DUAL VALVE SPRINGS 1.320″ OD 135-400LBS@1.770″ .650″ LIFT

Description

Maximize engine valve control and durability with dual valve springs engineered for high-performance applications. These springs address the critical need for maintaining consistent valve seating and preventing float at elevated camshaft lifts, ensuring optimal engine efficiency and power output.

Dual spring design offers a progressive spring rate, starting at 135 lbs and increasing up to 400 lbs at 1.770″ coil bind. This range provides superior resistance to valve float during aggressive .650″ lift camshaft operation, enhancing valve stability at high RPMs and reducing the risk of valve damage or mis-timing.

Measuring 1.320″ in outer diameter, these springs fit a wide range of engine heads while maintaining compactness for tight valvetrain assemblies. The precise dimensions—26.20 cm in length, 5.80 cm in width, and 7.40 cm in height—ensure compatibility with standard valve train components and ease of installation.

Manufactured by Comp Cams, a trusted brand in engine components, these springs weigh 1.6330 kg, balancing durability with minimal added mass to the valvetrain. The dual coil construction improves longevity under rigorous conditions by distributing stress more evenly compared to single spring designs.

These valve springs excel in applications requiring reliable performance under high lift and RPM conditions, such as racing or heavy-duty street engines. Their ability to maintain spring force consistency over time translates to improved engine responsiveness and reduced mechanical wear.

Installation of these dual valve springs enhances camshaft compatibility, preventing valve bounce and ensuring precise timing throughout the engine’s operating range. Their robust design supports efficient combustion and contributes to overall engine reliability.

Comp Cams dual valve springs deliver engineered precision and endurance, critical for maintaining peak engine performance under demanding conditions. Their specific spring pressure range and dimensional accuracy make them an essential upgrade for serious engine builders seeking consistent valve control and durability.
