HKS 22001-AN002 High Performance Valve Spring Set - for High-Lift Camshafts

The HKS 22001-AN002 Valve Spring Set is engineered specifically to complement HKS high-performance camshafts, delivering the increased spring rates required to maintain precise valve control at elevated RPM. As aggressive cam profiles demand greater valve lift and faster actuation, stock valve springs become a limiting factor — these HKS springs are purpose-built to meet those demands.

Key Features:

• Matched to HKS Camshafts: Spring rates are precisely calibrated to the lift and duration characteristics of HKS cam profiles
• Shot-Peened Construction: A stringent shot-peening process is applied to each spring for enhanced surface durability and fatigue resistance
• Heat Treated: Specialized heat treatment ensures consistent spring rates and long-term reliability under sustained high-RPM use
• Valve Float Prevention: Stiffer spring rates significantly reduce the risk of valve float at high engine speeds
• Coil-Bind Resistance: Designed to minimize coil-bind risk when used with high-lift cam profiles
• Direct Upgrade: A necessary complement when upgrading from stock camshafts to high-lift HKS performance cams

Applications with high-revving engines benefit greatly from the HKS 22001-AN002 valve spring set. By replacing inadequate OEM springs with these performance-grade units, valve train stability is maintained throughout the RPM range, helping protect engine components and maximize the power potential of your HKS camshaft upgrade.
