Do these pistons come with everything needed for installation?

Yes, this set includes the pistons, pre-mounted piston rings, wrist pins, and clips. They are ready for installation, which simplifies the engine building process.

Product Details

Mahle is one of the largest OE piston manufacturers in the world, known for making parts that meet original equipment specifications. This piston set is built to OE quality for GM 5.7L 350 V8 engines, offering a solid option for rebuilding or replacing worn components. These are a .030 inch undersize set, meaning they are machined slightly smaller than standard to account for cylinder wall wear or previous machining.

Each piston features compensated ring grooves to ensure proper ring loading and effective oil control, which helps reduce blow-by and oil consumption. The expansion-controlled design allows for minimal clearance within the cylinder bore, leading to quieter engine operation, reduced wear, and improved emissions. This set comes complete with mounted piston rings, wrist pins, and clips, making them ready for installation right out of the box, saving you time and hassle during your engine build.

This piston set fits a wide range of GM vehicles from the early 1980s through the mid-1990s, including models like the Chevrolet Corvette, Chevrolet C1500, and Buick LeSabre. Always check the full fitment guide to confirm compatibility with your specific vehicle.
