Skunk2 Racing Alpha Series Titanium Valve Retainer Set for Honda D Series Engines

Skunk2's industry-leading Alpha Titanium Retainers for the Honda D Series engines are designed to significantly reduce valvetrain mass, resulting in more horsepower and improved valvetrain stability. Similar to Skunk2's already popular Pro Series Titanium Retainers, Alpha Titanium Retainers 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. Alpha Titanium 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. Finally, each retainer is serialized for your protection, including valuable information, like material batch specifics as well as production and inspection dates.

Enhance your Honda D Series engine performance with the Skunk2 Racing Alpha Series Titanium Valve Retainer Set. Designed to significantly reduce valvetrain mass, these retainers help increase horsepower and improve valvetrain stability, making them an ideal choice for racing and high-performance applications. Crafted from medical-grade titanium using advanced 3D CAD and FEA techniques, each retainer is optimized for strength and minimal weight. The radius-cut edges provide additional clearance for rocker arms and contribute to weight reduction, while strategically placed lightening grooves further decrease overall mass. These features ensure improved valve operation and reduced stress on valvetrain components. Each retainer undergoes rigorous CNC machining, ultrasonic inspection, and individual quality checks to guarantee precise hole diameters and taper angles, ensuring proper fitment and valve spring pressure. The serialized design includes valuable information about material batch, production, and inspection dates for added security. Suitable for Honda Civics from 1988 to 2000 with D Series engines, these retainers are engineered for durability and high performance.
