Good To Know
Q: Is this piston kit compatible with high-mileage cylinders? A: Yes, but measure the cylinder bore to ensure it is within spec for a standard size piston. If the cylinder is worn beyond limits, boring may be required.
Q: What is the difference between Size A and Size B? A: Size A and B indicate slight variations in piston skirt diameter to accommodate different cylinder tolerances. Use the grade that matches the engine's original specification.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
