Mahle Rings Performance Steel Napier 2nd Ring 3.4646in x 1.2MM .135in RW Plain Ring Set

Mahle OE offers this performance steel Napier 2nd ring set, part number 3021334. These rings are designed for specific engine applications where improved sealing and performance are needed. The Napier hook design in the second ring helps to control oil and maintain a good seal against the cylinder wall, especially during the power stroke.

Constructed from durable steel, these rings are built to withstand the demands of an engine rebuild. The 1.2mm thickness for the second ring and the .135 inch height are precise measurements critical for proper piston function. This set is intended for use in engines where a standard ring might not provide optimal performance or oil control under specific operating conditions. Always ensure you are using the correct ring set for your specific engine build to achieve the best results.
