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).
In addition to utilizing a rod bolt with sufficient strength to withstand the tremendous cyclical strains placed upon it, it is absolutely imperative that the bolts be properly tightened. The preferred method of monitoring the correct amount of tension is through use of a stretch gauge. This is far more accurate than using a torque wrench. Moreover, through subsequently checking the rod bolts length at tear downs, it is possible to determine if it has been stressed beyond safe limits and must be replaced.
For the most severe applications, in conjunction with aftermarket I-beam rods, ARP has developed the "Pro" Series bolts. These ultra heavy-duty rod bolts are made from a special material designed ARP2000. It has approximately 200% the fatigue life of 8740 chrome moly steel and has a tensile strength of 220,000 psi, and is capable of more than 12,000 lbs clamping force.

Cool, modern look
Color: Army Green, Size: Large
I bought this for my husband and looks great! The material is a little clingy, so I would get a one size up for a better fit. He has received numerous compliments. It fit him well and I washed it but played it flat to dry with no shrinkage problems. I highly recommend it. We ordered another one in a different color.

Too big
Color: Pink, Size: Medium
Seems like good quality, the sizes run big, I normally wear medium in most clothes, but the small is still too big for me

low-maintenance shirt that fits perfectly
Color: Black, Size: 3X-Large
This COOFANDY Casual Button Down is a fantastic addition to a summer wardrobe, offering both great fit and high quality. The material is impressively wrinkle-free, which keeps it looking sharp and crisp even after a full day of wear. It is specifically designed to be worn untucked, and the length is just right—offering a modern, relaxed silhouette that doesn't look sloppy. The fabric feels durable yet breathable, making it comfortable for both casual outings and slightly dressier occasions. If you’re looking for a low-maintenance shirt that fits perfectly right out of the wash, this is an excellent choice.

My husband loves these shirts
Color: Dark Blue, Size: Large
My husband just loves these shirts. He has one in every color, I think. Great quality, good price, breathable, true to color, and super comfy. Nice enough to wear to a nice dinner but can be dressed down w a pair of shorts and flip flops. By far the best find I have found!
