Flywheel Thrust Washers

10 products

Flywheel Thrust Washers for Harley-Davidson are critical engine components that control crankshaft end play and prevent metal-to-metal contact between the flywheels and crankcase. These precision-machined washers cover applications from early Flathead and Knucklehead engines through to Evolution and Shovelhead Big Twins, as well as Sportster XL powerplants. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, supplies flywheel thrust washers from MCS, a trusted source for OEM-equivalent engine internals. Correct flywheel end play is essential for engine longevity, and worn thrust washers should be replaced during any bottom-end rebuild to maintain proper clearances and prevent costly damage.
