About This Product
Colony manufactures these lifter base and tappet block screws in the USA to provide a reliable fastening solution for securing lifter blocks to the Harley-Davidson crankcase. This complete set replaces the original hardware, ensuring a precise fit and period-correct appearance for engine rebuilds or routine maintenance.

Choosing Colony ensures that your engine hardware meets exacting standards for thread accuracy and material strength, which is essential for critical engine assembly tasks. Sold as a set.
