Thrust Washer - SBC - 2.950 x 1.880 x .031

The JESEL Thrust Washer for SBC (Small Block Chevy) is a precision bronze component designed to manage crankshaft endplay in high-performance engine builds. With an outer diameter of 2.950 inches, inner diameter of 1.880 inches, and a thickness of 0.031 inches, this thrust washer maintains critical clearances between the crankshaft and block in demanding racing and street performance applications.

Bronze thrust washers are engineered to provide controlled friction and wear resistance under the extreme forces generated by engine operation. The 0.031-inch thickness specification is critical—too thin and endplay tolerance becomes unpredictable; too thick and you risk altering critical crankshaft positioning. JESEL's manufacturing tolerances ensure this washer fits within the tight specifications required for SBC engines, where endplay control directly affects bearing wear patterns, oil flow distribution, and overall engine longevity. The natural bronze finish resists corrosion while maintaining the bearing surface quality needed for smooth crankshaft rotation.

This component is essential for engine builders, machine shops, and enthusiasts rebuilding or upgrading small block Chevrolet engines. Whether assembling a stock rebuild, a street performance engine, or a racing platform, correct endplay management prevents catastrophic bearing failure and maintains oil pressure integrity. The JESEL thrust washer WSH-39600 is sold individually, allowing builders to source exactly what their specific engine assembly requires without excess inventory.

Small block Chevy engines remain the most commonly rebuilt and upgraded platform in street and racing applications, making precision crankshaft components like this thrust washer fundamental to quality machine work. Pairing this washer with proper block preparation and correct assembly techniques ensures reliable performance across the full rpm range.
