Wilwood 270-13636 Forged Billet Hat Mount Hub Assembly Double Drilled 5x4.50 / 5x4.75

The Wilwood 270-13636 is a Forged Billet Hat Mount Hub Assembly engineered for precision fitment in high-performance disc brake applications. Each hub begins as a premium-grade alloy billet that is forged under intense heat and pressure to maximize structural integrity, then CNC machined to exact tolerances for a reliable fit on compatible spindle applications.

Designed specifically for use with aluminum mounting hats, this hub is double drilled to accommodate two popular wheel bolt patterns — 5 x 4.50" and 5 x 4.75" — giving installers flexibility across a wide range of wheel choices without requiring a separate hub for each pattern.

Key Features:

• Forged billet alloy construction — formed under high heat and pressure for superior strength and fatigue resistance
• CNC machined for precise spindle fitment and consistent concentricity
• Double drilled wheel lug pattern — accommodates both 5 x 4.50" and 5 x 4.75" bolt circles
• Designed for use with aluminum mounting hats
• Includes pre-installed bearing races for straightforward assembly
• Includes screw-on aluminum dust caps to protect bearings from contamination

The Wilwood 270-13636 hub assembly delivers the precision manufacturing and durable materials that performance brake builders demand, making it a reliable foundation for custom and high-performance street or track brake system builds.
