COMP CAMS K31-493-9 COMP Cams K31-493-9 Xtreme Energy Small Block Ford Hydraulic Roller Camshaft Kit

The COMP Cams K31-493-9 Xtreme Energy K-Kit is a complete valvetrain package for Small Block Ford applications requiring responsive hydraulic roller performance. This kit combines a matched camshaft, hydraulic roller lifters, valve springs, and timing set to simplify installation and provide compatible components throughout the valve train. It is engineered for performance builds that need strong throttle response, broad power characteristics, and dependable operation across a practical street and performance driving range.
The Xtreme Energy hydraulic roller camshaft delivers 0.514-inch lift on the intake and 0.509-inch lift on the exhaust, with 270/278 degrees of duration and a 110-degree lobe separation angle. Its operating range of approximately 1,800 to 5,800 RPM supports usable low- and mid-range power while continuing to provide performance at higher engine speeds. The hydraulic roller design helps reduce friction compared with traditional flat-tappet configurations and is well suited to compatible Small Block Ford engines.
As a complete K-Kit, the COMP Cams K31-493-9 helps match the camshaft with the supporting valvetrain components needed for a cohesive installation. The included lifters, springs, and timing set are selected to complement the camshaft specifications, helping reduce component-matching concerns during an engine build or upgrade. Verify engine compatibility, cylinder head specifications, piston-to-valve clearance, spring requirements, and installation settings before assembly. This kit is intended for enthusiasts and builders seeking a coordinated camshaft and valvetrain solution from COMP Cams.
