The springs are constructed from a Super Clean Chrome Silicon Vanadium Steel Alloy, ensuring durability under demanding conditions.\n\nEach kit includes ultra-light Grade 5 Titanium retainers, contributing to reduced valvetrain mass and improved high-RPM response. The dual spring design provides 95 lbs of seat pressure at a 40.4mm installed height and 261 lbs of open pressure at 12mm. Key dimensions include an outer spring OD of 30.00mm, an inner spring OD of 21.30mm, a maximum valve lift capability of 15.3mm, and a coil bind clearance of 22.7mm.\n\nThis comprehensive kit is designed for specific Honda and Acura models including the S2000 (F20C\/F22C), Civic Si (K20A3\/K20Z3), Acura RSX Type-S (K20A2), Acura RSX Base (K20A3), Acura TSX (K24A2\/K24Z3), CR-V (K24A1), Accord (K24A4\/K24A8), and Element (K24A4). It also fits standalone K20A JDM engines. Always verify your cam profile's lift against the 15.3mm maximum and the 22.7mm coil bind clearance before installation. A light cleanup of retainer seats is recommended during installation for optimal performance.","brand":"Supertech","offers":[{"title":"Default Title","offer_id":52866419589432,"sku":"SPR-H1021D-K","price":606.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687703078.webp?v=1787907541","url":"https:\/\/store.motormia.co\/products\/dual-valve-spring-kit-with-titanium-retainers-2","provider":"MOTORMIA","version":"1.0","type":"link"}
