Mahle Rings A C Engs A C Trac 426 CID 7.0L D3400/D3500/D3500 MKII 6 Cyl 4.250in Sleeve Assy Ring Set

If you're rebuilding the engine in your D3400, D3500, or D3500 MKII with the 426 CID 7.0L 6-cylinder engine, getting the cylinder sleeves seated correctly is a critical step. This sleeve assembly ring set from Mahle OE is designed to help ensure a proper seal between the piston and the cylinder wall. A good seal is essential for maintaining compression, preventing oil from entering the combustion chamber, and keeping exhaust gases from blowing past the piston.

Mahle OE is known for making well-built engine components, and this ring set is no exception. It's made to fit the 4.250-inch bore size, which is specific to these engines. Proper installation of these rings, along with the sleeves, is key to the longevity and performance of your rebuilt engine. Make sure to follow the manufacturer's installation instructions carefully to achieve the best results.
