ARP high-strength bolts and fasteners for tuned engines, BMW B58 head bolts

ARP manufactures the world’s most renowned high-strength fasteners such as cylinder head bolts, flywheel bolts, crankshaft bolts and many other critical components.

In tuned engines, the forces acting on the bolts are extremely high, and many gasket leaks, cracks, and failures are actually caused by bolts that stretch and cannot handle the load. ARP has become a household name in the industry, not only for producing aftermarket bolt kits for a wide range of applications, but also for supplying fasteners to performance parts manufacturers as part of their product packages.
