Upgrade your single-axle trailer's suspension with this heavy-duty hardware kit. 1/2" Thick, sturdy steel shackle straps replace the standard shackle straps on your trailer's double-eye leaf spring suspension for heavy-duty applications.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.
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!
Bart M - 05/17/2021Great product to remove the squeak on my rv travel trailer. I did have to slightly tweak the pre-set bolts on the shackle so the other side would fit over the bolt ends. I did struggle with setting the eye spring bolts into the existing frame mount. You may have to drill out the frame eyes so your bolts will seat flush into the frame mount. Great job Dexter on this kit!
etrailer has delivered again. Great company for your RV parts. Looking forward to next trip to see how Suspension Upgrade works, but took trailer for short 10 mile test pull, & so far I think I'm going to be impressed.
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.
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.
This has been an awsome upgrade from the standard plastic bushing and quarter inch thick shackles. Installed super easy. As most may know, the original plastic bushings that come standard are essentially worthless. And the thin standard shackles cut through the bolts and elongate the holes in a very short time. With this kit, the bronze bushings, along with the wet bolts will extend the life of these components almost indefinitely. All this, together with the half inch thick shackles, insure the shackles remain perfectly vertical with no tendency to lean out of plumb due to the additional contact surface with the bolts. I don't anticipate ever having to change them. Just pump a little grease in the zerk fittings every 5,000 miles or so, as suggested in the instructions. If I had any criticism at all, it would be that these come with straight zerk fittings that make it difficult to get a grease gun on (even with the hose type) because of tight clearance with the tires. Easy fix though, I just replaced the originals to angled zerks. I've already put about 8,000 miles on these in the first year. One of the most cost effective upgrades I've ever done.
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!
This is A very good product we traded campers and our new camper has the up graded shackles from the factory very satisfied with them
I just received this product so it's not installed yet. So my high rating is based on: 1- It is exactly as pictured and described. 2- Quick delivery from time of order placement. 3- Price. If there is a better price out there I didn't find it. I have ordered various items from etrailer before and have only been disappointed once. But that was on the manufacturer of the product, not etrailer. I was able to return the item and was credited in a reasonable amount of time. I will continue to use etrailer.
Kenrod - 02/26/2018These 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.
It was what I ordered. Description of the item was excellently stated. Item was delivered in a timely fashion. I had to send an email to request for the UPS tracking number. Other than that, I have no complaints and the product is what I wanted. Thank you for a great product, delivered in a quick time frame. Thicker shackles with the wet bolts are definitely better than the stock ones.
Leonard - 02/24/2018Great service even if there was a glitch in the original shipment. Have not had a chance to do the installation but it appears that there will be not problems. This kit should be much better than the original parts.
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!
Beefy replacement for stock linkages. Direct replacement, no issues with installation. Recommended
These are great. I did not do the install myself. Like the abilty of being able to grease them and keep the wear down. Fit perfectly and the plastic ones even only had 1,000 miles on them showed lots of wear. This really are a must for your suspension. Factory ones are the bear minimum at least on my trailer.
mike - 11/25/2017Shackles 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!
Gary - 10/01/2019These 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.
Looks and works well
A must for any spring axle trailer!
Item as described, met my needs when replacing stock RV suspension.
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!
At no fault of etrailers, I received this with a key missing piece, After a phone call, the missing shackle link was sent directly from the manufacture.
