Today we're going to take a look at the 3-inch-long shackle bolt with the lock nut for double-eyed springs. This bolt will secure leaf springs to your front or rear hangar of your trailer's suspension system. Does include this lock nut to secure the bolt into place. Now the bolt itself is a grade-5 bolt. The overall length on this bolt if we measure it from the bottom of the head to the very end and see is going to be right at 3 inches. The bolt size is a 9/16th diameter by 18 threads per inch. The bolt head size is 13/16ths of an inch.
I got example here's a socket. You can see it will fit the head perfectly and then the lock nut which goes on the end right, the size on that is 7/8ths of an inch. You can see it fit rights into a 7/8ths inch socket but that should do it for the review on the 3-inch-long shackle bolt with the lock nut for the double-eyed springs.

9/16" Diameter spring-retainer bolt is used to mount double-eye spring inside front or rear hanger. Includes locknut.I am very pleased with the quality and obvious necessary strength of these shackle bolts and the locknuts. I do wish the free shipping incentive was "Orders Over $50" vs $99 as well as a quicker turnaround for delivery. I ended up having my local trailer guy providing the 3 shackle bolts I needed but I will use these to replace the other 3 eventually and have one to spare. Overall though, I am pleased with this order and appreciate etrailer.com having the selection of components I needed.
Other than the parts taking a month to process, once they were gathered and packaged, they were delivered within 2 days! I replaced both sides with new 3-leaf double eye springs, 4 shackle straps, 6 shackle bolts, 2 Dexter U-bolt plates, and 2 U-bolts. They were really easy to replace and I did it quickly. Looks great, gonna take her out soon.
I replaced leaf springs on my trailer , springs , unbolts and leaf eye bolts were perfect fit and the job when easy the hard part was getting the old springs off. I know now to keep them siliconed up from now on for future problems.
I replaced my leaf springs, drums, brakes and added the Dexter E-Z Suspension kit to my Keystone Cougar Fifth Wheel trailer last year. This was my first time working with etrailer and I can’t say enough about how well it all went from the ordering to the install. Tammie P did a amazing job with knowing what parts would work best on my trailer. Tammie also gave me updates on my deliveries that I appreciated. I had a trip planned short after I received my parts. So having someone at their end checking on arrival dates helped. In the future I will definitely use etrailer for all my trailer needs. Thanks again for all the help! Great Team....
I bought springs, shackle bolts, and u-bolts and plates. Everything was great and fit perfectly. Only issue were the u bolts which were not galvanized. However, at a local trailer store, I bought galvanized U bolts for $4.50 each. For the DYIers, taking the old ones off took more than 4 hours for each side. My existing shackle bolts were so heavily rusted that I had to cut three off with a hack saw. Difficulty was confined space to operate hack saw with boat still on trailer. However, reassembling the new springs was less than 45 minutes each side. Must have tools are large diameter 3/4-13/16-7/8 deep sockets (6 point), 2 2 foot long breaker bars and a can of PB blaster. For safety: Good quality jack stands, minimum of 3--don't rely on the front trailer jack as it may roll. By the way, I did these myself and I am 64 years old.
I bought a used Jon Boat trailer and first time out the shackle bolt gave out. Perfect fit for my application and I really like the way the nut was made so that it locked on the bolt. I used these with the Never Fail Bushings. I had to drill out the shackle to accommodate this beefy bolts but that wasnt a big deal. I ended up doing both sides that had standard bolts instead of wet bolts. Not sure why only 2 were regular 3/8 inch bolts.
I replaced my leaf springs and shackles on my trailer and these bolts fit perfect. They come with lock nuts and they definately won't be coming loose. If I had to do it again I would have bought an impact wrench to make the job go quicker.
Grade of bolts are good for a leaf spring bracket.
Ronald J - 06/24/2021Installed all items and my boat trailer is like new. I was very impressed with your fast service and selection. I was able to find everything I needed in one place.
I was surprised how fast my last order arrived I needed the bolts to finish my leaf spring job , finished it and very happy with the exact replacement parts.
These shipped with some leaf springs. Box was received open(nothing missing. I suggest you consider doubling up the cardboard around the ends of the springs and taping all the edges completly
Great product, great service, can't say enough good things about trailer...
William - 01/21/2019All of the products fit as direct replacements for the OEM products they replaced.
Gordon - 04/29/2021If you’re rebuilding your suspension this is the way to go. Very pleased with my purchase.
The bolts are top quality - exactly what I was looking for. Speedy delivery - even considering the border crossing into Canada.
I had rusted old bolts and leaf springs, these were great replacements. No issues look great work well and fast shipping.
It was a job to change it out but it has worke like new. Great job.
I purchased the 3000# axle springs and all mounting hardware to replace the old ones on my 1963 travel trailer. My trailer no longer leans to the left and goes down the road better than new. I should have done it many year ago. I received my package on time and installation was easy and fit perfect. Thanks Bridget
Much better than I can find locally

Ron A - 07/20/2016100% satisfied as always. Great products and award winning customer service!
This was an amazing interaction: the woman who helped me couldn’t have been nicer and got me to the correct parts, they arrived within 36 hrs., and everything fit! Wow! Just about perfect. Thanks.
Great products. I have yet to install them. I ran into problems as the old shackle and spring perch bolts and nuts were tac-welded together. I've got to find a grinder.
Fits the bill. Installed on a tandem utility trailer wit 3500 lb axles and double eye springs.
