KM451 MESA FORGED MONOBLOCK
KMC KM451 MESA FORGED MONOBLOCK: Heavy-Duty 8-Lug Wheel
The KMC KM451 Mesa Forged Monoblock is a monoblock truck wheel built for full-size, heavy-duty 8-lug rigs. Its deep, split-spoke face carries a rugged, purpose-built look that suits lifted and stock-height trucks alike, and the single-piece monoblock design gives it the clean, structural profile that fits work trucks and overland builds equally well. It sits within the wider KMC lineup as the non-beadlock counterpart to the Mesa Forged family.
Sizes and fitments we stock
The KM451 is stocked in a focused 18x9 footprint, giving you a tall sidewall option on 8-lug applications. Three offsets are available to dial in stance and clearance: -12, 0 and +18. The -12 pushes the face outward for a wider track, 0 sits neutral, and +18 tucks it in tighter for trucks that need to clear suspension and brakes.
Bolt patterns cover the common heavy-duty 8-lug specs: 8x165.1, 8x170 and 8x180. Concrete examples in stock include the 8x165.1 18x9 +0, the aggressive 8x165.1 18x9 -12, the tucked 8x165.1 18x9 +18, and the 8x170 18x9 -12 for the Ford Super Duty crowd.

Finishes
The KM451 comes in Raw Machined, Metallic Blue and Satin Black. The Satin Black keeps things blacked-out and low-key, while Metallic Blue adds color to a build. Browse related shades across black KMC wheels, blue KMC wheels and silver KMC wheels.
Price and who it suits
The KM451 runs from $699 to $850 per wheel depending on offset and bolt pattern. It suits owners of 8-lug trucks and SUVs who want a monoblock wheel with real presence and multiple offset choices. If you want the same Mesa look with a locking ring for off-road airing-down, the KM444 Mesa Forged Beadlock covers that, and the KM446 Mesa Forged Monoblock is a close sibling in the same family. For a different face, the KM445 Impact Forged Beadlock goes more aggressive, the KM301 Turbine takes a directional turbine spoke, and the street-minded KM102 Signal works on lighter setups. Financing is available through Affirm, Katapult, Klarna, PayPal Credit and Snap Finance at checkout.
