PROX Piston Kit 01.4223.B

A piston kit is fundamental to engine longevity and performance—worn or damaged pistons compromise compression, increase blow-by, and accelerate engine wear. The PROX Piston Kit 01.4223.B delivers OEM-equivalent quality without the OEM price tag, using precision engineering and high-silicon aluminum alloy construction to ensure reliable operation under demanding conditions. This complete kit includes everything needed for a full refresh: pistons, rings, wrist pins, and circlips.
