Technical Specifications and Features

The E-356K piston ring set features a precise 3.7360 inch bore diameter and outside diameter, matching standard size engine cylinders. The top ring is crafted from steel with a molybdenum coating, providing durability and resistance to wear under high temperatures. The second ring uses grey iron with a phosphate coating, enhancing its ability to retain oil and reduce friction. The reverse torsional face design on the second ring improves sealing efficiency by maintaining consistent contact with the cylinder wall. The oil ring is a 3-piece flex vent design with a 3/16 inch width, optimized for effective oil scraping and control to prevent excess oil consumption.

Compatible Vehicles and Applications

This piston ring set is compatible with a wide range of General Motors vehicles equipped with 8-cylinder engines and a 3.7360 inch bore size. It fits popular models such as the Chevrolet Camaro, Impala, and C10 trucks, as well as Buick LeSabre, Pontiac Firebird, and Cadillac Brougham. The E-356K is suitable for engine rebuilds or repairs requiring standard size piston rings in these vehicles.

Common Engine Issues Addressed
