FULL DESCRIPTION
ProX Connecting Rod Kit
The ProX connecting rod kit is engineered to meet or exceed strict OEM specifications, providing a reliable and cost-effective replacement for your engine's internal components. Manufactured by leading Japanese OEM factories, these kits are designed to ensure consistent performance and longevity for high-performance off-road applications.
Advanced Engineering and Durability
Each connecting rod is double forged using dedicated forging processes. This specialized technique maintains superior strength and durability by improving the grain flow of the metal, ensuring dimensional consistency throughout the component. To further enhance performance, the rods undergo shot peening and barrelling processes. This treatment improves the surface texture, eliminates residual stress, and effectively blends forging surfaces to create a highly resilient part.
Optimized Performance Features
ProX has carefully considered the demands placed on engine internals under extreme conditions. The kit includes precision-located oiling slots designed to maximize lower rod lubrication, which significantly extends bearing life. Each kit is supplied as a comprehensive package, including the connecting rod, crankpin, big-end bearing, small-end bearing, and necessary washers.
