Mahle Rings Ford Trac 201 CID 3.3L 201 Ford 3 Cyl Diesel 4.406in Bore Eng 256 Sleeve Assy Ring Set

This Mahle OE ring set is built to a 4.406 inch bore size and is 0.020 inches undersize, specifically for Ford 201 CID (3.3L) 3-cylinder diesel engines that use a 256 sleeve assembly. When you're rebuilding the engine in your Ford Trac, getting the right ring set is crucial for proper sealing and compression. Mahle is a well-known name in engine components, and this set is designed to meet the original equipment specifications for your diesel engine.

Properly installed piston rings create a seal between the piston and the cylinder wall, which is essential for maintaining compression, controlling oil consumption, and dissipating heat. This set is made to fit the specific bore dimensions required for the 3.3L diesel engine, ensuring it works correctly with the pistons and cylinder sleeves. Using an undersize ring set like this one is common when cylinder walls have been honed or bored to correct for wear or damage, allowing you to maintain the correct piston-to-wall clearance.
