Mahle OE GMC Pass & Trk 250 Eng 1966-84 .060 Piston Set (Set of 6)

If you're rebuilding the engine in your classic GMC or Chevrolet truck, or even a variety of other vehicles from the late 60s through the early 80s, a quality piston set is crucial. This Mahle OE cast piston set is specifically sized at .060 inches undersize for the 250 cubic inch inline-six engine, a popular choice for many GM passenger cars and trucks from 1966 to 1984.

Mahle is a well-known OE supplier, meaning these pistons are built to the same standards as the original parts. They feature compensated ring grooves to ensure proper ring loading and effective oil control, which helps reduce blow-by and oil consumption. The expansion-controlled design means they're made to fit with minimal clearance, helping to quiet down engine noise and reduce wear over time. Plus, these pistons come ready to install with the piston rings already mounted, along with the necessary wrist pins and clips, saving you a step during your rebuild.
