5.2L FSI Audi R8 Gen.2 & Lamborghini Huracan V10 High End Head Stud Kit

High End stud kit for the cylinder head for all 5.2L FSI V10 engines as build in the Audi R8 & Lamborghini Huracan.

A MUST for all engines which are running boost pressure and ARP is not yet stable enough!
BAR-TEK® studs have a hexagon socket to screw in the stud bolts. By a cone on the block side of the bolt, these are based on tightening the nuts not on the thread flanks, but in the bore of the thread in the engine block. This support protects the thread with frequent assembly of racing engines.

Made from ultra-pure 18.8 tool steel
All threads rolled for maximum strength
with neck cone for preloading for optimal distribution of forces on all threads
Hexagon 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® studs is that the nuts and washers included in the set also have a tensile strength of 1800 N / mm².

Up to 35% stronger stretch steel than ARP bolts.

including bag of moly paste
