Accurate valve-to-cam contact is critical for reliable high-RPM operation, and stock springs are often unable to keep pace with more aggressive cam profiles.\u003c\/p\u003e\u003cp\u003eManufactured from high-quality materials with advanced heat treatment and shot-peening, these springs are engineered to be durable and low-inertia, reducing the risk of valve float or coil-bind at high engine speeds. A common pairing for RB26 builds running upgraded HKS camshafts (such as the S2 or S3 profiles covered elsewhere in HKS's RB26 lineup), this Step 2 spring set helps unlock the full potential of a built engine while improving reliability under sustained high-RPM use.\u003c\/p\u003e\u003cmeta name=\"description\" content=\"Upgrade your RB26DETT with HKS Step 2 valve springs for high-lift camshafts.
