It is for good reason that virtually every top professional engine builder relies on ARP Pro Series head studs for their all-out competition powerplants. Simply stated, there's not a better stud setup on the market today.

As the crankshaft flexes and twists, the balancer absorbs incredible amounts of kinetic energy. To ensure that the balancer is locked in place, ARP has developed these ultra-strong 200,000 psi bolts that let you exert maximum clamping force. Special features include 1/4' thick, wide area washer and an extra tall 12-point head that accepts a deep socket and eliminates the worry of stripping the head.

ARP offers a special version of its rugged 200,000 psi rated balancer bolt that can accept a standard 1/2" drive ratchet or breaker bar to facilitate rotating the crank assembly.

Unquestionably the most important fasteners in any engine are the connecting rod bolts, as they hold the key to the entire rotating assembly. A broken bolt will lead to catastrophic engine failure. As you can imagine, the most critical joint is where the connecting rod halves mate. The rod bolts must support the primary tension loads caused by each rotation (or cycle) of the crankshaft. When the crank rotates, the big end of the connecting rod essentially becomes oval-shaped and the rod bolts bend. As the crankshaft continues to rotate, the rod becomes round again. With alternating tension loads and cyclic bending of the bolts, it is very important to install fasteners that are able to exert a clamping force greater than the load imposed upon the joint (tension).
