Skunk2 Alpha Series Honda/Acura D Series Valve Spring and Titanium Retainer Kit

If you're working on the valvetrain for your 1992-2000 Honda Civic or del Sol, this Skunk2 Alpha Series Valve Spring and Titanium Retainer Kit is a solid choice. This kit is designed to keep your valves stable and prevent float, even when your engine is spinning well over 10,000 RPM. That kind of stability is crucial for performance builds where you're pushing the engine hard.

Skunk2 builds these springs using clean, chrome-silicone wire from Japan, which is known for its strength and consistency. The titanium retainers are a key part of this kit; they're significantly lighter than stock, which not only helps with valvetrain stability but also frees up a little bit of horsepower. Skunk2 uses advanced design tools like 3D CAD and FEA to optimize these retainers for strength and weight, and they're made from medical-grade titanium. Each retainer is carefully inspected to ensure it meets specifications for proper installed height and spring pressure, which is important for consistent performance.

This kit includes dual valve springs and the titanium retainers, enough for a full set of 16 valves. With a seat pressure of 62 lbs and an open pressure of 168 lbs, these springs are built to handle demanding engine speeds.
