The Spacer Front Brg. is a precision-engineered bearing spacer designed for Winters Sprint and Midget quick-change rear end assemblies. As a seasoned mechanic, you know that proper bearing preload and alignment are critical to rear-end durability and consistent performance on both the track and the street. This steel spacer serves as the load-bearing interface between the lower shaft and swivel coupler, maintaining exact shaft geometry while reducing bearing wear and extending drivetrain life. Quick-change rear ends demand exacting tolerances, and this component delivers that standard every time.
Constructed from cadmium-plated steel, the Spacer Front Brg. resists corrosion while maintaining dimensional stability under thermal cycling and high-load racing conditions. The cadmium finish provides superior bearing surface protection and reduces friction at the coupling interface—critical for minimizing parasitic drag losses. At just 0.06 lbs, this spacer adds negligible unsprung weight while its compact dimensions (3.3 x 0.45 x 4.5 inches) ensure it fits precisely within the Winters assembly without interference. The tight tolerances ensure that preload remains consistent across multiple assembly and disassembly cycles, which is essential for teams running multiple gear sets or performing seasonal maintenance.
This spacer is ideal for Sprint car, Midget, and other open-wheel racing platforms that rely on Winters quick-change housings for rapid gear changes and reliable performance. Whether you're a shop technician rebuilding a rear end, a team owner maintaining fleet equipment, or an engine builder sourcing OEM-spec components, this bearing spacer is essential for proper assembly integrity. Installation requires only that the lower shaft and swivel coupler be correctly positioned within the quick-change housing—standard procedure for any Winters rear-end rebuild. Order this Winters component (MPN 6680) to restore full bearing preload compliance and ensure your next race weekend runs without drivetrain surprises.
