1.083 Valve Springs - Ovate Beehive (16)

The PAC RACING SPRINGS 1.083 Valve Springs - Ovate Beehive (16) are designed for high-performance automotive engines that demand exceptional valvetrain stability at high RPMs. These springs are part of the RPM Series, bridging the gap between street performance and competitive racing by effectively managing harmonic vibrations compared to standard cylindrical springs. They are essential for enthusiasts looking to upgrade their valvetrain for consistent valve timing and to prevent float during aggressive driving.

Featuring a specialized ovate beehive design, these springs utilize a variable diameter to reduce moving mass at the retainer end, broadening the frequency range to dampen resonance. The springs are engineered with a spring rate of 291 lb/in, providing the necessary tension to control high-lift camshaft profiles. The use of ovate wire enhances stress distribution across the spring coil, improving fatigue life under heavy loads.

Ideal for V8 engine builds or high-output cylinder heads that accommodate a 1.083-inch outer diameter, these springs are a preferred choice among professional engine builders. They are particularly beneficial for applications that require a reliable and lightweight valvetrain solution. With a set of 16 springs, they are perfect for those looking to enhance their engine's performance.
