Connection rod kit | ProX

Product description

ProX Connecting Rod Kits are made out of the toughest alloys available today and are made in Japan! O.E.M specifications and tolerances are meticulously maintained, a guarantee for easy installation and trouble free performance.

Double forged on dedicated forgings:
This process maintains superior strength, durability and dimensional consistency through improved grain flow.

Shot peening & barrelling:
The design of a connecting rod is very important to guarantee the lifespan and the performance. ProX connecting rods are barrelled and shot peened to improve the surface texture. Shot peening eliminates residual stress and smoothly blends the forging surfaces.

Oiling system:
ProX oiling slots are precisely located to maximize lower rod oiling and extend bearing life. Even under the most extreme conditions the rod will do its job. ProX Connecting Rod Kits come complete with Crankpin, Big-End Bearing, Small End Bearing and Washers.
