Lancia Delta HF integrale - M12 Heavy Duty Head Stud Kit

Applications

The ARP M12x1.75 head stud kit is dedicated to high horsepower applications. Bolt Torque possible up to 149Nm. We don't recommend using it, if you're not intended to go for real high boost and in cylinder pressure. We will feature in the future stretch type bolt kits, that will cope better with pressure/material expansion under severe driving conditions.

Note

The use of large size thread and high tensile strength bolts can lead to cylinder deformation and also cracks. We recommend to bore the cylinder under torque, with a dummy cylinder head installed.

The M12x1.75 thread needs to be machined and tap. We recommend to drill also the cylinder head through holes, due to the factory manufacturing process, there might be some inconsistency that might interfere with 12mm bolt/studs.

These bolts are not stretch type bolts, thus we highly recommend checking your block for thread quality and cylinder-bore with a ultra-sonic device to ensure having a good block that will keep you happy with the higher tension of the bolts.
