Today we're going to take a look at the 4 11/16 long wet equalizer bolt with the greased zerk fitting on one end. It comes with a castle nut and this is for double eye springs. Now this bolt will secure your equalizer to the center hanger of tandem or triple axle trailer suspension system. The greased zerk fitting here on this end will allow for easy lubrication to keep your moving parts functioning properly. The zerk fitting right here will allow you to grease the inside of the bushing. Basically you just put your grease gun on there, pump the grease into the zerk fitting.
It will go on the inside, come out this hole and lubricate the inside of the bushing. It does also come with this castle nut which is used to secure the bolt in place and then once you install this, they do require you to use a cotter pin to slide through there to hold everything into place. Now the cotter pin is not included. We do sell that separately on our website. The specs on this, the bolt is a grade 2 bolt. The overall length, which will be measured from the very bottom of the head to the very end, is going to be right at 4 11/16th long.
The bolt size is a 7/8" diameter bolt, 9 threads per inch. Then the nut size that installs right here on the end, that is a 1 5/16th size. I happen to have an example of a 1 5/16th socket and you can see it fits exactly on there to tighten it down. That should do it for the review on the 4 11/16th long wet equalizer bolt with the greased zerk fitting and the castle nut for double eye springs.

Works great! Easy to grease, and grease still flows fine into the shackle!
