Product Details
This Mahle OE ring set includes the necessary steel Napier piston rings for a 4.600 inch bore, with a 1.0mm top ring and a .136 inch ring width. These rings are crucial for creating a proper seal between the piston and cylinder wall, which is essential for engine performance and efficiency during a rebuild.
Mahle has designed these rings with a Napier hook on the second ring, which helps to control oil consumption and improve the seal against the cylinder wall, especially in applications where blow-by can be an issue. The steel construction offers good durability for the demands of an engine rebuild. Proper installation is key to ensuring these rings perform as intended, so be sure to follow the manufacturer's guidelines for setting end gaps and seating them correctly in the piston grooves.
