A-B1793560-AI PISTON ASSEMBLY

One New Aftermarket Replacement Piston Assembly Fits Briggs and Stratton Small Engines

This aftermarket replacement piston assembly Fits Briggs and Stratton (B&S) small gasoline engines in the 400000-699999 engine series. The piston assembly is a core internal engine component located in the cylinder bore, responsible for compressing the air-fuel mixture and transferring combustion force to the connecting rod. Replacing a worn or damaged piston assembly restores proper compression, reduces oil consumption, and returns the engine to full power output. This is a standard (STD) bore size replacement.
