Porsche This newly re-designed connecting rod fits Porsche 356 / 912 models and supersedes Carrillo part number PR-912>-45352S and LN part number 400-912. Fully machined from a proprietary 4330M alloy forging for strength and durability, with added clearance for performance camshafts and stroker builds.

Features upgraded CARR-S7 (MP35N) bolts with a UTS of 285ksi. All our bolts are manufactured with asymmetrical threads, each thread has a slightly different design than the previous giving the bolts an evenly distributed thread engagement. This helps increasing the clamp load and fatigue life of the fastener.
