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.

SKF Bearings Speedi-Sleeves save time and money in your manual transmission maintenance. No shaft disassembly or machining! These thin-walled shaft repair sleeves are simply pushed in position over the worn area, providing a counterface surface that is optimized for radial shaft seals. Since the same sized seal as the original can be used, there's no need to search for other seals or to keep a stock of different sizes. No special equipment is required since the installation tool is supplied with the Speedi-Sleeves. A mallet and a pair of pliers are all you need for the installation. These replacement parts use a proprietary stainless steel material and manufacturing process, resulting in an optimized seal counterface surface that minimizes wear on both sleeve and sealing lip. The proprietary material provides increased strength and excellent ductility properties of the sleeve. Imperceptible lubricant pockets enable the lubricant to reside on the sleeve and thereby prevent dry running of the sealing lip that otherwise can create excessive wear. Order the size recommended for your vehicle and transmission application.
