Nice kit, everything fit like it should, easy to install, with the wear this trailer had, obviously had to do a little tapping here and there.


service was excellent as usual delivered earlier than promised. I was however disappointed in what I received. The ubolts were not as promised. they only had 2 inches of thread I needed about 21/2. This was a surprise as I was told they would have 4 inches.This meant a trip to an automotive store to get what I needed. now I have 8 ubolts that are not much good to me. How unlike etrailer.

I checked and we do not have nine sixteenth suspension bolts that will have a longer thread length.

Full disclosure: we boat in brackish water in Florida, but I always hose the trailer down afterward.
Springs work as they should and installation was straightforward. However, I’m not sure how long they’ll last. After only 5 or 6 launches/ retrievals last year, this is what they look like now. The springs and equalizer must’ve been spray-painted at the factory, not powder-coated. I believe made in China. I even soaked the bolts and links in motor oil before installing to stave-off corrosion. I just hope we don’t have a failure on the road any time soon because of this accelerated corrosion!


After all of the bad weather I was able to finish installing my new suspension system on my 1992 Lance Fifth Wheel. The task was much easier than I had anticipated. The instructional video you provide access to were a big help. Other than having to grind off a nut or two I had no difficulties (See attached photos). The 'list' that had developed on the fifth wheel is now resolved, and towing has already proven to be better.


I ended up buying something different. Very poor quality. I did email etrailer to see if they would do something and waited a couple of weeks for a response and I’m still waiting. After the second nut and bolt combo stripped I pulled everything from this kit off and put it where it belonged. In the garbage. Sorry for the bad review but I tried.

I sent a note to customer service about this and they will reach out.

You buy two kits works fine for a three axle trailer real pleased with product thanks


E trailer delivered the product 2 days earlier than estimated. They were delivered in good condition, and quality products as usual.


Trailer has 13000 miles, much of it on rough highways. I realized there was looseness in the suspension and could see the shackle holes were showing some elongation. This kit restored it to good running condition. The marks on the parts indicate they are of the same manufacture as the original equipment from LCI. I am very satisfied with the results. I also changed the original equipment brake assemblies at the same time installing Axletek self adjusting brake assemblies.


I ordered some stuff and the order was acknowledged immediately. I waited a few days and it showed up. The order was correct and my card wasn't charged until the order shipped. Everything was exactly as it should be. Can't do much better than that.


I was very pleased with the expert and friendly guidance that I received when purchasing the trailer brakes and suspension components. The staff was thorough in ensuring I had the correct components for the weight and use of my trailer.


Everything as expected. Great customer service area also. Working great on trailer should of done this year's ago. Thank you and I'll be back


Very high quality replacement springs and bolts


Excellent replacement parts for worn out trailer suspension. Fitment was great. And shipped fast.


Never been so impressed with the level of service or quality of product. Absolutely not only would buy from them again, I have multiple times. And will continue to do so for any future trailer parts!!!!


Customer service was great- I called to make sure I was ordering the right part and they helped me to review my items and confirmed that it was the part I needed. Delivery was as expected and the product was perfect!


they worked well on dexter axles


Well, my suspension replacement and over/under swap went great! You guys were very helpful in ensuring I got the right parts and didn't waste money on shipping and other parts I didn't need. It tows like a dream now. I hardly even notice it behind me and I really don't have to slow down to .05 MPH for every little dip in the road.


Converted my 30 ft home built trailer to carry my 25 ft sailboat with 3 1/2 ft keel. I needed new springs to carry her weight Your parts arrived on time. So far all is going well on the upgrade. Thanks for the positive information and can do attitude of your company.


quality is on par with price. cost effective rebuild


This kit worked out perfect for my 16' 89 layton travel trailer. I have the elusive 2800 lb axles (which axle tube diameter matches 3500lb axles) which I have been told by etrailer tech support were made specially for the RV industry. I also replaced the leaf springs but had to get them elsewhere because etrailer does not stock them. The info on the 2800 lb axles I got from etrailer was invaluable in being able to locate the leaf springs I needed.


I received this product and had a manufacturing issue. After a few emails back and forth I was fully refunded. Unfortunately this stuff happens and I wanted to thank etrailer for taking care of the issue. Thank you and I look forward to continued business.


The suspension kit was just what I was expecting they are high Quality for the price I payed I would definitely get parts from etrailer again.


Ease to find the items that were needed. Fast delivery. Appreciated the additional information regarding each product, it was helpful to make a good purchase.


great customer service fast shipping best place to get all your trailer needs


Seems like a good product haven't tested it yet only thing that could be better is the way it's shipped bolts were all loose in box which could cause the threads to get mangled
