Description

High End stud bolt Kit for the cylinder head for all 2.5L TFSI EA855Evo engines as in Audi RS3 8V & TTRS 8S

A MUST for all engines that drive with high charge pressure and ARP is not yet stable enough!
BAR-TEK®  stud bolt have a Innensechantzum to screw in the stud bolt. Due to a cone on the block side of the bolts, they do not rest on the thread flanks when tightening the nuts, but in the bore of the thread in the engine block . This support protects the threads during frequent assembly of racing engines.    

  • Manufactured from ultra pure 18.8 tool steel
  • All threads rolled for highest possible strength
  • with shoulder cone for preloading for optimum distribution of forces on all threads
  • Hexagon socket drive for easy installation
  • Tensile strength over 1800 N/mm² (270,000 psi)
  • Nickel coating for outstanding corrosion protection
  • reusable

Up to 35% stronger expansion steel than ARP bolts.
