Overview
Forgeline Drag Racing Series GS1 Beadlock Custom-Order Wheels
After more than 25 years of producing the most highly regarded and technically advanced wheels for professional road racing applications, Forgeline has directed their experience and capability toward the drag racing industry and developed the all-forged GS1 Beadlock wheel.
Unlike most traditional drag racing wheels, Forgeline's Drag Racing Series GS1 Beadlock carved entirely in one-piece from a single forging of 6061-T6 aluminum using an advanced precision machining process. This forged monoblock technology has proven successful, for many years, at the highest levels of road racing, and Forgeline is excited to apply it to beadlock wheels for straight line racing applications.
The GS1 Beadlock wheel is very similar to Forgeline's track-proven GS1R road racing wheel with one big exception: It has been re-engineered to include a special bolt-on outboard beadlock ring that, like the wheel itself, is also precision-machined from forged 6061-T6 aluminum. This forged aluminum ring holds the tire securely in place, to limit unwanted tire slip against the wheel, and to keep the tire from unseating, at very high speeds. The forged beadlock ring is secured to the wheel with a series of 21 standard lightweight titanium bolts. The GS1 Beadlock also forgoes the GS1R's aggressive open-lug hub center area for a more traditional hub center design that accommodates our standard press-in aluminum center cap.
Like all Forgeline wheels, the one-piece forged monoblock GS1 Beadlock is custom made-to-order for each individual customer and each unique vehicle application, and is offered in 17-inch, 18-inch, and 19-inch diameters in a range of widths and custom offsets and fitments. Upon request, it can be engineered to work with shank-style lug nuts. And just like any Forgeline wheel, the GS1 Beadlock is available with fully customizable finish options.
Customer must complete the Instruction sheet attachment for all wheel and related component information before a final price and availability can be provided. Finished price and availability will depend on the final configuration.
Non-Returnable; each custom wheel is made-to-order. As mentioned, the price will vary depending on size selected and the chosen options. Achieve the look and fit you're after with the Forgeline custom wheel for your ride.
All custom-order wheels are Special Order and Non-Returnable.
