Each kit includes Skunk2's high-quality race-proven dual valve springs that are the result of nearly two decades of racing and engine building experience. 'XP' features a higher seat pressure for turbocharged and extreme high RPM motors. This spring has a seat pressure of 93lbs @ 1.320 in. while keeping the coil bind height for higher lift camshafts. Each Pro Series XP Racing Valve Spring is manufactured exclusively from super-clean, chrome-silicone wire milled in Japan. By using inner and outer springs mated together through a slight interference fit and with differing frequencies, Pro Series XP Racing Valve Springs are able to prevent valve float and maintain valvetrain stability at engine speeds in excess of 11,000 rpm. Wound by a premier North American winder, our Pro Series XP Racing Valve Springs retains its durability and strength that results in improvement to the extreme fatigue limit of the wire and enhanced resistance to load loss. Pro Series XP Racing Valve Springs are engineered to handle the demands of extreme-lift camshafts operating at prolonged, high-rpm use at championship-level racing. Skunk2's Pro Series XP Racing Valve Spring's for the Honda's B-series VTEC engines are simply the best on the market. Pro Series XP Racing Valve Springs have been tested at speeds exceeding 11,000 rpm on our engine dyno, street, and the race track. Our superior, Japanese-milled, super-clean chrome silicone wire is 100-percent eddy-current inspected prior to coiling. Next, they are heat-treated, shot-peened, and chemically polished for strength and durability. A special nitriding process concludes Skunk2's rigorous manufacturing process. The end result is a lightweight valve spring that safely accommodates high-lift camshafts and features superior resistance to load loss, even under extreme operating conditions.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Description - Extended\u003c\/h2\u003e\n\u003cp\u003ePro Series XP Valve Spring Set; Seat Pressure 93 Lbs At 1.320 in.; Open Pressure 238 Lbs At 0.820 in.; Coil Bind 0.718 in.; Set of 16;\u003c\/p\u003e\n\n\u003ch2\u003eProduct Description - Short\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eSkunk2 Pro Series Honda\/Acura B-Series VTEC XP Valve Spring Set (Dual Springs)\u003c\/li\u003e\n  \u003cli\u003eValve Spring Kit\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eFeatures and Benefits\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003ePrevents Valve Float\/Maintain Valvetrain Stability +10000rpm\u003c\/li\u003e\n  \u003cli\u003eManufactured From Super-Clean Chrome-Silicone Wire\u003c\/li\u003e\n  \u003cli\u003eOpen Pressure 238 lbs.

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.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Description - Extended\u003c\/h2\u003e\n\u003cp\u003eAlpha Series Valve Spring And Retainer Kit; Seat Pressure 62 Lbs At 1.500 in.; Open Pressure 168 lbs.; Incl.
