Daytona Iron Pinion Support

The Daytona Iron Pinion Support is a heavy-duty differential carrier component engineered for Ford 9-inch axle assemblies operating in high-performance and racing applications. Cast from iron and finished in natural state, this pinion support is designed to handle the demanding loads encountered during acceleration, cornering, and sustained track use where factory components may exhibit deflection or wear.

Configured with 28-spline engagement, this support bolsters pinion bearing preload consistency and gear mesh stability—critical factors in maintaining efficient power transfer and minimizing parasitic losses. The iron construction provides superior rigidity compared to aluminum alternatives, reducing flex under torque and extending component service life in applications where structural integrity is non-negotiable. The race-installed configuration indicates pre-assembly and validation, streamlining installation into prepared differentials.

Built for drag racing, road course competition, and high-powered street vehicles, the Daytona pinion support serves builders and technicians who prioritize precision and repeatability in Ford 9-inch differential setups. Whether upgrading an existing assembly or constructing a new differential from components, this support addresses the need for enhanced structural support where factory designs reach their limits. Weighing 6.95 pounds, it integrates into standard Ford 9-inch housings without modification.
