These Extreme Black Severe Application valves by Howards Cams are engineered for high-rpm and high-horsepower applications. They feature a gloss black nitride finish and are perfect for high temperatures (they run cooler, which improves valve life), nitrous, turbo, and supercharger applications. These valves will give naturally aspirated motors a much greater cylinder flow for good horsepower gains. These valves start off as a one-piece forged high-temperature, high-nickel, stainless steel alloy. They're CNC-finished to strict tolerances, making them the choice for the most demanding race classes. Their black nitride micro-hardness is higher than the stainless steel base material. No process can match it for surface hardness! The surface finish is smoother than with chromed stems, having less friction between the stem and the guide. The black nitride reduces power loss due to there being less valve-guide friction. Their nitride finish is not a coating--it's a process whereby it actually becomes part of the steel, making them ideal for the most demanding applications.

For racers and engine builders who run both camshaft belt drives along with the Jesel front mount distributor, front drive combos incorporate the two units into one convenient, value-packed part number--and it's available for the company's most popular applications. Why choose the combination? Fast and easy intake manifold changes. More efficient plug wire routing. And it isolates cam torsional deflection. With a much cooler mounting location, there's no interference with manifold runners, windshield, or firewall areas. As with all Jesel distributor drive systems, a crank trigger type firing system and an external ignition box are required.

Feuling Parts HP+ lifters are a great performance upgrade for your motorcycle--as the name implies, they're "Horsepower Plus!" Hydraulic roller lifters provide optimized (and cooler) oil flow to top-end valves, springs, rockers, shafts, and valve guides. The rollers reduce friction between the lifters and camshaft, extending the life of your valvetrain gear. HP+ lifters are CNC-machined, precision-ground, drop-in replacements for your stock lifters. They've been dyno-developed and track-tested for use with the Feuling oil pump or comparable high-volume models. HP+ lifters are available to fit a variety of bike makes and models, including Buell and Harley-Davidson®.
