Premium Enginetech Pistons | Coated Skirts | Floating Pins | Steel-Top Moly Rings | OEM+ Quality
This kit includes (8) Hyper-Eutectic Dish-Top Pistons with Floating Pins and a complete set of Premium Moly Piston Rings, designed for 2007–2010 Chevy/GMC 6.0L VORTEC V8 engines (LY6, L76, LFA – VINs 5, K, Y).
Built from high-silicon hyper-eutectic aluminum alloy, these pistons provide superior strength, heat resistance, and wear protection compared to cast pistons. With coated skirts, dual valve reliefs, and floating pins, they are engineered for long service life and reliability in both stock rebuilds and high-load applications.
The included Premium Steel-Top Moly Rings are precision-engineered for maximum compression sealing, oil control, and heat transfer — essential for today’s hotter-running engines.
