Most Popular Suspension Bolts for 2006 Toyota 4Runner

My manufactured trailer did not have this type with a grease fitting. They wore out the bushing in no time. I really like the design and ability to lubricate the bushing.

I bought a set of these bolts to replace the hardware in the triple axle suspension of my toyhauler. I had read about the benefits of a wet bolt kit, and after finding two broken shackle plates on my camper, decided I too needed to be able to properly lubricate the moving parts. These were a perfect fit and replacement for my original bolts. At the time I installed them I hadn't read about orienting the hole in the bolt to the 3 or 9 o'clock to ease pumping grease through them. I put them in at whatever orientation they were in my hand, but had no problem pushing 3 - 4 pumps of chassis grease through the zerk. I was able to observe grease flow out of the spring eyes around every bolt, and all of the zerk fittings stayed firmly in place when I wrestled the grease gun nozzle on and off. There were a few bad reviews about these press on fittings falling out, but I didn't see any evidence of that. I am very pleased with this purchase, and enjoy the peace of mind that comes with knowing I can properly service my suspension and hopefully extend the life of all the components in the system.

New bolts made replacement of springs easy

Good quality shackle bolts. Would buy again!

Your shipping time went wrong, but Kelsey’s way of handling My order with problems, made my respect level go up. Also, on your website, you have a picture of equalizers that look American made, with your name on it. What I received was stamped China and looks cheap…..

These are the exact bolts used by the manufacturer of my trailer. I had a spring break after 10yrs use, so am replacing the springs and all the bolts at the same time, thank you to etrailer for the springs (ordered earlier) and now the bolts/nuts, all arrived quickly and accurately, you are my first choice for all trailer parts for my 7 trailers, thank you and keep up the good work!

When I asked questions about my order they answered back quickly. Everything fit like it should. Yes time will tell if the springs are good.

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.
