Product Details
Audi S4 B9 3.0 T OEM Pro-Series 18.8 main bearing stud bolt set
This set replaces the original main bearing bolts with high-strength Pro-Series 18.8 stud bolts. A MUST for all engines that run with increased boost pressure! The Pro-Series 18.8 stud bolts with a tensile strength of 1850 N/mm² provide a remedy. In addition, these stud bolts do not need to be replaced after disassembly but can be reused.

Assembly instructions
Tensile strength:
PS 18.8 steel
1850+ N/mm² (270,000+ PSI)
High-quality materials and production
The Pro-Series 18.8 sets are high-strength stud bolts made in Germany. A special steel is used, which has a tensile strength of 1850+ N/mm² after tempering. All 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%. All Pro-Series products are supplied with a nickel coating or optionally with a burnished finish and are therefore protected against corrosion in the long term, even under the toughest conditions.
Easy installation and durability
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. A major advantage of Pro-Series over other manufacturers is the nuts and washers included in the set, as these also have a tensile strength of 1850 N/mm².
