1.270 Valve Springs - Ovate Beehive (16)

The PAC Racing Springs 1.270 Valve Springs – Ovate Beehive set delivers precision-engineered valve control for high-performance engine builds requiring consistent lift and reliable valve seat control. This 16-piece set of ovate beehive springs is designed for racing and performance applications where spring rate stability and durability under extreme valve velocity are critical to engine reliability and power output.

Each spring in this set features a 400 lb/in spring rate and a 1.544-inch coil bind specification, engineered to manage valve acceleration and deceleration while preventing coil bind contact at maximum lift. The 1.270-inch outer diameter (OD) and 0.825-inch inner diameter (ID) dimensions are sized for compatibility with standard valve spring seats and retainers in performance engine platforms. The ovate beehive design reduces harmonics and spring surge compared to traditional cylindrical geometries, improving consistency across engine RPM ranges and extending spring fatigue life under high-lift, high-RPM operation.

PAC Racing Springs are standard equipment in professional engine building for street performance, road racing, and drag racing applications where valve control precision is non-negotiable. Builders specify these springs when valvetrain stability, repeatability, and durability matter more than cost. The 16-piece configuration supports dual-spring setups across eight cylinders or provides replacement inventory for long-term engine maintenance in competition vehicles.

This product is not a universal application—verify spring compatibility with your specific engine platform, intake valve diameter, and retainer design before installation. Proper installation requires torquing to manufacturer specifications and checking installed height to ensure correct preload on the valve stem.
