Description
Mammoth Split 16 Beadlock Wheel. Mammoth's Split 16 Beadlock Wheel features a military inspired 8-spoke design with a inner ring that creates 16 individual windows. The simulated bead lock bolts around the outer lip adds to the wheels rugged good looks. A branded Mammoth center cap is included. This Mammoth Wheel is perfectly suited for street and off-road applications.
Satin Black Finish with Polished Lip. This Wheel is completed in a high quality, satin black finish with a polished lip for an impressive contrast in appearance that everyone will envy. For added protection and good looks, this Wheel features a durable clear coat that is tough enough to stand up against the hazards of everyday driving - including road chips and pitting.
One-Piece Cast Aluminum Construction. Mammoth's One-Piece aluminum Wheels are manufactured using gravity casting. Gravity casting is the process of pouring a molten aluminum alloy into a wheel mold or form utilizing the earth's own gravity to help fill the mold. The result is a strong, durable wheel that has the same good looks as a more expensive wheel, at a fraction of the price.
Application. This Mammoth Split 16 Beadlock Satin Black with Polished Lip 6-Lug Wheel; 20x9; -6mm Offset; 6 x 139.7mm (6 x 5.5-Inch) Bolt Pattern is designed to fit 2014-2018 Chevrolet Silverado 1500 models. Sold individually.
