Exhaust Valve Spring - Mopar (68319331AA)

The Exhaust Valve Spring - Mopar (68319331AA) is a genuine OEM engine valvetrain component engineered to maintain proper exhaust valve operation by controlling valve movement and ensuring consistent seating within the cylinder head assembly. Manufactured to Mopar’s exact factory specifications, this exhaust valve spring provides reliable tension, accurate valve control, and dependable engine performance under demanding operating conditions.

Constructed from high-strength automotive-grade spring steel with heat-treated and fatigue-resistant properties, this exhaust valve spring is designed to withstand continuous compression cycles, extreme engine temperatures, and high-RPM engine operation. Its durable construction helps resist weakening, deformation, fatigue, and premature wear for long-lasting valvetrain reliability.

Functionally, the exhaust valve spring applies the necessary force to close the exhaust valve after camshaft activation, helping maintain proper valve timing, sealing, and combustion efficiency. Proper valve spring operation is essential for stable engine performance, smooth combustion cycles, and prevention of valve float at higher engine speeds. A worn or weakened valve spring may result in misfires, reduced engine performance, abnormal valvetrain noise, or potential engine damage.

As a genuine Mopar OEM component, this exhaust valve spring is manufactured to precise factory tension specifications, coil dimensions, spring rates, and fitment tolerances to ensure direct compatibility with the original cylinder head and valvetrain assembly. This guarantees reliable installation, accurate valve control, and factory-quality engine performance compared to aftermarket alternatives.

Installation is recommended during cylinder head service, valvetrain repairs, or engine rebuild procedures. Proper installation helps maintain valve timing accuracy, dependable engine operation, and long-term valvetrain durability.
