Fit up perfectly. Split the old nuts using a right angle grinder with a cutting wheel. Heated the spring enough to soften the plastic bushing and allow the bolt to be pounded out with a hammer. I used an 11/16 drill bit to remove rust and debris from spring end and used a c-clamp to press in the new bronze bushing. Everything else went together like the instructions said. Attached a before and after photo.

Working great

They wear out just like the less expensive types. The hype for thier warranty is just that, Hype. When contacted about excessive wear with them, I was told that they are "wear Parts" What? I'll purchase the less expensive types in the future and just replace them as needed.



by:

These things are awesome and so is the customer service from the etrailer team.
The box came damaged and missing 1 small piece but a quick call to etrailer and they are sending the missing piece ASAP. Dexter just needs a better box for these heavy items.



by:

The product looks very good and very heavy duty. I’m looking forward to putting it on in a couple of weeks. I did this to my last RV which was a triple axle and it made a world of difference as far as noise was concerned from the suspension etc. Once or twice a year I’ll be Grease the Zerk fittings no noise at all.



by:

I installed RoadMaster slipper spring with shocks in November 2019 and I love it works great was an easy install should be a factory option. Install on my 2014 Heartland Big County 5th wheel no more bounce



by:

The heavy duty suspension kit was great. My only disappointment was that one equalizer didn’t have the grease zirk installed on it.
The company immediately sent me a new equalizer. I am very happy with their service and support.



by:

Fit perfectly. The Dexter equalizer has longer than the stock one but wasn’t and issue. In fact it actually raised my cargo trailer about an inch. Love the Zerk fittings when it comes to maintenance. I only have one negative thing to say. Dexter should consider protecting the instructions a little better. Placing them in the bottom of the box with the parts on top is not a very good idea. It make for some difficult reading.



by:

I was needing suspension parts for my camper and the guys at etrailer did a great job at helping me get them. They got to me very quickly as well. Thanks!



by:

I think that was the best thing I could've done by changing out the suspension on my trailer .My trailer is a whole lot quieter to pull now.No problem yet. Good product .


Comments
The over haul of the suspension on my trailer is still doing just fine .I greased zerk fittings because I could where I couldnt with oem parts but they didnt any grease .Im still very happy with the purchase from etrailer.

2nd packaging worked much better with the extra box.
1st packaging was just the box the product came in, broke open, lost contents.
Customer service handled it well.



by:

The expensive units did not hold up on a 5 ton dump trailer for me any better than a cheap set.



by:

I wish i would have done this sooner. The factory parts didn’t accommodate easy grease, much better and set for a lifetime.



by:

Wow. Heavy duty!!! Excellent upgrade! Grease quiets transitions. Easier to Change than I thought. Remember that the bolts are pressed (hammered) in and must be driven out!



by:

Great upgrade to your trailer suspension. The equalizers on my trailer were froze and would not move, I had to heat the bolts until the plastic bushings melted, then drove the bolts out. In doing so this left a fair amount of crud inside the spring eyes, I had access to an 11/16" hand reamer so I ran it through the spring eyes, then the bushings slid in with a nice snug fit, and in doing so I did not experience distortion inside the bushings like others have mentioned. I was disappointed to find that the equalizer center pivot bolt did not come with a new nut. The kit shows enough nuts for all the bolts but the nuts only fit the wet bolts. If the kit had included the two 9/16"-18 nuts I would have given 5 stars.



by:

Very happy with the quality of the product. Have used it for over a yr now with about 5k miles on them with no complaints. I recommend this product



by:

The parts where excellent the kit is great the people where very helpful it went together very easy the grease fittings are great you don't have to take it apart to grease it


Comments
so far so good. would recommend you and your parts to everyone.

Ah.. now I can tow with confidence knowing my axles are once again equalizing and sharing the bumps as they should be. With the grease-able fittings I also know this is continue for years to come.

Feels very heavy duty, trailers well on the trips I've taken so far.
Installation was very easy, though to use the brass bushings in the springs I had to drive out the nylon bushing that came in the new springs. This was easy to do with bolt of the right size and the brass bushings -- just tap tap tap and the nylons were pushed out by the brass, all guided and kept aligned with the bolt.



by:

I have not had time to install parts yet but just joking at them I am impressed at how much more heavy duty they are compared to stock hangares



by:

The products I ordered arrived ahead of schedule and fit perfectly!

The only complaint I have is the packaging. All the components (4 leaf springs, suspension kit, and u-bolts were just thrown into an over sized box, then shipped. When it arrived, the leaf springs were sticking out the sides and there were holes big enough for the smaller boxes to fall out. Fortunately, everything was there. This is the second time I have ordered product is was packed very poorly!



by:

Easy to install. The grease able feature is very nice too. Go for it!

Still Good

etrailer- I cant say thank you enough
Finally,
someone sells a product that is done right. Within 9 months of purchasing a brand new twin 5200 lb tandem axle trailer, i lost an axle due to light flimsy spring shackles that wore through ( no way to grease them either) .I have been towing tandem trailers for the past 30 years, always having undercarriage issues (hangers and equalizers by other companies wearing through one being cheaper and thinner than the next. These are truly Heavy Duty... I can now travel down the road feeling confident that my leaf springs and axles are strong, sturdy and over engineered. etrailer was the only one i found that sold truly Heavy Duty Hardware that is truly over engineered and realistically, under priced... Thanks again etrailer



by:

Havent installed yet but this is really beefy, and I love the fact that I can grease all the joints now. These brackets are more than double the thickness of OEM.


Comments
A year later and these have been on for 10 months or so. Due to a defect in my trailer mounts, I wasnt able to use the included bushings, but it still is quiter, and beefier than OEM, at about half the price of the local autoparts store.
BradleyC W - 06/22/2018


by:

Suspension parts are working so good I have had little to no maintenance other than lubrication. The ride in the trailer was greatly improved.....a worthwhile improvement/upgrade.



by:

the FAQ section was and is a huge help. Who ever dreamed that up needs the employee of the week front row parking spot for a month.



by:

Ran these over ice and snow on I-40 from Tucumcari to Albuquerque and didn't loose anything inside. If your shackles are rusted and can't be lubed this is the fix for you. Replaced these on a 2003 Mobile Suites fifth wheel.
