Most Popular 3-1/2 Inch Long for 2002 Chevrolet Silverado

I'm replacing a broken spring, this is one of the parts required to get the job done right. A perfect replacement for our trailer. Thanks

It's a bolt. Matches the one that stripped the threads coming off.

This is an excellent product, but I gave it four stars because it was nearly impossible to install with ordinary tools. It was necessary to force the serrated portion into the center hanger and since I did not have access to power to run a compressor and force it into the hole using excess torque via an air wrench, I had to use a hammer to drive the serrated end into the hanger. I found an install video from etrailer that showed how the installation was to be done, but I could not accomplish it that way. Besides the amount of torque needed would probably have twisted the bolt off at the grease hole. As it was, I drove the part in with a 3# hammer after destroying ordinary white wood blocks of wood. I removed the grease zerk and used another piece of flat iron to protect the zerk's threads. I was able to bottom the head against the hanger by tightening the nut as much as I could by hand and then hitting the head with the hammer a few times, tighten again, etc., until it was completely in place. This method was used on both sides of the trailer. To torque these into position with an ordinary wrench would have exceeded 1000 lbft of torque which I am not sure that these bolts would take without damaging them more than the hammering did. To be fair, the information suggested that the hangers be replaced, but that was because many times the hangers are damaged if the other parts wore out. But it is fairly clear that the holes in the hangers are not pre-formed with matching serrations so I doubt that it would have changed the issue. In short, I don't believe that the serrated portion is necessary. And if it is, then a keying method would be more appropriate, such as a square hole.

Other than cotter pin is way too small and had to add a couple washers so castle nut reached keeper hole a great product at a good price.
