Mahle Original Premium Piston Ring Sets
Mahle Original piston ring sets are designed to be installer-friendly. They are pre-lapped to seat immediately, virtually eliminating break-in time. Ring materials and coatings, as well as ring tension, are all optimized for reduced friction and extended life in each application. The compression rings feature a barrel-faced contact area for more efficient compression and CNC-controlled gap chamfer to optimize compression and reduce blow-by. Intermediate rings have a reverse twist design for better groove side sealing, and taper race machining to enhance contact. The CP-20 oil ring assemblies feature a 20 degree ear angle, an exclusive feature that provides the best possible side seal against the cylinder wall, and a special chemical polish on the oil ring expander offers enhanced oil drain back. Mahle Original piston ring sets provide unmatched quality and ease of installation, making them the rings of choice for today's engine builders.

Mahle PowerPak Pistons
Mahle PowerPak pistons are forged pistons with steel pins and wire locks. The pistons are hand-deburred and then coated with dry phosphate to protect against ring micro-welding and pin galling during initial startup. For additional performance, Mahle added its proprietary Grafal anti-friction coating to the piston skirts. Part numbers with T on the end have a cutting edge ceramic-based thermic barrier. The barrier is resistant to thermal shock, insulates the piston crown, and reduces heat transfer to increase performance. These replacement pistons are available in a wide variety of size options for fitment with specific engines and pistons.

CP Pistons CPK Piston Kits
CP Pistons CPK piston kits come complete with a piston, wrist pin, locks, rings, and gasket. The anti-detonation grooves, also known as contact reduction grooves, protect the top ring by disrupting detonation waves. These grooves also limit the piston/cylinder contact during high temperatures and rpm. The featured accumulator groove is a V-shape machined into the second ring to collect excess blowby between the top and second rings. The accumulator groove also collects residual gasses during combustion and alleviates top ring flutter, while increasing ring seal. Other features, such as double pin oilers, in conjunction with their dual fed reservoir, add twice the amount of oil from the cylinder wall to the wrist pin. CP wrist pins have fine grooves that are intrinsically engraved into the product surface at the time of machining. These grooves are transformed into micro-dimple indentations to act as oil reservoirs, and the oil that would normally drain away through the grooves on an untreated product still remains in the dimples. X-forgings minimize friction and reduce weight without compromising strength. CPK piston kits go above and beyond in both quality and dependability.

S&S Cycle Moly Faced Piston Rings
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.
