Mahle Rings Ford Trk 359/361/389/391 Engs 74-81 Chrome Ring Set

These Mahle piston rings are 0.040 inch undersize, meaning they are designed to fit pistons that have been bored out slightly larger than their original factory size. This is a common practice when rebuilding an engine to ensure a proper seal and optimal performance. Mahle piston rings are built to meet original equipment requirements, focusing on reducing friction and minimizing oil consumption for a longer service life. They are a well-built option for rebuilding Ford truck engines like the 359, 361, 389, and 391 found in models from 1974-1981.

The chrome plating on these rings helps them resist wear and maintain their sealing ability over time, even under demanding conditions. This advanced design contributes to improved engine efficiency and durability. Mahle's focus on the latest piston ring technology ensures you're getting a part that performs well and lasts.
