 1000R and Wolverine RMAX (2019+), and Speed UTV models take the 4x156 version.

What sizes, offsets and center bores are available?

In Gloss Black: 15x8 (+0mm, 4+4 backspacing) and 15x10 (+0mm, 5+5 backspacing). Center bore is 110.2mm on the 4x136/4x137 version and 132mm on the 4x156 version.

Is the Mayhem a true beadlock or a cosmetic ring?

It is a functional beadlock. A 6061-T6 forged aluminum ring mechanically clamps the tire's outer bead to the A356-T6 cast aluminum wheel, which helps keep the tire seated when you run lower tire pressure.

What lug nuts do I need, and is there anything to do before install?

Lug nuts are sold separately. Metal FX wheels take acorn-style lug nuts, and Metal FX, Valor or other acorn-style lug nuts in your machine's thread size all work. Metal FX also says to remove the mud scrapers before installing these wheels to avoid damage; their removal instructions are linked on this page.

How does the Gloss Black finish compare to the other Mayhem finishes?

The Mayhem Beadlock comes in Gloss Black, Gloss Black Contrast Cut and Gloss Silver Machined, with the same sizes, bolt patterns and construction. Gloss Black is the all-black option for blacked-out builds, or to let a bright body color stand out.

Why Metal FX

Metal FX Offroad builds its UTV wheels around specific bolt patterns: a 4-lug line, an R line for Polaris 5-lug platforms and a 6R line for the Can-Am Maverick R. The Mayhem Beadlock is part of the Premium Cast range, pairing a cast A356-T6 wheel with a forged 6061-T6 beadlock ring, and it is offered in three finishes so you can match your build.

Complete Your 4-Lug UTV Beadlock Wheel Setup

Pick your bolt pattern and width, then match a tire size and check overall width before you order the Mayhem Beadlock in Gloss Black. Add an acorn-style lug kit in the right thread for your machine, and plan to remove the mud scrapers at install using the Metal FX instructions.
