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. Our 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

Our 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.
