Thrust Washer - BBC - 2.950 x 1.960 x .031

The Thrust Washer – BBC – 2.950 x 1.960 x .031 by JESEL is a precision-engineered component designed for high-performance big-block Chevrolet engine builds. Thrust washers are critical load-bearing components that manage axial (end-to-end) movement of the crankshaft, preventing metal-to-metal contact and maintaining proper engine geometry under extreme horsepower and rpm conditions. Whether you're assembling a competition engine, rebuilding a performance platform, or maintaining existing machinery, this JESEL thrust washer delivers the dimensional accuracy and material quality that separates reliable powerplants from those prone to catastrophic failure.

JESEL thrust washers are manufactured from premium bearing bronze and steel alloy composites, engineered to handle sustained high-load cycles without galling, wear, or dimensional drift. The 2.950-inch outer diameter and 1.960-inch inner diameter fit standard BBC main bearing housings, while the .031-inch thickness ensures precise crankshaft clearance tolerances—critical for preventing bearing knock and maintaining oil film integrity. These washers are precision-ground to exact specifications and micro-finished to ensure uniform load distribution and minimal friction losses during engine operation.

This thrust washer is essential for BBC engine builders, vintage car restorers, and performance engine shops preparing big-block builds for dyno testing, street duty, or competition service. Installation requires careful alignment during crankshaft assembly—position the washer against the crankshaft flange within the bearing housing and verify clearance before final assembly. JESEL's reputation for dimensional consistency makes this component ideal for situations where factory replacements have worn or where you need to establish tight, reproducible clearances in freshly bored or honed main bearing caps. Proper thrust washer selection prevents end-play issues, oil starvation, and expensive bearing damage downstream.
