Mahle OE GMC Pass & Trk 250 Eng 1966-84 .030 Piston Set (Set of 6)

If you're rebuilding the engine in your 1966-1984 GMC truck or passenger car with the 250 cubic inch inline-six, this Mahle OE piston set is a solid option. These are cast pistons, sized .030 inches over the standard bore, and they come ready for installation. Mahle is one of the world's largest original equipment piston manufacturers, so you know you're getting parts that meet the same standards as what came from the factory.

What sets these pistons apart is their attention to detail for proper engine function. They feature compensated ring grooves, which help ensure the piston rings seat correctly and control oil. The expansion-controlled design also means they're built to run with minimal clearance, helping to reduce engine noise, wear, and emissions while improving oil control. This set includes six pistons, each with its piston ring set already mounted, along with the necessary wrist pins and clips, making your engine build a bit more straightforward.
