FULL DESCRIPTION

ProX Connecting Rod Kit

The ProX Connecting Rod Kit is engineered to provide an exact, high-performance replacement for your engine. Manufactured by leading Japanese OEM factories, these kits are designed to meet or exceed strict OEM specifications, ensuring a reliable and cost-effective solution for your engine rebuild.

Each connecting rod is produced using a double forging process on dedicated forgings. This advanced manufacturing technique improves grain flow, which results in superior structural strength, enhanced durability, and consistent dimensional accuracy. To further increase longevity and performance, the rods undergo shot peening and barrelling processes. These treatments eliminate residual stress and create a smooth surface texture that helps the component withstand extreme operational conditions.

Key Features

  • Precision Engineering: Manufactured in Japanese OEM factories to ensure exact OEM specifications and fitment.
  • Double Forged Construction: Provides improved grain flow for maximum strength and dimensional consistency.
  • Surface Finishing: Shot peening and barrelling techniques remove residual stress and optimize the surface for high-performance use.
  • Advanced Oiling System: Each kit features precisely located oiling slots designed to maximize lower rod lubrication, which significantly extends the lifespan of the bearings.
  • Complete Kit: Supplied with the connecting rod, crankpin, big-end bearing, small-end bearing, and necessary washers for a comprehensive installation.

Whether you are performing a standard engine refresh or a high-performance build, the ProX Connecting Rod Kit delivers the reliability required to keep your engine running smoothly under demanding conditions.
