Product Details
This set includes Mahle OE Piston Rings, specifically the Performance Steel Napier THM-13 model. These rings are designed for a 4.135 inch bore with 1.5mm top ring, 1.5mm second ring, and a 3.0mm oil ring, featuring a .150 inch wall thickness for the oil ring. They are a plain ring set, meaning they don't have special coatings but are built for reliable performance in engine rebuilds.
Mahle is a well-known name in engine components, and this steel Napier ring set is a solid option when you're putting an engine back together. The Napier hook design on the top ring helps with oil control and blow-by, which is important for maintaining good compression and preventing oil from getting into the combustion chamber. This helps ensure your engine runs smoothly and efficiently after the rebuild.
