723375 Fits K 1952 1953 White Plated Bolt Kit OEM 4666 4718

This Colony cylinder head bolt kit is engineered specifically for the KH and KR Sidevalve models, providing a complete set of head bolts, nuts, and washers. These are not your average fasteners; they are machined from high-strength steel and hardened to meet original Harley-Davidson specifications, ensuring they will not stretch under load. The bolts feature rolled threads, which offer significantly more strength and a better fit than standard cut threads. To ensure they look as good as they perform, all components are plated for a clean finish and long-lasting corrosion resistance. It is a top-tier hardware solution for any mechanic looking to secure the top end of a classic Harley Flathead with total confidence.
