Mahle OE GM 4.8L / 5.3L 05-09 fits LMG LC9 LY5 & LMF 1.00MM Piston With Rings Set (Set of 8)

These Mahle OE cast pistons are built to the original equipment specifications for GM 4.8L and 5.3L V8 engines found in many trucks and SUVs from 2005 to 2009. They come in a set of eight, ready for installation with the piston rings already mounted, along with the necessary pins and clips. This makes the rebuilding process more straightforward, as you won't need to source those smaller components separately.

Mahle has engineered these pistons with compensated ring grooves. This design detail is important because it ensures proper ring loading, which directly impacts oil control and helps reduce blow-by. The pistons also feature an expansion-controlled design. This allows for tighter, smaller fitting clearances within the cylinder bore. What that means for your engine is reduced noise during operation, less wear over time, and potentially lower emissions, all while maintaining good oil control. Mahle is a major OE piston manufacturer, so you're getting a part built to the same standards as what originally came in your vehicle.

This set is designed for engines with a 1.00MM bore size. It's important to confirm your engine's specific bore size before ordering. This piston set fits a wide range of GM vehicles, including popular models like the Chevrolet Silverado, GMC Sierra, Chevrolet Tahoe, and GMC Yukon, among many others. Always refer to your vehicle's service manual or consult with a professional to ensure this is the correct part for your engine rebuild.
