Mahle OE GM 4.2L 06-09 Piston Set (Set of 6)

If you're rebuilding the engine in your 2006-2009 GM inline-6 vehicle, a solid set of pistons is crucial. This Mahle OE piston set is built to the same standards as the original equipment, ensuring your engine runs smoothly and efficiently. They feature compensated ring grooves that help maintain proper ring tension and control oil, while expansion-controlled designs allow for tight clearances. This reduces engine noise, wear, and emissions, all while improving oil management.

Mahle makes installation easier by including these pistons with the rings already mounted. The set also comes complete with the piston pins and clips, so you have everything you need to get the job done. Mahle is a well-known OE piston manufacturer, and these pistons are a well-built option for your engine rebuild. This set fits a range of vehicles, including the Chevrolet Trailblazer, GMC Envoy, and Saab 9-7x.
