What is the significance of the '.040' measurement on these pistons?

The '.040' indicates that these pistons are 0.040 inches larger than the standard bore size. This is common when an engine block has been bored out during a rebuild to clean up imperfections or achieve a specific clearance. You'll need to ensure your engine's cylinders are bored to this exact size for a proper fit.

Do these pistons come with everything needed for installation?

Yes, these Mahle OE pistons come ready for installation. They include the piston rings already mounted, along with the piston pin and clips, which simplifies the assembly process for the engine builder.

Are these pistons suitable for all 4.3L 262ci V6 engines from 1985-1995?

This set is designed for most 4.3L 262ci V6 engines within that range, but there are exceptions. Specifically, they are not for '6 Pack' configurations. It's always best to confirm your engine's specific configuration and refer to detailed fitment charts to ensure compatibility.

Product Details

If you're rebuilding the engine in your 1985-1995 GMC or Chevrolet truck or car with a 4.3L 262ci V6, these Mahle OE cast pistons are a solid option. They're designed to meet the original equipment specifications, ensuring a proper fit and function for your engine. This set includes six pistons, each measuring .040 inches undersize, ready to be installed.

Mahle pistons are well-built with features like compensated ring grooves. This helps ensure the piston rings load correctly and control oil effectively, which is crucial for engine longevity and performance. They also use expansion-controlled designs, allowing for tighter clearances when the engine is cold. This reduces noise, wear, and emissions while further improving oil control. Mahle is a major OE piston manufacturer, so you're getting parts that match what came from the factory.

This set comes with the pistons, pins, and clips already mounted, making installation more convenient for the engine builder. Just remember that these are not CARB approved and cannot be shipped to California.
