Drive Flange Wide 5 8 Bolt Alum W/ Extd Loc

The Winters Drive Flange Wide 5 8 Bolt Aluminum with Extended Lock is a precision-engineered hub component designed for high-performance automotive and motorsport applications requiring reliable power transmission. Built for racers, fabricators, and performance builders who demand zero-slip hub engagement, this drive flange serves as the critical interface between drive shafts and wheel assemblies on vehicles equipped with Wide 5 bolt patterns. The extended lock design ensures axle retention under extreme acceleration, deceleration, and cornering loads typical in drag racing, road racing, and street performance environments.

Machined from aluminum and black anodized for corrosion resistance and visual clarity, this 8-bolt drive flange features a 24-spline interface with o-ring sealing to contain oil within sealed hub assemblies. The aluminum construction reduces unsprung weight compared to steel alternatives, improving suspension response and braking performance while the o-ring seal prevents oil leakage during sustained high-speed operation. At 0.86 lbs, the compact design (5.2 x 4.35 x 6.4 inches) integrates seamlessly into tight custom fabrication scenarios. The bolt-on cap design allows straightforward installation and removal for maintenance without specialized equipment, making field service accessible to experienced builders.

This drive flange is essential for builders constructing or maintaining oil-filled Wide 5 hub assemblies on race cars, pro street vehicles, and high-output performance platforms. Compatibility depends on your existing Wide 5 hub specifications and shaft design—verify spline count, bolt diameter, and oil-fill configuration before ordering. Installation requires proper torque sequencing and o-ring lubrication to ensure leak-free operation. The extended lock feature is particularly critical in vehicles exceeding 400 horsepower or regularly experiencing launch loads that stress traditional hub designs.
