What does '.060 over' mean for these pistons?

'.060 over' means these pistons are 0.060 inches larger in diameter than the original factory pistons. This size is used when the engine's cylinder walls have been worn down and need to be bored out to match the larger piston size for a proper seal.

Do these pistons come with everything needed for installation?

Yes, this set includes the pistons, piston rings, wrist pins, and clips. They are ready to be installed right out of the box, which simplifies the engine building process.

What is the benefit of compensated ring grooves?

Compensated ring grooves help ensure that the piston rings are loaded correctly against the cylinder wall. This leads to better oil control, preventing oil from entering the combustion chamber, and helps maintain consistent compression.

Product Details

Mahle is one of the largest original equipment piston manufacturers in the world, and they're known for making parts that meet or exceed factory specs. This piston set is built to OE quality for your GMC or Chevrolet 350 cubic inch, 5.7-liter engine from 1967 to 1985. These pistons are .060 inches over, meaning they're slightly larger than stock to help restore compression in engines with worn cylinders.

What's neat about these Mahle OE pistons is how they're designed to help your engine run smoother and last longer. They feature compensated ring grooves, which make sure the piston rings seal properly against the cylinder wall for good oil control and consistent compression. Plus, their expansion-controlled designs mean they can be fitted with very little clearance, which helps reduce engine noise, wear, and emissions. This set comes with the pistons, rings, pins, and clips all mounted and ready to go, saving you time during your rebuild.

This set is a solid option for many vehicles from the late 60s through the mid-80s, including popular models like the Chevrolet C10 Pickup, Chevrolet Camaro, and GMC Jimmy. It's a great choice for anyone rebuilding a classic V8 engine and looking for parts that perform like the originals.
