Perfect Circle TW-611S Engine Crankshaft Thrust Washer Set

The Perfect Circle TW-611S is a precision-engineered crankshaft thrust washer set designed to control axial movement and provide a reliable bearing surface for engine crankshafts. This direct replacement thrust washer set is specifically designed for Mopar Gen III HEMI engines, including 5.7L, 6.1L, 6.2L, and 6.4L applications.

Key Features:

• Tri-metal construction (TM-77 material) with copper, lead, and tin alloy on a steel backing for superior wear resistance
• Stock thickness of 0.102 inches for OE-spec fitment
• Tapered ramps and contoured surfaces for optimal oil distribution
• Tear-drop grooves on flange faces allow engine oil to enter between shaft and bearing surfaces
• Manufactured to meet or exceed OE specifications
• Sold as a complete pair for proper installation

Thrust washers are critical engine components that limit crankshaft axial movement while supporting axial loads during engine operation. The TM-77 tri-metal bearing material provides exceptional load-carrying capacity and resistance to fatigue under extreme operating conditions. The independent design from the journal bearing promotes better alignment and more uniform contact with the crankshaft surface.

Perfect Circle is part of the Clevite 77 family of engine bearings, renowned for quality and precision in engine component manufacturing. This thrust washer set installs in the factory location with no modifications required.
