DESCRIPTION
A piston oversized kit is a set of components used to replace the existing piston in an engine. The 4955548 kit includes a larger piston, rings, and wrist pin to increase the displacement of the engine. It is typically used for engines that have been damaged due to wear or overheating, and can also be used by performance enthusiasts who want to increase their engine's power output. The larger piston allows for more air and fuel to enter the combustion chamber, resulting in increased horsepower and torque. It is important to note that installing an oversized piston requires careful measurement and precise machining of the cylinder walls to ensure proper fitment and reliable operation.
