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.

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....
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 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.
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
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.
All of the products fit as direct replacements for the OEM products they replaced.
Gordon - 04/29/2021I 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.
I had rusted old bolts and leaf springs, these were great replacements. No issues look great work well and fast shipping.
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.
Great product, great service, can't say enough good things about trailer...
William - 01/21/2019Never had an issue with these folks. Product is good quality and comes in a timely manner. Easy ordering, too.
quick shipping good to buy from.
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
Fits the bill. Installed on a tandem utility trailer wit 3500 lb axles and double eye springs.
These were exactly what I needed to complete the installation of new leaf springs on my trailer
I fixed my 5 wheel today with all the parts I got from you changed,all the equlizers and the shackles on both sides,my fifth wheel camper was blowing tires left and right.the shackles were almost wore all the way through the the end of the shackle.the tires were out of line with a straight line by two inches,when I got the new parts on the tires were right in line.thanks for the great prices and your web sight was easy to use and fast shipping I will be ordering from you again.thanks ron
Ron A - 07/20/2016The bolts are top quality - exactly what I was looking for. Speedy delivery - even considering the border crossing into Canada.
Kit was packaged excellent. It lifted my trailer enough to help my clearance issue. The directions are good and products are well made. Very happy!
Only 4 stars since only been a year. The whole package was an easy install. Completely satisfied!
One year later and still working great
I couldn't get these bolts locally. They were of good quality and priced right.
I needed a U-Bolt Kit and Shackle Straps for my trailer. Etrailer.com had exactly what I needed. Roger gave me professional advice and friendly service in placing my order. The parts were shipped lightning-fast, and the quality was outstanding. Highest recommendations for etrailer.com!
Working great just what I needed.
Correct parts and worked as they should. Replaced springs and hardware on one side of trailer the day i recieved parts.
