Richmond Gear Differential Pinion Shaft

Richmond Gear Differential Pinion Shafts are precision-engineered drivetrain components built to meet the rigorous demands of differential rebuilds, high-performance street builds, off-road applications, and competition racing. As a critical internal component of the differential assembly, each pinion shaft is manufactured to exacting tolerances to ensure proper gear mesh alignment, efficient power transfer, and long-term reliability under sustained load and high-torque conditions.

Key Features:

• Precision Machined Construction: Manufactured from high-quality steel with tight dimensional tolerances for consistent fit and dependable function within the differential assembly
• Heat-Treated for Durability: An advanced heat treatment process increases surface hardness and wear resistance, extending service life under high-stress and high-torque operating conditions
• OE-Spec Engineering: Designed to meet or exceed original equipment specifications, ensuring correct fit and function during differential rebuilds or performance upgrades
• Broad Application Coverage: Available across multiple configurations to accommodate a wide variety of axle and differential assemblies for street, off-road, and competition use
• Richmond Gear System Compatibility: Engineered to work seamlessly alongside other Richmond Gear differential components, including ring and pinion gear sets, cross pins, and rebuild kits
• Notched Designs Available: Select variants feature notched profiles specifically designed to clear high-numeric gear ratios, ensuring compatibility with performance-oriented ring and pinion sets
