3351-4 Knucklehead rocker arm thrust washer set (4)

This rocker arm thrust washer set from Colony is sold as a set of four and is an essential component for any Knucklehead top-end rebuild. These washers are precision machined and heat treated for maximum durability, designed to withstand the stresses of the valvetrain. They fit 1936 to 1947 Knucklehead models and serve as a direct reproduction of OEM 17465-36. While this specific set replaces the thrust washers, they are often used in conjunction with packing washers like OEM 17482-36. Proper spacing of the rocker arms is critical for quiet operation and long-term reliability of the engine. These Colony washers provide the exact tolerances needed to keep your vintage overhead-valve motor running smoothly.
