VAG High End stud bolt Gold Series cylinder head BAR-TEK®

High-end stud bolt kit for the cylinder head for many VAG engines Thanks to our subsequent treatment, we were able to increase the tensile strength even further and now achieve justover 1900 N/mm². If you want the strongest bolts for your engine, you've come to the right place.You can't get any stronger! A MUST for all engines that run at high boost pressure and for which ARP is not yet stable enough!Thanks to a cone on the block side of the studs, they are not supported on the thread flanks when the nuts are tightened, but in the bore of the thread in engine block. This support protects the threads during frequent assembly of racing engines.
