Wagner Tuning Pro Series main stud kits are must-haves for all engines that run with increased boost pressures. They replace the original main bearing bolts with high-strength Pro Series 18.8 stud bolts with a tensile strength of 1850 N/mm², and they do not need to be replaced after disassembly, but can be reused. Pro Series bolt threads are formed and not cut as is customary in the trade. By rolling the threads, the strength of the tooth flanks can be increased by around 30 percent. All Pro-Series products are supplied with a nickel coating or a burnished finish and are therefore protected against corrosion in the long term, even under the toughest conditions. Pro Series stud bolts have a hexagon socket drive on the head side for screwing in the stud bolts. Thanks to a cone on the engine block side of the stud, these are not supported on the thread flanks when the nuts are tightened, but in the bore of the thread in the engine block. This support protects the threads during frequent assembly of racing engines. Nuts and washers are included in each set, and they also have a tensile strength of 1850 N/mm². Select the kit designed for your vehicle in the finish you prefer best.
