About This Product
This S&S right main bearing is color-coded blue to indicate its specific tolerance grade for precise engine assembly. It is designed for use in Big Twin crankcases, providing the necessary support for the pinion side of the crankshaft. S&S produces these bearings to strict dimensional standards, allowing engine builders to achieve the exact clearances required for optimal oil film thickness and rotational smoothness. Using graded bearings is a standard practice in professional motor rebuilding to ensure longevity and quiet operation. This bearing is sold individually.
Manufacturer part number: 31-4018.
