Description

High End stud bolt Kit for the cylinder head for all 5.2L FSI V10 like in the Audi R8 and Lamborghini Huracan.

A MUST for all engines that run with charge pressure and ARP is not stable enough yet!
BAR-TEK®  stud bolt have a hexagon socket to screw in the stud bolt. Due to a cone on the block side of the bolts, they are not supported 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 maximum strength
  • with tapered end for preloading for optimum force distribution 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

A major advantage of the BAR-TEK®  stud bolt is that the nuts and washers included in the set also have a tensile strength of 1800 N/mm² .

Up to 35% stronger elongated steel than ARP bolts.

Tightening torque in 3 steps like series. Last stage 110 Nm.

incl. bag of Moly Paste
