ARP high-strength bolts and fasteners for tuned engines, BMW N54 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 stressing the bolts are also extremely high, and many gasket leaks, cracks, and failures are actually caused by bolts that stretch and can’t withstand the loads applied to them. ARP has become well known in the industry not only for producing aftermarket bolt kits for many applications, but also for supplying components to performance parts manufacturers as part of their products.
