510060 4-speed transmission adjuster kit. Chrome

This chrome-plated steel 4-speed transmission adjuster kit is an essential piece of kit for anyone running an open belt drive or a traditional tin primary on their vintage Big Twin. Designed to mount directly to the rear side of the transmission mount plate, it provides the precise adjustment needed to dial in your belt tension and ensure perfect tracking. It is also ideal for setting chain tension on OEM-style tin primaries. This single adjustable kit fits 1936 to 1985 4-speed Big Twin models and custom builds using a 4-speed box, though it is important to note that it will not work with 1965 to 1986 style aluminum primaries. Replacing OEM part 510060, this kit offers a clean, durable solution for maintaining your driveline alignment.
