About this product
Upgrade your engine's performance with the Prox Piston Kit, designed as a direct OEM replacement for reliable and consistent power. This kit provides all the necessary components for a complete piston replacement, ensuring your engine runs smoothly and efficiently. Experience the quality and precision of Japanese manufacturing with this high-performance piston kit.
Description
The Prox Piston Kit is manufactured in Japan to meet or exceed OEM specifications, guaranteeing a precise fit and optimal performance. Each piston is cast from a high-silicon-content aluminum alloy, providing exceptional strength and durability while minimizing weight. The piston is then CNC-machined to extremely close tolerances, ensuring perfect roundness and minimal friction within the cylinder. This meticulous manufacturing process results in improved engine efficiency, increased power output, and extended engine life. The standard size B designation indicates the piston's dimensions, designed for a specific range of cylinder bore diameters. This kit offers exceptional value and performance for enthusiasts and professionals alike. Installing a new piston kit improves compression, reduces oil consumption and restores lost engine power. It is a cost-effective solution for maintaining your engine's optimal condition and preventing more costly repairs down the road.
