Skunk2 Alpha Series Honda D-Series Valve Spring and Titanium Retainer Kit

Skunk2 is proud to introduce its Alpha Valve Spring and Titanium Retainer Kit for Honda's D-series VTEC engines. Each kit includes Skunk2's high-quality valve springs and race-proven titanium retainers that are the result of nearly two decades of racing and engine building experience. Manufactured exclusively from super-clean, chrome-silicone wire milled in Japan, Skunk2's Alpha Valve Springs for Honda's D-series VTEC engines are a product of the company's years of racing and engine building experiences. Alpha Valve Springs are able to prevent valve float and maintain valvetrain stability at engine speeds in excess of 10,000 rpm. Skunk2's industry-leading Alpha Titanium Retainers 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.

Upgrade your Honda D-series VTEC engine with the Skunk2 Alpha Series Valve Spring and Titanium Retainer Kit, designed for high-performance applications and proven in racing environments. This comprehensive kit includes dual valve springs and lightweight titanium retainers, engineered to deliver exceptional valvetrain stability and maximum horsepower at engine speeds exceeding 10,000 rpm. Crafted from premium chrome-silicone wire sourced exclusively from Japan, the valve springs provide consistent seat pressure of 62 pounds and open pressure of 168 pounds, ensuring reliable valve control under intense conditions. The springs are manufactured to exacting standards, with each component individually inspected to guarantee proper fitment and optimal performance. The titanium retainers are designed to reduce valvetrain mass significantly, allowing for quicker valve response and improved engine revving capabilities. Featuring radius-cut edges for increased rocker arm clearance and strategically placed lightening grooves, these retainers benefit from advanced 3D CAD and FEA analysis to optimize strength-to-weight ratio. The use of medical-grade titanium, certified and ultrasonically inspected, ensures durability and safety under race conditions. After CNC machining, each retainer undergoes rigorous quality control to maintain precise hole diameters and tapers, ensuring proper valve spring heights and pressures. This kit is a direct fit for Honda Civics and Del Sols from 1993 to 1997, making it an ideal upgrade for enthusiasts seeking reliable, high-performance valvetrain components. Whether for daily driving or competitive racing, the Skunk2 Alpha Series kit delivers enhanced valvetrain stability, increased horsepower potential, and reduced component weight, contributing to overall engine efficiency and durability.
