Review MID USA Set Moly 8.5 Piston Kit For Harley Inch fits SHOVELHEAD PANHEAD STD 1200 1974

The 62156 Moly 8.5 STD Piston Kit is specifically designed for Harley-Davidson Shovelhead and Panhead engines manufactured between 1974 and 1985 with a displacement of 1200cc. This piston kit is an excellent upgrade for those seeking improved engine performance, durability, and reliability.

Each piston in this kit is meticulously crafted using a forged design for superior strength and rigidity.

This coating is particularly beneficial for high-performance applications and environments where the engine may be subjected to extreme temperatures or heavy usage.

The 8.5:1 compression ratio of these pistons provides a balance between power and efficiency. This ratio allows for increased power output while maintaining adequate fuel economy. The pistons are also designed to work seamlessly with the stock Harley-Davidson heads and intake manifolds, ensuring a straightforward installation process.

To ensure proper fitment, each piston is accompanied by its corresponding ring set, including a compression ring, oil control ring, and skirt oil scraper ring. The rings are precision machined from high-quality steel for optimal performance and longevity. The kit also includes new piston pins and wrist pin bushings.

This piston kit is an excellent choice for riders looking to enhance the performance of their Shovelhead or Panhead Harley-Davidson motorcycle. With its forged design, molybdenum coating, and high-compression ratio, the 62156 Moly 8.5 STD Piston Kit delivers increased power, reliability, and durability for your Harley-Davidson engine.
