Skunk2 Racing Pro Series XP Valve Spring Set for Honda/Acura B-Series VTEC Engines

Description

The Skunk2 Racing Pro Series XP Valve Spring Set is designed specifically for high-performance Honda and Acura B-series VTEC engines. Crafted from super-clean chrome-silicone wire milled in Japan, these dual valve springs are engineered to withstand extreme high RPM conditions and support high-lift camshafts. Each spring features a seat pressure of 93 lbs at 1.320 inches and an open pressure of 238 lbs at 0.820 inches, ensuring robust valvetrain stability during aggressive engine operation. This set includes 16 springs, making it ideal for racing or heavily modified street applications where valve float prevention and durability are critical.
Manufactured through a rigorous process that includes heat-treating, shot-peening, and a nitriding finish, the springs are designed to resist load loss and fatigue even under intense conditions. The interference-fit design of the inner and outer springs prevents valve float at engine speeds exceeding 11,000 rpm, ensuring consistent performance during extended high-RPM runs. Skunk2’s commitment to quality guarantees that each spring is eddy-current inspected, chemically polished, and treated for maximum strength and longevity. These valve springs are compatible with various Honda and Acura models from the mid-1990s to early 2000s, making them a reliable upgrade for enthusiasts seeking championship-level performance and reliability.
Whether used for turbocharged setups or high-RPM racing applications, the Skunk2 Pro Series XP Valve Spring Set offers superior resistance to load loss and stability for extreme high-performance engines. Designed for durability and precision, these springs are a top choice for professional engine builders and racers aiming to push their engines beyond standard limits while maintaining valvetrain integrity.
