Spacer Helical Gears 6-Spline

The Spacer Helical Gears 6-Spline (MPN SR3416) is a precision-engineered helical gear spacer designed for quick-change rear end assemblies and drivetrain applications where axle geometry alignment is critical. This component serves as a structural spacer within Winters-style quick-change differentials, maintaining proper spacing and engagement between gear sets. Helical gear spacers are essential for users who require repeatable, accurate gear mesh and want to avoid costly misalignment issues during assembly or maintenance cycles.

Manufactured from hardened steel in a natural finish, this spacer features a 1.175-inch inside diameter and a 1.750-inch outside diameter, with a 0.362-inch thickness that ensures consistent load distribution across the differential housing. The 6-spline design provides positive indexing and prevents rotation or slippage during operation, critical for maintaining torque transmission integrity under high-stress racing or off-road conditions. The helical tooth geometry itself promotes smoother engagement and reduced noise compared to spur alternatives, while the spacer's compact profile (weighing just 0.14 lbs) minimizes parasitic weight without sacrificing structural rigidity.

This spacer is ideal for drag racers, off-road competitors, and performance enthusiasts running Winters Quick Change rear ends who demand precision fit and long-term reliability. Installation requires removal of the differential cover and alignment with corresponding splines in the carrier or side gear assembly; users should verify spline count and diameter compatibility before ordering. Proper installation with torque specifications from your differential manufacturer ensures maximum service life and eliminates potential warranty issues related to improper spacing or gear mesh.
