Weld S90471163P43 Ventura Beadlock Drag Milled 17x11 Rear for C5/C6/C7 Z06

Vehicle Fitment

• 2006-2013 Chevrolet Corvette C6 Z06 / Grand Sport / ZR1 (RWD) - Rear Only
• 2014-2019 Chevrolet Corvette C7 Z06 / Grand Sport / ZR1 (RWD) - Rear Only
• 2001-2004 Chevrolet Corvette C5 Z06 (RWD) - Rear Only

Fitment Notes

• Designed for REAR fitment only - a separate front drag wheel is required for a complete drag setup.
• Does NOT fit C6/C7 Base or Z51 models at this offset - Base and Z51 applications require the 18x10.5 +56mm variant.
• Beadlock ring hardware must be torqued to Weld's specified value and re-checked after the first heat cycle and periodically thereafter.
• SFI 15.1 and 15.2 certified - verify with your sanctioning body for compliance at your specific race class.
• Valve stem and TPMS sensors are not included; source separately.
• Conical seat lug nuts are required - OEM Corvette lug nuts are not compatible with this wheel.

Features

• True functional beadlock with a 6061-T6 aluminum scalloped ring and Heli-Coil thread inserts for secure, torque-verified clamping under drag-launch stress.
• Inner and outer barrel knurling mechanically grips the tire bead, preventing rotation or slip during high-horsepower launches.
• Rotary-formed flow-formed barrel monoblock construction delivers increased barrel strength at reduced weight versus standard cast wheels.
• SFI 15.1 and 15.2 certified for drag strip use - meets sanctioning body requirements for competition at the strip.
• Raised center cap design provides added axle clearance for low-slung Corvette rear suspensions.
• Gloss black finish with milled spoke windows for a high-contrast, race-focused appearance.
• Engineered to clear OEM Corvette C5, C6, and C7 Z06 / Grand Sport rear brake packages without modification.
• Lightweight construction reduces unsprung and rotating mass for improved 60-foot times and overall drag strip performance.

Product Description

The Weld Ventura Beadlock S904 in 17x11 is a purpose-built drag racing wheel engineered specifically for C5, C6, and C7 Corvette Z06, Grand Sport, and ZR1 owners who demand complete tire security on the strip. The true beadlock design uses a 6061-T6 aluminum scalloped ring with Heli-Coil thread inserts to mechanically clamp the tire bead to the rim barrel, eliminating any risk of tire slip or unseating during the explosive torque loads of a high-horsepower drag launch. Combined with inner and outer barrel knurling, this wheel provides the most mechanically secure tire retention available in a street-legal drag wheel package.

Built using Weld's Rotary Formed flow-formed barrel monoblock process, the wheel achieves an excellent strength-to-weight ratio by compressing the barrel material under heat and pressure during manufacturing - resulting in a denser, stronger barrel than a conventional cast wheel without the cost of a full forging. The +43mm offset and 7.75" backspacing are dialed precisely for C5 Z06, C6 Z06/Grand Sport/ZR1, and C7 Z06/Grand Sport/ZR1 rear fitment, placing a wide drag radial or ET Street tire correctly within the factory wheel well. Note that C6 and C7 Base and Z51 models are not compatible at this offset; those applications use a different size.

The wheel carries SFI 15.1 and 15.2 certification, making it eligible for use at most sanctioned drag racing events. A raised center cap is included to provide clearance over the Corvette's rear axle hub, ensuring a clean fit without contact. This wheel is sold individually, pairing naturally with a dedicated front runner or street wheel for a full drag setup. Whether the build is a street-driven Z06 running drag radials on weekends or a dedicated strip car chasing quicker quarter-mile times, the Ventura Beadlock S904 delivers the hardware confidence that high-power Corvette builds require.
