R&R Rro Billet 4340 Chromoly Steel
Connecting Rods

For more than a decade, R&R Racing Products has been manufacturing the highest quality precision engineered billet race components, from their Pro-series connecting rods to our dry sump oil pumps and injector assemblies. While other manufacturers attempt to dominate the market by mass producing their rods and selling them at cutthroat prices, R&R has taken a different approach. R&R Racing Products is dedicated to continuously improving its connecting rods and other products by actively seeking out new technologies, processes, and stronger materials, thereby standing up to their promise of exceeding and outperforming the competition time and time again. Independent and thorough bench and field testing of both our alloys and finished product performed by R&R places the utmost importance in ensuring the best set of connecting rods money can buy.

The same can be said of R&R’s newest line of Pro billet steel connecting rods, available for imports and domestics and exclusively for Porsche from LN Engineering LLC. For non-Porsche applications, call R&R Racing Products directly at 815-465-6741.

R&R starts with the highest grades of E4340AQ Chromoly, exceeding the specifications of 300M steel which is then machined in our state of the art CNC facility. Each and every connecting rod has been engineered for the ultimate balance of strength and weight, heat treated, cryogenically treated, triple tempered, shot-peened, quality tested, and then finally assembled with the finest ARP 2000, L19, and Custom Age 625 fasteners, precision honed, and balanced to industry specification, right out of the box.

The above finite element analysis shows our "winged" design, which reinforces the weakest area of the rod in this case, at the rod bolt head shoulder.
