Variation line-up SS-CAM (STEP1) HKS SS-Cam are designed to fit unmodified cylinder heads with stock Valve Springs to be a simple bolt on cam kit that can give added performance without changing any other parts or the valve timing.By changing cams, cam duration and lift is a
Fitment and specifications can vary by HKS part number, model year, trim, transmission, drivetrain, and market. Confirm the SKU and application before ordering, particularly on modified vehicles.
