The Dexter heavy duty shackle kit was simple to install. The kit included all necessary hardware and easy to understand instructions. The ability to be able to keep the bolts greased is a plus. 465493

Shackles are beefy, greased easily (I tested them before install). Much better than the factory original which had already worn after only 30,000 miles or so. Being able to lubricate is a wonderful thing! 570429

Still great. Whenever I replace my trailer, this will be one of the first tweaks I do before it is actually needed.

These should be standard on all new trailers/5th wheels! It borders on criminal that the great majority of new manufacturers use the thin metal straps that wear through to the edge in 25,000 miles or less creating a serious and possibly fatal risk of the axle breaking loose! These thicker, stronger straps with metal bushings - not plastic like on the O.E. insure durability, strenth and reliability. Plus, they can be periodically lubricated - another common sense feature missing from the O.E. units. While it took a few hours to install, it is a relatively simple and worthwhile upgrade that I would encourage others to consider. Plus, the trailer weight shakes less and flows better over rough pavement. Our unit is a 28' fifth wheel... but these are appropirate for any size TT or fifth wheel. 605230

Another great product from Etrailer by Dexter. The shear size difference between the old shackles is huge. These are definitely Heavy Duty and will last a long time over the small stock ones. I like that all the bolts have grease fittings for easy maintenance. These shackles are Amazing and I will be installing a set on my Dads trailer this year. Great product and always great Customer Service. 558681

Would have gotten 5 stars, except that they did not include bushings for the front and rear spring perches. They included the bolts, but not the bushings for the spring eyes. Still, excellent quality product. I come to etrailer.com for all my trailer needs. They ship fast and their prices are great. 907549

Purchased this product for my 2019 Nitro Z-19 bass boat trailer. These trailers are very well known to be extremely squeaky while going down the road and this product took every squeak away from the trailer. To be honest, I am amazed at how much noise reduction the wet bolts took away from the trailer. If I had to do it over again, I would make a Before & After YouTube video so you could hear for yourself at how quiet my trailer is now. Installation is a little tricky, but if you know your way around a trailer and have the correct tools, it's really not that bad. If you are looking to take the squeak away from your trailer, do not hesitate and purchase this right now! 853713

These parts arrives exactly what I expected, great condition. My error, they knew they were heavy duty, but MUCH heavier than I expected. But, they still worked, and I can promise, these won't fail anytime soon! Great product, timely shipping! 804816

This was THE addition I was looking for on our used camper we just bought. Turns out the shackle straps had NOT been serviced every 25k miles and 2 out of the 4 sets had completely sheared through, others all compromised and ready too. This was missed at time of purchase and I towed it home without knowing, NOT SAFE. I wont worry again about them AND I can now service the through bolt and provide lubricant to each pivot connection. I highly recommend! It would of been a a 5 star for be, but out of box on 2 sets I had to manually bend and align all 4 pre anchored posts that were aready installed on one strap to match the pre-drilled holes of the other to align properly. It was as if they weren't dry fit before packing and shipping. 801036

If you look at the pictures, you will see why I had to do something. This trailer is only 3 1/2 years old and has less than 3000 miles on it. I only stumbled upon this when I was looking for something else! These work great! Just do your homework and verify your dimensions. etrailer has been one of my go to sites for rv parts. Thank you so much for giving us the opportunity and pricing to help us doit yourselfers! 798892

These shackles are hands down better than any factory ones on any RV. They have Greece inserts on them. These go on easy and fit perfect on my RV. I am so glad that I crawled under my RV for this years inspection. It was easy to order them online through etrailer. They arrived fairly quickly as well. They are a great price for what you get. I bought one set just to try out. Then ended up ordering the other two sets. I have a triple axle RV. 791028

first of i'd like to thank etrailer for their excellent customer service. as far as the bushing kit goes, none of the 4 bushings in the kit fit into my axle. i broke 3 of them trying to hammer one in as per the supplied instructions. after that failure i tried pressing the other 2 in with no luck!! i went to a local hardware store that sells trailer parts and bought nylon bushings, that worked! this also is not the easiest installation to do! 790805

I received my order the other day. it was packaged well and everything was intact. I compared the new shackles to the old and there is no comparison. The new ones are much thicker and just look stronger than the oem's. The wet bolts look like they are going to be a great improvement. Price was pretty good too! 779222
