    • Part: Sealed H857CP engine piston
    • Fits: 1999-2003 Chevrolet Silverado 2500 V8 6.0L and other vehicles

    Worn pistons and rings can show up as blow-by, oil burning or lower compression. Worn rings, a scored cylinder wall or a leaking head gasket can be behind those signs too, so find the cause before buying pistons. The 6.0L V8 takes eight, one per cylinder.

    The 2001-2003 GMC Sierra 1500 V8 6.0L and the 2001-2003 GMC Yukon V8 6.0L are also a fit for this piston, along with other vehicles.
