Great upgrade for my Dexter axle. My old hangers were toast and of much lesser quality. I have about 40,000 miles on the old set.



by:

My small travel trailer had an awful suspension system creak. It was embarassing to drive through a campground. Not only that, that noise must have indicated things were experiencing unusual wear. Since the suspension upgrade, the creak is gone. I had my upgrade installed by a mechanic, but someone reasonably handy could likely do the job themselves.

Henry

After a year and a number of outings with the trailer, the suspension is still creak- free. Very happy to have made the upgrade.

@Henry We're glad your Dexter # K71-358-00 Suspension Upgrade Kit is working well for you!


by:

One of the brackets in the kit was the wrong size. Not etrailers fault but they took care of it right away. Brackets are well made. I did strip one of the nuts so be careful not to over-torque them.



by:

The package was majorly damaged, but thankfully, nothing inside was damaged. I'm unable to upload the picture, but I don't know why. I tried 4 different formats.
the other problem is the shackles. The shackle straps didn't fit together, so I had to pry them apart to get them lined up.
I was going to give a 3 star review, but since I can't even upload pictures of the destroyed box, 2 stars it is.

I apologize for the issues uploading a photo. If you send the photo to me, I can upload it for you.



by:

These are certainly an upgrade over the factory shackles that came with my Keystone. The holes on the factory shackle straps were ovalized by the 9/16" bolts, so clearly undersized and/or overloaded. These upgraded shackles appear up to the task, and the ability to grease with the zerk fittings should ensure long term durability. It's handy to have a shop vise to widen or shrink the large shackle with the two bolts already pressed in, as they came slightly bowed in, and I had to stretch them out a bit for the opposing strap to slide over both holes. No special tools were required to insert the bronze bushings into the spring, I simply used the included bronze bushings as a punching tool along with a brass hammer to hammer out the factory nylon bushings inside the leafs.



by:

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.



by:

The Morryde tandem kit and the Genuine Dexter single axle kit appear to be quality material, the shackle straps are massive compared to the 1/8” original mild steel straps, and so far have been easy to install. I did this upgrade on a trailer with a GVWR of only 8500# and 3500#, respectively, but if you have a heavier trailer I think you would be a fool to not buy these kits and have the reassurance that your suspension is not the weakest point on your trailer. You only need basic tools to do it, but if you’re short on time, buy the kit and have a shop install it for you. I also bought the Lippert Road armor and have a Shocker equalizer hitch and now you can’t tell there’s a trailer hooked up to me. If your back hurts like mine did after hours of towing because your wife is stuck on her phone or napping, spend the money on these upgrades.



by:

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.



by:

Very happy with the quality/ thickness of the material.
Installation was easier than I expected.
Over all this is a good upgrade investment.



by:

Everything was great! Looks like it will do the job.



by:

Great upgrade from what it was these units are pretty well over loaded soon as you take it off the lot 4400 pound spring assemblys and camper is 8600 empty these 5 leaf units should help



by:

My original hangers where bent some how. So i decided to get this. When i was swapping out the bushings ona leaf spring that was only a year old, the plastic bushings where destroyed after only one year. Im very happy with the metal bushings that come with this hangers and the fact i can grease them regularly. I very happy with this product.



by:

My rig was going on 5 years old. I knew it was time to upgrade before breaking down beside the road.

These are extremely heavy duty parts.

I am sorry that your items arrived like that. Was anything damaged or lost?



by:

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.

I am still very satisfied with all the products you mentioned.Thanks for checking!



by:

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!

Working great a year later



by:

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!

Tony

My trailer is still amazingly quiet! I have to add grease to the grease zerk about once a month, but am still extremely pleased with this product.



by:

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.

great



by:

We had this awful squeak. I was so loud and embarassing. This took care of the problem. No more squeak.



by:

Peace of Mind. That is what I think of after upgrading the suspension on the trailer. From the brass bushings to the thicker shackles having a more sturdy and dependable suspension on the trailer gives me peace of mind when traveling around. My family did a big trip cross country last summer and I never had to worry about the suspension because I had upgraded to a more heavy duty set up. The dexter components I used are absolutely perfect with the road armor suspension equalizer that I installed. I definitely recommend upgrading the suspension from what comes standard on most travel trailers.



by:

Easy to install and working great.



by:

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

11/25/2017

We have had these for a year now and they work as expected. So nice to be able to grease these.



by:

Those wet bolt are the only way to go on a leaf trailer. Easy to install, maintain, and will outlast the springs if greased regularly



by:

Very good product

  • Fitment of Replacement Equalizer for 2019 Coachman Freedom Express 292bhds
    The Equa-Flex Cushioned Equalizer # LC314336 will be a great replacement for your factory equalizer. I recommend 2x # K71-358-00 for a wet bolt kit so that you can easily grease your hardware. You may also need a new bolt to fasten the equalizer to your trailer. For that you can use # 34007-187-00 and # 006-092-01.

  • Can You Use Industrial Strength Red Grease In The Dexter HD Suspension Kit # K71-358-00?
    Yes, you can use a Lithium Complex grease like Lucas Oil's Red and Tacky or Lubrimatic's LMX Industrial Strength Red Grease, # L11390 in these shackles. These Lithium Complex grease products resist water and stay in place, which means they work well on external parts that are exposed to the weather. Lithium Complex grease works well with trailers that are heavily loaded as well as industrial or agricultural trailers that get a lot of use. If your trailer is not used for industrial or...

  • Will Dexter Heavy Duty Shackle Upgrade Kit Fit 2013 Jayco 184BH Camper
    The Dexter Heavy Duty Suspension Upgrade Kit for Single Axle Trailers # K71-358-00 is a great option to replace your current hardware but you do need to make sure that the 3-1/8" center of bolt hole to center of bolt hole measurement matches what you currently have. If there is a slight difference you will still be okay but if it is significant then you'll need to choose different shackle straps which you can filter through on the linked page.

  • Piecing Together an E-Z Flex Equalizer System with 3 Inch Shackle Straps
    Dexter Heavy Duty Suspension Upgrade Kit # K71-358-00 is exactly what you need though on a tandem axle you would need 2 sets. E-Z Flex System # K71-652-00 does not use wet bolts to hang the equalizer part. It has grease fittings on top for that so you can just use a regular bolt. So you would use # K71-654-00 for the equalizers by themselves, 2 of kit # K71-358-00, and either reuse the hanger bolts you have or use 2 of # TRFA73Z916DLNZ or a similar bolt.

    We can get you the right shackle kit for your single axle trailer with a Dexter 3,500 lb axle, and you can choose from either a standard kit or an upgrade kit. Either will work, though the Upgrade Kit is going to be the best option due to the fact it includes thicker 1/2" shackles, wet bolts with grease zerks to make lubrication super simple, along with bronze bushings for the longest lifespan.

    The only 3-1/8" shackle kit we carry from Dexter is the # K71-358-00 which is for a single axle trailer. If you are in need of a complete kit for a tandem axle trailer, we recommend the MORryde Suspension Upgrade Kit # MR76ZR. This will come with very similar 3-1/8" HD shackles, bronze bushings and wet bolts just like the Dexter kit. The equalizers are sold separately, and we have many different sizes available depending on what you are needing. We just want to make sure a replacement...

  • Why Dont Trailer Hangers Come with Bushings.
    The # 30-20 hanger is a unique hanger as it comes with it's own bushing that has an inner diameter of 9/16 inches and installs in a different orientation than most. Like Victoria said, the reason most standard style hangers do not come with bushings is because the bushings are on the spring side of the equation. While what you said is true about wear with dissimilar materials, the reality is that hangers don't wear out at a fast enough rate to warrant a different approach. We rarely hear...

  • Purpose of Replacement Bronze Bushings in Dexter Heavy Duty Suspension Upgrade Kit
    The bronze bushings in the Dexter Axle Heavy Duty Suspension Upgrade Kit # K71-358-00 are replacements for the bushings in the eyes of the double eye springs. Since this kit is for a single axle trailer with double eye springs, there will be 4 eyes in the suspension set-up, and the 4 bushings are for those 4 eyes.

We have them in a 23-1/8" # e59SR, 25-1/8" # e68SR or 27" # e97SR length. You will want to select the spring length slightly larger than your mounting bolt pattern.

    There is a way for you to flip the axles of the Dexter Trailer Axle with Idler Hubs # 20545I-EZ-72-15 you asked about, though the over/under kit you mentioned won't work because this axle is too small in diameter. So while there isn't a similar kit for the 1-3/4" axle tube of the Dexter axle, you can put together the pieces needed, which are the following: - U-Bolt Kit for Mounting 2,000-lb, Round Trailer Axles # APUBR-10 - Spring Seat for Typical 2,000-lb, Round Trailer Axles with 1-3/4"...

  • How Often to Grease Dexter Heavy Duty Suspension Upgrade Kit # K71-358-00
    If the trailer wasn't used very often once a year would be adequate for greasing the Dexter Heavy Duty Suspension Upgrade Kit # K71-358-00. Beyond that it really depends on the how often it's used. For most people twice a year would be adequate. But if the trailer is out every day probably once a month would be smart.

  • Why Does the Dexter Heavy Duty Suspension Kit for Single Axle Trailers Only Have 4 Bronze Bushings
    The Dexter Heavy Duty Suspension Upgrade Kit for Single Axle Trailers # K71-358-00 comes with 4 bronze bushings since that is how many you need to replace them for the leaf springs. That being said, if you wish to use 2 more for the remaining wet bolts on the hanger you can always buy the # D014-077-00 separately.

  • 2-3/4 Inch Long Shackle Straps and Wet Suspension Bolts for Trailer Suspension
    The eye center to center measurement on the shackles included with Dexter Heavy Duty Suspension Kit # K71-358-00 are 3-1/4 inches apart. You would need to piece together a similar kit since there are no options that already have 2-3/4 inch shackle straps. For shackle straps you can use # TRSL275, sold as singles. And for a wet bolt with nut, also sold as singles, you can use # 126B2. The shackle straps aren't the thick kind like in kit # K71-358-00 though.

    Having a 1 inch difference in the length of the shackle straps would be a pretty drastic change to the amount of articulation you get out of your suspension, so going with that kit wouldn't be advisable. We don't have a kit that uses longer heavy duty shackles, so you'd need to assemble the parts separately. • You'd need two of part # K71-358-00 • Two # TREQ104 equalizers • Two of # TRFA73Z916DLNZ shoulder bolts with nuts This will provide you the same kit, but with longer shackle straps....

    The Dexter Heavy Duty Suspension Upgrade Kit part # K71-358-00 would allow you to upgrade to wet bolts and bronze bushings on 1-3/4" wide double eye leaf springs. The wet bolts and bronze bushing will last much longer and preform better than the standard bolts and nylon bushing currently in place. The kit does come with extra wet bolts if you are only doing the shackle side. If you have a tandem axle trailer you would need two kits.

  • Should Wet Bolts be Torqued Tighter Than Instructions
    When adding wet bolts like what come with the Dexter Heavy Duty Suspension Upgrade Kit for Single Axle Trailers - Double Eye Springs # K71-358-00 you should always follow what the manufacturer's instructions are. You are correct that over-tightening the bolts can bind your suspension, which you'll obviously want to avoid.
