X-Beam Connecting Rod Set for Porsche 911 997 GT3 RS 4.0

Pauter X-beam connecting rods offer a balance of strength and weight reduction for Porsche 911 997 GT3 RS 4.0 engines. Constructed from E4340 vacuum-melt chrome-moly forgings, these rods are fully CNC machined and heat-treated to Rockwell C36. Each set features full coverage shot peening and is end-to-end balanced. They include ARP 2000 bolts, known for their 220,000 psi tensile strength, and durable aluminum-bronze wrist pin bushings. The unique X-beam design contributes to reduced horsepower loss by minimizing crankcase winding. For optimal performance on both street and track, it is recommended to run these Pauter rods with coated Clevite racing connecting rod bearings, which are sold separately. The connecting rods have a center-to-center length of 127.79mm, a large end diameter of 56.02mm, a big end width of 20.88mm, a small end diameter of 23.01mm, and a narrow end width of 23.47mm.
