Product Details
If you're rebuilding the top end of your GM 6.6L Duramax diesel, getting the right piston rings is crucial for sealing the combustion chamber. This Mahle top ring is designed for the DMAX forged piston, new style, and is a single cylinder set. It's built to handle the pressures and heat of diesel operation, helping to ensure your engine runs efficiently and powerfully.
Mahle is a well-known name in engine components, and these rings are made to precise specifications. The 1/16 inch width is standard for many diesel applications, and this set is for a standard bore size, meaning it's ready to go in without needing to machine the cylinder walls further if they are still within spec. Proper ring installation is key to a good seal, so make sure to follow the manufacturer's guidelines when putting your engine back together.
