Description
Factory headbolts are engineered to specific torque specifications—once they’ve been removed and reinstalled, they lose clamping force and reliability. COLONY 12-point replacement headbolts restore proper cylinder head clamping on Big Twin and Twin Cam XL engines, preventing gasket failure, coolant leaks, and cylinder head separation under load. Precision-manufactured in the U.S.A., these bolts meet OEM performance standards and are essential for any engine rebuild or head service.
