14-45 Cylinder Head Bolt Kits for Sidevalves

Restoring a classic 45-inch Sidevalve requires attention to detail, and this Colony cylinder head bolt kit delivers exactly that. This high-quality set includes the head bolts, nuts, and washers needed for a complete installation. Each component is accurately machined from high-strength steel and hardened to original Harley-Davidson specifications to prevent stretching over time. The bolts feature rolled threads, which provide superior strength and a much better fit than standard cut threads. To ensure your Flathead looks as good as it runs, all pieces are plated for excellent corrosion resistance and a clean, finished appearance. This kit is a direct replacement for OEM 14-45, offering the reliability and period-correct look required for vintage 45-inch models.
