FULL DESCRIPTION

ProX Connecting Rod Kit

The ProX Connecting Rod Kit is engineered to provide an exact, high-performance replacement for your engine's internal components. Manufactured by leading Japanese OEM factories, these rod kits are designed to meet or exceed original equipment specifications, offering a reliable and cost-efficient solution for engine rebuilds.

Each connecting rod is double forged on dedicated forging dies, a process that ensures superior strength, enhanced durability, and excellent dimensional consistency through improved grain flow. To further increase component longevity, the rods undergo precision shot peening and barrelling. These processes effectively eliminate residual stress and create a smooth, refined surface finish.

Key Features:

  • Advanced Oiling System: Precision-located oiling slots maximize lubrication to the lower rod, significantly extending the lifespan of the bearings even under extreme operating conditions.
  • Superior Strength: Double forged construction provides structural integrity and consistent performance for demanding engine environments.
  • Precision Surface Treatment: Shot peened and barrelled finish ensures a smooth surface texture and reduced stress concentration.
  • Complete Kit: Includes the connecting rod, crankpin, big-end bearing, small-end bearing, and necessary washers for a comprehensive installation.
  • Reliable Engineering: Designed to maintain OEM dimensional standards for a direct fit and optimal engine balance.

Whether you are performing a routine maintenance overhaul or a high-performance engine build, ProX Connecting Rod Kits provide the reliability and precision required to keep your engine running at its best.
