Uprated cylinder head stud kit, designed to replace standard bolts

High strength heat treated studs allow an increased torque rating, therefore the ability to deal with high boost applications

Factory bolts yield strength – 12,000lbs
Uprated studs yield strength – 28,000lbs

Kit includes –
12x aviation class studs, nuts and washers

Studs fit the factory block with a 7/16th UNF top thread for increased CLAMPING pressure
Studs do not twist during the tightening process, allowing more accurate torque value and therefore a more even and accurate clamping force.

We advise a using a good quality head gasket such as Elring, which we can provide if required.
