Description
The Sonnax 28406B High Clutch Drum Thrust Washer is a precision-engineered, bi-metal component designed specifically for GM Powerglide transmissions. With a thickness of 0.061 inches and inner and outer diameters measuring approximately 2.010″ and 2.690″ respectively, this washer provides a critical thrust surface between the high clutch drum and the pump assembly.
Crafted from durable bimetal material, it offers superior wear resistance and thermal stability under high-load conditions, ensuring smooth clutch operation and consistent engagement. Built to Sonnax’s rigorous standards, the 28406B replaces OE components with enhanced strength and reliability, delivering lasting performance in both routine rebuilds and heavy-duty Powerglide applications. Whether used in high-mileage or performance-focused builds, this thrust washer plays an essential role in maintaining clutch alignment, reducing endplay, and preventing drum-to-pump contact that could lead to premature failure.
