Piston Ring Set 4.040 Moly 1/16 1/16 3/16

The Piston Ring Set 4.040 Moly 1/16 1/16 3/16 from JE PISTONS is designed for high-performance engine builds where precision ring seal and durability are crucial. This set is ideal for those rebuilding stroked small-blocks or restoring classic muscle engines, providing the compression control and blow-by reduction needed for a robust engine build.

Featuring a bore diameter of 4.040 inches, this ring set includes two 1/16-inch compression rings and one 3/16-inch oil control ring, optimizing sealing efficiency and reducing friction. The molybdenum facing on the compression rings enhances scuff resistance during startup and high-load conditions, protecting against bore wear. The stepped oil ring design improves oil scraping capability while maintaining optimal film thickness on the cylinder walls.

This piston ring set is particularly beneficial for serious engine builders and enthusiasts who demand high performance and reliability. It is suitable for a variety of applications, especially in engines running elevated boost levels or high RPMs, where standard rings may fall short.
