These are best quality connecting rods available on the market today. Our Super-duty H-beam designed, forged 4340 chromoly race rods come complete with heavy-duty ARP rod bolts. These are the perfect rods for any Hi-performance VW engine. This race proven H-beam design combines weight savings and super high strength because of their forged chromoly construction, heat treated, CNC machined, and stress relieved. Radiused rod caps help reduce the amount of clearanced required to the engine case when stroker crankshafts are used so you can run strokes up to 76mm without case clearancing. Included with every set of rods are a complete set of Genuine MADE IN THE USA ARP 190,000 PSI tensile strength rod bolts and are sold in matched balanced sets of four.
A note about rod lengths. We offer 4 different rod lengths because rod ratios are very important. Most engine builders today agree that longer rods produce more power, and less wear on internal engine components than shorter rods. Top engine builders try to achieve a rod ratio of approx. 1.6-1.8 to 1. A 82mm stroker crank should have a rod that is 145mm (5.7inches) to achieve a 1.76 rod ratio.
