Forgeline GS1-Truck

Based upon our original 5-lug GS1, the GS1-Truck is a 6-lug street-friendly version of our extremely successful GS1R racing wheel that has carried many top-level professional road racing teams to victory! The Forgeline GS1-Truck combines the latest in advanced wheel technology, including one piece forged monoblock construction, motorsport engineered design, and I-beamed spokes. And just like the GS1R, the GS1-Truck is engineered to withstand the rigors of top-level endurance racing with a 2100 lb. street tire load rating and exceptional deflection stiffness.

Though made from the same forgings and similar design as our race-winning GS1R (including the distinctive smooth chamfered outer edge), the GS1-Truck forgoes the GS1R’s aggressive open-lug center area for a more traditional (perhaps “gentlemanly”) center design that accommodates our standard press-in aluminum center cap. Perfect for 6-lug truck and SUV applications including the Cadillac Escalade, GMC Yukon, Chevrolet Tahoe, and Ford Expedition, as well as Ford and Chevy full-size pickups.

The GS1-Truck is machined from a single forging of 6061-T6 aluminum. It is currently available in 18, 19, 20, 21, and 22-inch diameters with a range of widths and offsets. (Please Note: Depending on size, the GS1-Truck may be available in deep, medium, or shallow concave profiles.) And just like any Forgeline wheel, the GS1-Truck is available with fully customizable finish options.
