The WEHRS MACHINE Pinion Mount Spacer with Bolt (Model WM503) is a precision aluminum component engineered for drivetrain assembly in high-performance and competition applications. This black anodized spacer serves as a critical positioning element between the pinion gear and mounting surface, ensuring proper gear mesh alignment and load distribution in rear axle assemblies. The included bolt completes the fastening system, eliminating the need for separate hardware sourcing.
Manufactured from aluminum and finished with black anodize coating, this spacer delivers corrosion resistance and repeatable dimensional accuracy. The anodized finish provides a durable protective layer while maintaining the lightweight profile critical in performance applications where unsprung weight directly impacts suspension response and handling. At 0.95 pounds and dimensioned at 4 x 3.25 x 4.55 inches, the spacer integrates seamlessly into standard axle housings without requiring frame modifications or secondary machining.
This component is specified for competition drag racing, off-road racing, and performance street builds where precise pinion angle and gear mesh geometry directly affect power transmission efficiency and component longevity. WEHRS MACHINE components are engineered to exacting standards and are frequently used by professional racing teams and performance shops requiring OEM-level fitment and reliability. The WM503 spacer with bolt is an OEM-equivalent replacement or upgrade component suitable for builders prioritizing correct geometry over generic alternatives.
