Introducing the WiseCo 4722P3 Flat Top Piston for Harley-Davidson applications, a high-performance upgrade designed to deliver exceptional power and durability. This piston is specifically engineered for Harley Davidson engines using a 3.528-inch (89.5mm) bore size and 0.30-inch (7.6mm) piston crown height.

Crafted from forged 2618-T6 aluminum alloy, this piston boasts a flat-top design with a 0.30 over-bore.

The WiseCo piston's skirt is designed with a full-length, split-ring oil scraper ring groove. This feature effectively collects and channels oil to the crankshaft for proper lubrication, reducing friction and wear. Additionally, the piston's second ring groove accommodates an optional oil control ring, which further reduces oil consumption and prevents crankcase pressure buildup.

The piston's pin bosses are designed with a large pin bore to accommodate aftermarket connecting rods with oversized pins. This allows for increased strength and durability, ensuring the piston can withstand the demands of high-performance applications.

Each WiseCo piston undergoes stringent quality control measures, including 100% magnetic particle inspection for cracks and defects. The piston is then balanced and machined to ensure proper fit and function within the engine.

Upgrading to the WiseCo 4722P3 Flat Top Piston provides significant benefits for Harley-Davidson enthusiasts seeking increased power, improved engine response, and enhanced durability. With its high-quality materials, precise machining, and rigorous testing, this piston is an excellent choice for serious performance enthusiasts.
