Product Details

If you're rebuilding the top end of your 2017-2021 Harley-Davidson FLHTKSE CVO Limited or FLHXSE CVO Street Glide, these Wiseco piston ring sets are made to work perfectly with Wiseco pistons. Piston rings are crucial for a few key things: they seal the combustion chamber to maintain compression, they help control oil by scraping excess oil off the cylinder walls, and they transfer heat from the piston to the cylinder wall. Wiseco designs these rings specifically to meet their own high standards for performance and sealing, ensuring your engine runs as it should.

These rings are built for race-ready performance, meaning they're tested to handle the demands of a high-performance engine. The specific dimensions of this set are 4.060 inch bore size with ring thicknesses of 1.2mm for the top two rings and 3.0mm for the oil ring. Getting the right ring dimensions is critical for proper sealing and oil control, and these are designed to fit Wiseco's 4.060 bore pistons precisely.
