Spacer Gear 6 Spline

The Spacer Gear 6 Spline is a critical drivetrain component engineered for high-performance differential assemblies and racing applications. Built by Winters, a trusted name in competition-grade automotive components, this spacer serves as a precision positioning element within gear train systems. Whether you're assembling a custom drag racing setup, restoring a performance build, or upgrading an existing differential, the 6-spline design ensures proper gear alignment and load distribution across the drivetrain.

The 6-spline configuration provides secure mechanical engagement while maintaining the precise axial positioning required for optimal gear mesh. At just 0.11 lbs and measuring 2.75 x 0.65 x 2.95 inches, this compact spacer integrates seamlessly into tight differential housings without sacrificing durability or load capacity. The spline geometry distributes torque evenly across multiple contact points, reducing stress concentration on individual teeth and enhancing longevity under high-RPM conditions. Winters' manufacturing tolerances ensure consistent fit and function across multiple applications, critical for maintaining differential dynamics and reducing parasitic drag.

Mechanics and enthusiasts building performance differentials—particularly those running custom gear ratios or competition setups—depend on precision spacers to maintain proper preload and gear backlash. Installation requires careful attention to assembly sequence and torque specifications, making this component ideal for professional shops and experienced builders. The Winters Spacer Gear 6 Spline (MPN 1372) is compatible with Winters differentials and similar high-performance platforms, though verification against your specific differential casting and configuration is essential before purchase. Proper installation ensures years of reliable, efficient power delivery to the wheels.
