8138-34-Z Crankcase bolt kit

This Colony crankcase bolt kit is designed for the transition years of the Big Twin, fitting 1965 to 1969 Panhead and early Shovelhead models. The kit features hex-head bolts finished in zinc plating, providing a durable and authentic look for your engine cases. During an engine overhaul, original case bolts are often found to be stretched or damaged from years of service. This kit replaces that old hardware with precision-made fasteners that ensure your crankcases are held together with the correct tension. It is a vital component for any mechanic looking to build a reliable and leak-free bottom end on a late 60s Harley.
