Review SCREAMIN EAGLE Piston Kit

The Screamin' Eagle 21900079 Piston Kit is a premium upgrade for Harley-Davidson Touring model engines, designed to deliver enhanced power, increased durability, and improved engine performance. This kit is engineered to fit select Harley-Davidson Touring motorcycles, including those with Twin Cam 103, 110, and 114 engines.

Each piston in this kit is precision-machined from forged aluminum, ensuring superior strength and reliability. The piston crowns are engineered with a dish shape and a domed top ring land, which optimizes ring sealing and improves engine compression. Additionally, the piston skirts feature a unique design that minimizes friction and reduces heat transfer to the cylinder walls, contributing to a cooler-running engine.

The piston rings included in the kit are made of high-performance materials, such as chrome molybdenum alloy for the top rings and nitrided steel for the second and oil control rings. This combination provides excellent sealing and wear resistance, ensuring a longer service life and improved engine performance.

The piston pins are made of high-tensile steel and are nitrided for increased strength and durability. They are also phosphate-coated to prevent galling and seizing. The piston pin bushings are made of high-performance materials, such as sintered bronze, and are designed to provide a smooth fit and long-lasting performance.

The piston kit also includes ring gaps sets, which are specifically designed for each piston size to ensure optimal ring clearance and proper sealing. The kit also includes new piston pin retaining clips, which are made of high-strength steel and are designed to provide a secure fit and prevent piston pin movement during engine operation.

The Screamin' Eagle 21900079 Piston Kit is backed by Harley-Davidson's one-year limited warranty and is proudly made in the USA. Installing this kit requires some mechanical expertise and the appropriate tools, so it is recommended that the installation be performed by a professional technician. By upgrading to this premium piston kit, Harley-Davidson riders can experience improved engine performance, increased power, and enhanced durability for their Touring model motorcycle.
