Skunk2 Lost Motion Assemblies will fit any B-Series DOHC VTEC engine (Type-R\/GSR B16A, B17A, B18C). The Skunk2 Lost Motion Assembly is an advance spring device that is designed to put pre-load on the center portion of the VTEC rocker when it is in the unlocked position (when VTEC mode is disabled). During extended operating conditions, the contaminants in the oil will more than likely cause the piston to seize resulting in the VTEC rocker rattling when VTEC is not engaging or when the vehicle is in idle. Each Skunk2 Lost Motion Assembly is manufactured exclusively from chrome silicone steel using the latest 3D CAD (Computer Aided Design) modeling and FEA (Finite Element Analysis) to ensure maximum optimization. Each chrome silicone steel spring features a hardened tip for added durability. Skunk2 engineers then tested and proved their design on the engine dyno as well as the race track. The Skunk2 Lost Motion Assembly Kit replaces the factory piston-style LMA design with an improved design commonly found in newer generation Honda engines. Replacing LMAs are recommended when installing aftermarket camshafts and required when installing Skunk2 Pro Series and other high-lift camshafts. Each Lost Motion Assembly Kit includes a set of 8 assemblies for an entire Honda DOHC VTEC B-Series 4-cylinder engine (Type-R\/GSR, B16A, B17A, B18C) and are compatible with all camshafts. When using camshafts with +12.5mm lift, LMAs are an absolute must, and Skunk2 Lost Motion Assembly springs are 3 percent stiffer than ITR springs.","brand":"Skunk2 Racing","offers":[{"title":"Default Title","offer_id":44906209968362,"sku":"SKK312-05-0200","price":112.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0477\/0427\/7142\/files\/c31a5defc254b0e73b91e98f80cea68e.jpg?v=1772904588"},{"product_id":"skunk2-honda-l15b7-ultra-valve-springs-and-spring-base-kit","title":"Skunk2 Honda L15B7 Ultra Valve Springs and Spring Base Kit","description":"Skunk2 Honda L15B7 Ultra Valve Springs and Spring Base Kit","brand":"Skunk2 Racing","offers":[{"title":"Default Title","offer_id":44906210033898,"sku":"SKK313-05-9400","price":359.4,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0477\/0427\/7142\/files\/d8e12f429daca4cd93d79f492946e64a.jpg?v=1772904598"},{"product_id":"skunk2-alpha-series-honda-acura-d-series-valve-spring-and-titanium-retainer-kit","title":"Skunk2 Alpha Series Honda\/Acura D Series Valve Spring and Titanium Retainer Kit","description":"Skunk2 is proud to introduce its Alpha Valve Spring and Titanium Retainer Kit for Honda's D-series VTEC engines.

However, 'grassroots' motorsports remain at the core of Ford's DNA. Grassroots performance began with Ford and has become a part of American culture. The  Model A is the most modified car in history, and enthusiasts the world over continue to embrace Ford, Mercury, and Lincoln cars and trucks from the 1930s right on through to today. Road racers, drag racers. circle track competitors and street rodders have channeled, stepped-on, hopped-up, chopped down and modified their favorite cars to excel on the street, at the track, and in car shows. The Ford Mustang immediately became part of this culture when it was introduced in 1964-and remains a staple of grassroots performance to this day. In 2014, Mustang marks 50 years of winning, and has driven its way into racing history. Moreover, the car's appeal is universal; a recent European study identified Mustang as the most desirable classic car in Europe. Motorsports continue to evolve, with advances in technology and greater demand for smaller powertrains, as well as growing appetite for new formats like Rally Cross and Drifting. How it develops in the next 50 years remains to be seen, but we intend to be there to celebrate it, thanks to passionate enthusiasts like you, who have driven the success of Ford, Ford Racing and Mustang since the beginning.","brand":"Ford Racing","offers":[{"title":"Default Title","offer_id":45528355832042,"sku":"FRPM-6513-M50BR","price":73.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0477\/0427\/7142\/files\/c53d28b51b52a8542e6307597f42d883L.jpg?v=1774747633"},{"product_id":"blox-racing-dual-valve-springs-for-k20a2-3-z1-3-2-0l-dohc-i-vtec-k24a-3-2-4l-dohc-i-vtec","title":"BLOX Racing Dual Valve Springs for K20A2-3 Z1-3 (2.0L DOHC i-VTEC) \/ K24A-3 (2.4L DOHC i-VTEC)","description":"BLOX Racing Dual Valve Springs for K20A2-3 Z1-3 (2.0L DOHC i-VTEC) \/ K24A-3 (2.4L DOHC i-VTEC)","brand":"BLOX Racing","offers":[{"title":"Default Title","offer_id":45674451534058,"sku":"BLOBXPT-10301","price":208.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0477\/0427\/7142\/files\/ad46d33c-7b8d-42eb-9537-2b6d1d2cc070-800.jpg?v=1774158812"},{"product_id":"blox-racing-dual-valve-springs-for-dohc-vtec","title":"BLOX Racing Dual Valve Springs for DOHC VTEC","description":"BLOX Racing Dual Valve Springs for DOHC VTEC","brand":"BLOX Racing","offers":[{"title":"Default Title","offer_id":45685481767146,"sku":"BLOBXPT-10300","price":208.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0477\/0427\/7142\/files\/7f3a5b4e-9a98-45dd-a77a-5ba1199b51e9-800.jpg?v=1774171128"},{"product_id":"blox-racing-ti-retainers-for-b16a-b18c1-5-1-6l-1-8l-dohc-vtec-h22a-2-2l-dohc-vtec","title":"BLOX Racing Ti Retainers for B16A - B18C1-5 (1.6L - 1.8L DOHC VTEC) \/ H22A 2.2L DOHC VTEC","description":"BLOX Racing Ti Retainers for B16A - B18C1-5 (1.6L - 1.8L DOHC VTEC) \/ H22A 2.2L DOHC VTEC","brand":"BLOX Racing","offers":[{"title":"Default Title","offer_id":45688697684202,"sku":"BLOBXPT-10400","price":204.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0477\/0427\/7142\/files\/4db74ec5-8b69-4d21-a463-2b48d1dbb773-800.jpg?v=1774173148"},{"product_id":"brian-crower-honda-acura-b18c-b16a-b17a-dual-spring-titanium-retainer-kit","title":"Brian Crower Honda Acura B18C\/B16A\/B17A Dual Spring \u0026 Titanium Retainer Kit","description":"Brian Crower Honda Acura B18C\/B16A\/B17A Dual Spring \u0026amp; Titanium Retainer Kit","brand":"Brian Crower","offers":[{"title":"Default Title","offer_id":45724977430762,"sku":"BRCBC0010","price":430.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0477\/0427\/7142\/files\/group-40b2a953-62cb-4226-9681-8afbf47cb06d-800.jpg?v=1777039916"},{"product_id":"brian-crower-honda-acura-b18c-b16a-b17a-dual-spring-steel-alloy-retainer-kit","title":"Brian Crower Honda Acura B18C\/B16A\/B17A Dual Spring \/ Steel Alloy Retainer Kit","description":"Brian Crower Honda Acura B18C\/B16A\/B17A Dual Spring \/ Steel Alloy Retainer Kit","brand":"Brian Crower","offers":[{"title":"Default Title","offer_id":45724977496298,"sku":"BRCBC0010S","price":339.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0477\/0427\/7142\/files\/group-40b2a953-62cb-4226-9681-8afbf47cb06d-800_74ab5cc7-f76d-4cf1-8a52-e5c007de5b94.jpg?v=1777039928"},{"product_id":"brian-crower-honda-acura-b18a-b18b-b20b-dual-spring-titanium-retainer-kit","title":"Brian Crower Honda\/Acura B18A\/B18B\/B20B Dual Spring \u0026 Titanium Retainer Kit","description":"Brian Crower Honda\/Acura B18A\/B18B\/B20B Dual Spring \u0026amp; Titanium Retainer Kit","brand":"Brian Crower","offers":[{"title":"Default Title","offer_id":45724977692906,"sku":"BRCBC0020","price":424.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0477\/0427\/7142\/files\/group-40b2a953-62cb-4226-9681-8afbf47cb06d-800_95178582-3659-48d8-b965-cfd24d17aed8.jpg?v=1774206193"},{"product_id":"brian-crower-honda-acura-b18a-b18b-b20b-dual-spring-steel-retainer-kit","title":"Brian Crower Honda\/Acura B18A\/B18B\/B20B Dual Spring \u0026 Steel Retainer Kit","description":"Brian Crower Honda\/Acura B18A\/B18B\/B20B Dual Spring \u0026amp; Steel Retainer Kit","brand":"Brian Crower","offers":[{"title":"Default Title","offer_id":45724977758442,"sku":"BRCBC0020S","price":334.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0477\/0427\/7142\/files\/group-40b2a953-62cb-4226-9681-8afbf47cb06d-800_ea5c5602-784d-494e-b18e-b4410a7f03e2.jpg?v=1777039931"}],"url":"https:\/\/www.k2-industries.com\/en-pl\/collections\/valve-springs-retainers.oembed","provider":"K2 Industries","version":"1.0","type":"link"}
