Detailed Description

Mahle Part Number S224-2897.020 is an oversized engine piston engineered to OE standards for rebuilds that require accurate bore matching and dependable sealing. The expansion-controlled aluminium design helps maintain small fitting clearances, which supports quieter operation, reduced wear, and improved oil control. The Ricardo bowl piston head is suited to diesel combustion chamber requirements, while the compensated ring grooves help maintain proper ring loading during operation. This part cross-references General Motors 12550062 for the same application.

Compatible With 1992-2004 Chevrolet and GMC truck, van, and SUV platforms, this piston is used in applications such as Chevrolet Express 2500, GMC Savana 3500, Chevrolet K3500, GMC C2500 Suburban, and Hummer H1. The part number S224-2897.020 is also a useful reference when ordering for GM engine rebuilds that require a 0.020 in. oversize piston.
