Skunk2's Racing Alpha valve springs/retainer kits include their high-quality dual valve springs and race-proven titanium retainers that are the result of nearly two decades of racing and engine building experience.
Each Alpha valve spring is manufactured exclusively from super-clean, chrome-silicone wire milled in Japan. By using inner and outer springs mated together through a slight interference fit and with differing frequencies, Alpha valve springs are able to prevent valve float and maintain valvetrain stability at engine speeds in excess of 10,000 rpm.
The titanium retainers are designed to significantly reduce valvetrain mass, resulting in more horsepower and improved valvetrain stability. They feature radius-cut edges for additional rocker arm clearance and reduced weight, strategically positioned lightening grooves, and reduced overall heights for better valve seal clearance and even further weight reduction. Only medical-grade titanium that is ultrasonically inspected and certified is used. They are CNC machined, inspected to ensure proper hole diameter and taper, and serialized.
For exceptional performance, reliability, and quality, choose a Skunk2 Racing Alpha valve spring/retainer kit packaged for your vehicle.
