RWA1566-1 2.0 Gapless ring set STD 3.575″ bore. These are the gapless top ring set.
Total Seal® pioneered Gapless® technology over 50 years ago. Our Gapless® piston ring design provides consistent performance that doesn’t fade with opening end gaps. They are used for all aspects of Motorsports, Diesel, Industrial, Compressors and Aviation.
A Gapless® top provides the greatest performance benefit (increased horsepower and crankcase vacuum). However, a Gapless® 2nd provides excellent oil control and blow-by prevention (less oil consumption).As such, we typically recommend a Gapless® top for naturally aspirated applications, especially V8 and straight engines.For flat (horizontally opposed) engines and turbo or surper-charged engines, we recommend a Gapless® 2nd.Most Total Seal® piston ring styles are available in Gapless® configurations.
