Halibrand 5 Spoke for the Square-Body C10 are a nostalgic styled wheel based on original Halibrand design, but updated to fit modern tire sizes and modern tapered seat lug nuts. They were engineered specifically for the C10 Square-Body fleet side trucks with proven fitment, tire clearance, and backspacing optimized to fill up the wheel openings. These wheels eliminate the fitment guesswork & tire rubbing that can be common with generic-sized after-market wheels. The Flow-Formed wheel manufacturing process applies pressure and heat to the wheel casting while it is spinning to stretch and compress the aluminum. The finished wheel is lighter, stronger, and features a higher shock resistance and load capacity compared to a standard cast aluminum wheel. Wheels are available with a painted Anthracite finish or fully polished. The 3-step paint process includes a powder-coated primer, paint, and clear-coat for durability and easy maintenance.
