ARP Duramax Diesel Connecting Rod Bolts

ARP manufactures the highest quality American made Connecting Rod Bolts for the 6.6L Duramax diesel engines. Because factory connecting rods or high performance aftermarket connecting rods are used when its time for a rebuild or a power increase you need the best connecting rod bolts available.

Connecting Rod Bolts are unquestionably the most important fasteners in any engine. These bolts hold the key to the entire rotating assembly. A broken bolt will lead to a 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 of the crankshaft.  When the crankshaft  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 the proper fasteners that are able to exert a clamping force greater than the load imposed upon the joint..

The ARP rod bolts for the Ford Powerstroke are made from a premium grade ARP2000 alloy steel. This material is heat-treated to provide a tensile strength in the 220,000 psi range. Cycle testing shows ARP High Performance rod bolts to be nearly five times more reliable than stock bolts. These ultra heavy-duty rod bolts are made from a special material designated ARP2000. It has approximately 200% the fatigue life of 8740 chrome moly steel and has a tensile strength of about 220,000 psi, and is capable of more than 12,000 lbs. clamping force. ARP also provides another big advantage being the shank design, with ARP’s exclusive (and patented) Wave-Loc technology providing substantial benefits.
