Eastern Motorcycle Parts Oil Pump Relief Valve Spring

Key Features:

• Accurate reproduction of the original equipment relief valve spring
• Designed to restore factory-style oil pressure regulation in the oil pump
• Replaces the corresponding Harley-Davidson OEM spring for each part number
• Made in the USA
