Pro Rods are designed for improved performance over OEM components. They offer superior strength and durability, leading to an overall longer life span for each rod. Pro Rods can withstand more punishment without failure, especially under extreme conditions and in racing applications, making them a sure choice for those looking for a more durable and better-performing engine.
Pro Rods Choice Alloy
Four years worth of research and testing with different composite materials led to the final choice of an aerospace-grade alloy for use in these supreme connecting rods. This innovative material has been chosen for its superior properties which allow it to meet the extreme demands of the high performance engines used in the power sports industry.
Pro Rods start out as waterjetted blanks that are machined in CNC mills using sophisticated 3D CAD designs. Many of our rods are the result of designs that are put through extensive FEA testing and real-world experiences. The rods are then deburred in a vibratory deburring tank to further reduce any stress risers and to help smooth any imperfections.
Pro Rods rods start with a copper plating of the non-critical areas. They are then heat treated to stringent specifications by a Nadcap, ISO, and AMS certified heat treating facility. This process substantially hardens the rods for increased strength. From there, the rods are stripped of their copper plating so that they can be properly shot-peened.
The rods go through a shot peening process to enhance both their strength and flexibility characteristics. Shot peening increases strength of the components by approximately 30%, allowing them to withstand constant flexing and abuse over a longer duration.
Every batch of rods receives an assigned batch number that is laser etched on the surface to track material and heat treating specifications. The laser etching also includes the general dimensions for each rod, including their center-to-center length, and the signature Pro Rods logo.
NOTE: Crankpin, bearing, and thrust washers are sold separately.
