Wilwood 270-6513UBLS Starlite 55 Wide 5 Rear Disc Brake Hub Black Less Races

The Wilwood Starlite "55" Wide 5 rear disc brake hub delivers the superior strength of permanent-mold, high-density aircraft aluminum at a weight that rivals far more expensive magnesium hub assemblies. Engineered specifically for serious racing applications, this rear hub combines proven structural integrity with an aggressive weight-reduction design that sets it apart from traditional eight-bolt magnesium alternatives.

Key Features:

• High-Density Aircraft Aluminum Construction — Permanent-mold casting provides consistent strength and durability at a fraction of the cost of magnesium assemblies
• Wide 5 Bolt Pattern — Features a five-bolt drive flange configuration optimized for racing applications
• Lightweight Redesign — Unnecessary weight eliminated from the hub body and all related components; assembled weight under 7 lbs with bearing races and studs installed
• Standard Caliper Offset — Direct-mount design with standard offset for broad caliper compatibility
• Long 5/8" Coarse Studs Included — Supplied with long-length 5/8" coarse ("C") studs for secure wheel retention
• Black E-Coat Finish — Corrosion-resistant black finish for durability in demanding race environments
• Less Races Configuration — Sold without bearing races, allowing racers to select and install their preferred race components
• Rear Hub Application — Specifically designed and configured for rear axle use

When combined with the weight savings of the five-bolt drive flange and bolt kit, the assembled Starlite "55" hub meets or beats the assembled weight of nearly every eight-bolt magnesium hub assembly on the market — delivering a competitive edge where unsprung weight matters most.
