Show original supplier description
This kit is ideal for builds targeting aggressive camshaft profiles with lift up to 15.3mm, suitable for both street and track use. The springs are constructed from a Super Clean Chrome Silicon Vanadium Steel Alloy, ensuring durability under demanding conditions. Each 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. This 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.
