COMP Cams® is the only aftermarket valve train company in America that provides a Pro Plasma™ Nitriding Service in-house. Nitriding is a process by which nitrogen is introduced into iron or steel, causing a material's surface hardness to be increased for improved initial and long-term wear characteristics. It is recognized by metallurgists worldwide as the best way to increase the hardness and lubricity of flat tappet cams to enhance break-in and durability. Nitriding is available for any COMP Cams® flat tappet camshaft, but many popular flat tappet camshafts have already undergone the Pro Plasma™ Nitriding treatment and are on the shelf, ready to be shipped. Don't get blinded by shiny surface finishing or heat-treating - nitriding has been race-proven around the world and documented to deliver superior results.

A Unique Cam for Marine Applications

If you're heading to the great outdoors, Comp Cams offers camshafts designed specifically for marine applications where low idle speeds are necessary and where restrictive exhausts require special cams that work well against wet exhaust system back pressure. These unique camshafts generate an extremely wide powerband, offering the low-end torque needed to jerk skiers up quickly and the high-end power needed for maximum performance. Also, Comp's larger camshafts are engineered for engines with less restrictive exhausts and drives that will tolerate higher idle speeds. An excellent choice for jet boats or power boats.

Features:
  • Extremely wide powerband helps get boat on plane while making maximum horsepower
  • Work against exhaust systems with restrictive back pressure
  • Power enhancement helps maintain top end speed for long distances
  • Intended for applications where low idle speeds are required
