Overview

Skunk2 Racing Pro Series Titanium Valve Spring Retainers

Skunk2's industry-leading Pro Series titanium valve spring retainers are designed to significantly reduce valvetrain mass, resulting in more horsepower and improved valvetrain stability. Unlike other retainers, the Pro Series features 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. The retainers are manufactured using the latest 3D CAD (Computer Aided Design) and FEA (Finite Element Analysis) to ensure that each is optimized for strength, as well as for reduced weight. Skunk2 engineers then test and prove their designs on the engine dyno, as well as the race track. Once approved for manufacturing, only medical-grade titanium that's been ultrasonically inspected and certified is used. Following CNC machining, each retainer is then individually inspected to ensure proper hole diameter, taper, and that each are free from machining defects to ensure proper installed valve spring heights and pressures. Each retainer is serialized for your protection, including valuable information, like material batch specifics, as well as production and inspection dates. Order the retainers designed for your application.
