MAHLE piston pin lock rings are manufactured from high-quality spring steel to provide reliable retention force while withstanding the extreme temperatures and stresses of engine operation. The round wire design distributes load evenly around the groove circumference, preventing pin migration and ensuring long-term durability. These lock rings are essential components during engine rebuilds and piston replacements.
