What does '.040 undersize' mean for these pistons?

'.040 undersize' means these pistons are manufactured to be 0.040 inches smaller in diameter than the standard bore size. This is typically used when the engine cylinders have been bored out to a larger size during an engine rebuild.

Do these pistons come with everything needed for installation?

Yes, this set includes the pistons with the piston rings already mounted, as well as the necessary wrist pins and clips. This makes them ready for installation right out of the box.

Are these pistons suitable for a performance build?

These are Mahle OE (Original Equipment) pistons, meaning they are built to the same specifications as the factory parts. They are well-suited for a stock rebuild or a mild performance build where OE quality is desired.

Product Details

When you're rebuilding the top end of your 1990-1996 Chevrolet Corvette's 5.7L engine, starting with a solid set of pistons is key. This set from Mahle OE is manufactured to the same standards as the original equipment your car came with, ensuring a proper fit and function. They feature compensated ring grooves, which help manage oil control and ensure the piston rings seat correctly. This is important for maintaining good compression and preventing oil from entering the combustion chamber.

Mahle has designed these pistons with expansion control, allowing for tighter clearances when the engine is cold. This reduces engine noise and wear, and helps keep emissions and oil consumption in check. For your convenience, this set comes with the piston rings already mounted, along with the necessary pins and clips. This means they're ready to go straight into your build, saving you time and effort during the assembly process. Mahle is a well-known OE piston manufacturer, so you can trust the quality of these components for your Corvette's engine.
