Description

The Cummins Piston Ring Set 3802234 (1.00 mm oversize) is a precision-engineered replacement designed for diesel engines that have undergone significant cylinder boring during professional rebuilds. This ring set directly replaces OE Cummins part number 3802235 , providing OEM-level sealing performance, durability, and fitment. Manufactured for use in Cummins diesel engines , this 1.00 mm oversize piston ring set is ideal when standard or smaller oversize rings can no longer maintain proper compression. It restores combustion efficiency, reduces blow-by, and ensures consistent oil control under heavy-duty operating conditions. Each ring is produced from high-strength, wear-resistant materials and precision-machined to seat correctly against freshly bored cylinder walls. The optimized ring profile promotes stable compression, lower oil consumption, and extended cylinder life, even in high-load commercial and industrial diesel applications.
