Wheel model

Fast HD Mammoth

The Mammoth is a model in the Fast HD lineup designed for muscular-looking trucks and SUVs. It's produced in gravity-cast monobloc aluminum, ensuring ruggedness at a controlled cost for pickup applications. Its bold spoke design and evocative name make it suited to full-size vehicles, including lifted ones or those fitted with wider tires. This type of wheel comes in diameters of about 17 to 20 inches, in 6- and 8-lug configurations (bolt patterns like 6x139.7, 8x165.1 or 8x170 depending on the application) and with offsets that are sometimes negative for an aggressive look and increased clearance. The matte black or machined finish reinforces the off-road appearance. Like the entire HD segment, the Mammoth favors durability and price over lightweight construction. In Quebec, validate the precise bolt pattern, center bore, the load rating needed for towing and brake clearance; a dark finish requires regular anti-salt maintenance in winter.
