These High Energy hydraulic lifters from COMP Cams feature a patented, constant orifice-metering valve that precisely meters oil to the rocker arms. Continuous contact between the metering valve and the precisely coined bottom surface of the pushrod seat is maintained throughout the engine's rpm range, eliminating excessive oiling at high speeds. The pushrod seat is made of a special powdered metal iron alloy, heat-treated for strength and wear resistance. The longer piston is produced with through-hardened steel that provides more bearing surface and increased lifter longevity. These lifters have a lightweight check valve disk that allows for quicker response, resulting in increased engine speed before valve float.

If you are modifying your Harley® for increased horsepower or aggressive riding, S&S Cycle's Moly faced piston rings can be a good choice. The Moly coating material provides excellent friction reduction properties and can withstand high temperatures better than many other ring coatings, making it suitable for high-performance engines. The porous nature of the Moly coating helps to hold oil on the ring face, providing better lubrication during initial engine start-up and under heavy load. Moly rings often break-in more easily than other types of rings due to their coating properties. Even for everyday riding, Moly rings can offer improved engine longevity if you frequently push your bike hard. Order the Moly faced piston rings designed for your HD® model's engine type.

Valve guides on Harley-Davidson® motorcycles are essential for proper valve operation. S&S Cycle valve guides are designed to provide optimal engine performance by accurately aligning the valves, minimizing friction, dissipating heat generated during combustion, and preventing valve stem wear, ultimately leading to better power delivery, fuel efficiency, and engine longevity. The valve guides are typically made from materials like bronze or cast iron, each with its own wear characteristics and heat transfer properties and help to maintain the integrity of the combustion process by guiding the valves to open and close correctly. Select the S&S Cycle valve guides recommended for your bike's application needs. Features and benefits: * Proper valve alignment—valve guides precisely position the valve stems, allowing them to open and close correctly at the right time, crucial for efficient air intake and exhaust gas expulsion * Reduced friction—the smooth surface of a good valve guide minimizes friction between the valve stem and the guide, reducing wear and heat generation * Heat dissipation—the material of the valve guide is designed to conduct heat away from the valve stem, preventing excessive overheating which can damage the valve * Valve stem protection—by guiding the valve stem accurately, the valve guide prevents the valve from contacting other engine components, reducing potential damage * Improved engine performance—with proper valve operation facilitated by the guides, the engine can achieve optimal power and efficiency * Extended engine life—well-maintained valve guides contribute to a longer engine lifespan by minimizing wear on critical components like the valve stems and valve seats Important considerations regarding valve guides: * Material selection—valve guides are typically made from materials like bronze or cast iron, each with its own wear characteristics and heat transfer properties * Clearance—maintaining the correct clearance between the valve stem and the guide is vital to prevent excessive friction and wear * Regular maintenance—periodic inspections and replacements of valve guides are necessary, especially when experiencing symptoms like decreased engine power, excessive oil consumption, or unusual engine noises
