9000-4 Head bolt cover kit. Acorn, chrome

Clean up the look of your Evolution engine with this Colony head bolt cover kit. These chrome-plated Acorn-style covers are designed to fit directly over the original head bolts, providing a custom finished appearance without the need for complex disassembly. Each cover mounts securely using a discreet set-screw to ensure they stay in place even under high vibration. This kit is sold as a set of four and is specifically designed to fit 1984 to early 1985 Evolution Big Twin models. It is an easy and effective way to add some extra chrome to your top end while hiding weathered factory hardware.
