The Skunk2 Lost Motion Assembly Kit replaces the factory piston-style LMA design with an improved design commonly found in newer generation Honda engines and incorporate a hardened tip for added durability.\nSkunk2 recommends replacing the LMA's when installing aftermarket camshafts as a preventive maintenance measure but requires replacement when installing Skunk2 Pro and Ultra Series camshafts or any camshafts with a lift greater than 12.5mm.\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage Includes:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\n\u003cli\u003eSK Tuner Valve Springs\u003c\/li\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eCompatible With:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\n\u003cli\u003e1990-2001 Acura Integra 1.8L\n\u003c\/li\u003e\u003cli\u003e1999-2000 Honda Civic 1.6L\n\u003c\/li\u003e\u003cli\u003e1994-2001 Acura Integra 1.8L\n\u003c\/li\u003e\u003cli\u003e1996-1997 Honda Civic del Sol 1.6L\n\u003c\/li\u003e\u003cli\u003e1994-1995 Honda Civic del Sol 1.6L\u003c\/li\u003e","brand":"Skunk2 Racing","offers":[{"title":"Default Title","offer_id":51814462554475,"sku":"SKK-312-05-0200","price":111.26,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1961\/1987\/files\/SKK-312-05-0200-1.jpg?v=1744776164"},{"product_id":"skk-311-05-1345","title":"Valve Spring Set \u003cbr\u003e Honda D-Series VTEC","description":"\u003cb\u003eDescription:\u003c\/b\u003e\u003cbr\u003e\n\u003cbr\u003eManufactured exclusively from super-clean, chrome-silicone wire milled in Japan, Skunk2's Alpha Valve Springs for Honda's H22\/ F20B VTEC engines are a product of the company's years of racing and engine building experiences.

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.\nSkunk2'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.\nFinally, each retainer is serialized for your protection, including valuable information, like material batch specifics as well as production and inspection dates.

By using inner and outer springs mated together through a slight interference fit and with differing frequencies, Alpha Valve Springs are able to prevent valve float and maintain valvetrain stability at engine speeds in excess of 10,000 rpm.\nAlpha 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.\nAlpha 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.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eSpecifics and Features:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\n\u003cli\u003eSpecifications:\n\u003c\/li\u003e\u003cli\u003eSeat Pressure: 50 lbs at 1.400\n\u003c\/li\u003e\u003cli\u003eOpen Pressure: 205 lbs at 0.900\n\u003c\/li\u003e\u003cli\u003eCoil Bind: 0.880\u003c\/li\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage Includes:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\n\u003cli\u003eSK Alpha Spring\/Retainer Kit\u003c\/li\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eCompatible With:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\n\u003cli\u003e1997-2001 Honda Prelude 2.2L\n\u003c\/li\u003e\u003cli\u003e1992-1996 Honda Prelude 2.3L\n\u003c\/li\u003e\u003cli\u003e1992-1996 Honda Prelude 2.2L\u003c\/li\u003e","brand":"Skunk2 Racing","offers":[{"title":"Default Title","offer_id":51814474940779,"sku":"SKK-344-05-1360","price":410.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1961\/1987\/files\/SKK-344-05-1360-1.jpg?v=1744775844"},{"product_id":"skk-311-05-7350","title":"Valve Spring Set (Dual Springs) \u003cbr\u003e Honda B-Series VTEC","description":"\u003cb\u003eDescription:\u003c\/b\u003e\u003cbr\u003e\n\u003cbr\u003eSkunk2 is proud to introduce its Pro Series XP (Extra Pressure) Racing Valve Spring Kits for the Honda B16\/ B17\/ B18 and H22\/ F20B VTEC engines.

Chromium Nitride coating is a remarkable solution as it improves the friction coefficient between the valve's stem and valve guide; a necessity for engine components that demand resistance to high heat level environments.\nOther valves may appear similar, but Only Ultra Series Valves feature specially designed valve head profiles to optimize airflow. Skunk2 designs, develops, and tests its entire valvetrain lineup in-house to ensure superior quality and maximum performance gains. Skunk2 valvetrain components provide exceptional performance, reliability, and quality and are standard-issue on each Skunk2 vehicle that we build and support.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eSpecifics and Features:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\n\u003cli\u003eAdd Skunk2 Pro Series Valve Springs and Titanium Retainers for ultimate valvetrain stability.\n\u003c\/li\u003e\u003cli\u003eOverall Valve Length (Intake\/Exhaust): 109mm\/ 108.6mm\n\u003c\/li\u003e\u003cli\u003eHead Diameter (Intake\/Exhaust): 35.00mm\/ 30.00mm\n\u003c\/li\u003e\u003cli\u003eStem Thickness (Intake\/Exhaust): 5.48mm\/ 5.45mm\u003c\/li\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage Includes:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\n\u003cli\u003eSK Ultra Valves\u003c\/li\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eCompatible With:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\n\u003cli\u003e2003-2011 Honda Element 2.4L\n\u003c\/li\u003e\u003cli\u003e2004-2007 Honda Accord 2.4L\n\u003c\/li\u003e\u003cli\u003e2004-2008 Acura TSX 2.4L\n\u003c\/li\u003e\u003cli\u003e2002-2009 Honda CR-V 2.4L\n\u003c\/li\u003e\u003cli\u003e2002-2011 Honda Civic 2.0L \n\u003c\/li\u003e\u003cli\u003e2002-2006 Acura RSX 2.0L\u003c\/li\u003e","brand":"Skunk2 Racing","offers":[{"title":"Default Title","offer_id":51814476579179,"sku":"SKK-310-05-9535","price":427.55,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1961\/1987\/files\/SKK-310-05-9535-1.jpg?v=1744775787"},{"product_id":"skk-348-05-0400","title":"24PCS OEM Style Rocker Set \u003cbr\u003e Honda H-Series VTEC","description":"\u003cb\u003eDescription:\u003c\/b\u003e\u003cbr\u003e\n\u003cbr\u003eIt has been 34 years since Honda introduced the venerable H-Series VTEC engine family. Though these engines were designed to be nearly bullet proof, it is common for the rocker arm radius pad (wear surface) to exhibit wear over time. Worn rockers negatively impact camshaft performance and durability. Unfortunately, due to the high cost of Honda Genuine replacement parts purchased from the dealer and being discontinued, most enthusiasts omit replacing the rockers when they should.\nThe Skunk2 VTEC rocker set provides an affordable replacement for OEM Honda rockers.
