Keeping your trailer suspension smooth and noise-free is a breeze with the built-in grease zerk. This feature ensures that all moving parts are easily lubricated, enhancing the lifespan and performance of your suspension system. It's an essential upgrade from standard, dry bolts, particularly for those hauling heavier loads frequently.
The inclusion of a castle nut ensures that the bolt is securely fastened, preventing loosening over time. This feature is crucial for maintaining the stability of your trailer suspension, particularly in harsh terrain or when carrying substantial loads. Install it correctly, add your cotter pin, and enjoy peace of mind on every journey.
Enjoy the assurance of a precise fit with the 4-11/16 inch length and 7/8 inch diameter of these bolts, designed to perfectly match your tandem- or triple-axle trailer suspension needs.

Users have experienced a significant reduction in wear, even after extensive use. Perfect for those who regularly tackle long hauls with heavy loads, this robust construction minimizes downtime.

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.
great fit
This product here you looking at I couldn't found it at any trailer site or store because of the square end except at etrailer love you guys was cheap fast shipping no hammer needed fits just right..
Grease fittings are press fit in not threaded grease fitting pulled out on second time greasing it wish it said this in the description I wouldn’t have bought it… junk
worked great. perfect replacement for my load trail 7 k tandem axel. I paired this up with a new 2 inch bracket and bushings.
Fits perfectly with the new 11" equalizers I replaced on my triple axle trailer. I've heard complaints they don't come with the cotter pin. They were $.37 a piece people. Just go buy some. I always use etrailer for my trailer parts. Everything is good quality, fits perfectly, and arrives on time.
Replacement
Easy to find on website with about of options as well as fast shipping and great pricing
Looks just like original.
Fast shipping great selection
I love these things. I pull heavy loads day in and day out. 3-500 miles a day everyday. I was having to replace all the undercarriage bolts and shackles once a year due to wearing the bolts in half and making the shackle bolt holes oblong shaped. There was so much slop it worried me to be on the highway doing higher speeds. I did my one your inspection and there was very little wear. And that made me happy. Last time I had to stay up until 4am with one of my workers and cut everything out from under the trailer. Then re-weld and and install everything back. It's a serious problem when you don't have time to do it. This product will help save on downtime, labor and money.
The postal service mishandled my order and I would like to thank etrailer for sending me another package for free. I received them today. I've always had fair pricing and quality parts from them.
Would be 5 stars but cotter pin should come with item
Good product has worked great on my dump trailer, fast shipping
This is a must have for anyone with a heavy load. The life of my suspension has been extended, thanks etrailer!
We have had great experience with eTrailer, These parts came in as described.
Was just as described and worked great with the equalizers I ordered
Great product and fast shipping!
Greasable bolts to go with new equalizer bars. Great prices , fast shipping.
This looks to be a quality part. Including a 5/32" x 1 3/4" cotter pin, while not a big issue, would be nice.
Allowed me to complete repairs to stock trailer. Wish I had found etrailer earlier for the components that were sourced locally. Will use etrailer next time as my first choice source.
All products received were correct, quality of parts exceeded my expectations. Etrailer employees go above and beyond for the customer, and their knowledge of products is outstanding! Will definitely return as a customer.
Everything is excellent, the package arrived way faster than I thought. The only problem is I forgot to add 2 bolts to my list. I will definitely be ordering from etrailer from now on.
Good quality springs and bolts, revived the suspension on the trailer. Quck turn around and delivery.
No hole was drilled in the king pin. Shipping was fast
