All parts were perfect fit. Quality hardware and performance.


I bought the spring kit to put on my home built trailer that I put my old heavy slide-in camper on. It more than met my expectations. There was no sway at 75mph or on the 5 mile trail back to camp.


I think these Trailer spring hangers are working out very well. Can’t wait to test it out on the road. I’m building a 7000 lbs GVWR trailer to mount a generator on.


The Trailer Hanger Kit shipped fast and was as described. Fit & finish were excellent. Great product. Made my 25 year old trailer like new again!

Heavy duty parts. Still going strong! Well made suspension parts. Shipped quickly. Perfect fit.
VettePilot - 02/03/2022


It was easy to install, and had all the parts I needed.
The trailer rolls down the road nice.
This helped me get a barn find trailer back on the road.


This worked perfectly to refurbish my 1986 Superior trailer.


We summer at a remote cabin in the Gila Nat'l Forest above Silver City NM. The last 5 miles to the cabin is extremely rough and puts a lot of wear and tear on both my truck and my trailer that we use to transport water, food, building materials and supplies to the cabin on a twice a month schedule. I have had suspension springs break, blown tires and damaged coupler. I ordered this kit to replace the entire hanger assembly because of wear and tear, cracks and loose fittings. I had to re-enforce the frame and weld up some cracks and wear points. The kit was great and worked perfect. The trailer is now like new and will serve me for years to come.


Everything I ordered was top quality and fit perfectly.I also ordered some spares. I will most definitely be back in the future! Thanks again!!


I didn’t receive all parts on original shipment. Box was partly open due to the box wasn’t big enough and that’s why it bust. After Tralee already tore part when found. I called to get replacement parts. That went well until I received what I was originally missing, and y’all sent me galvanized straps and I said to hell with it. Not going to keep waiting. I’ll paint over them. Not sure why my new order and the replacement straps couldn’t have been shipped together. But oh well I’ll wait several more days for part that was in stock in the same building probably to shopped late. Better luck next time

I will have our customer service team reach out to you.

I placed the order and realized that I had ordered the wrong parts, I called and talked to Mariah and she was very friendly and knowledgeable and figured out by my description exactly what parts I needed.
They were delivered with in a few days and everything I needed was included and fit perfect!
I am very pleased with this experience from start to finish! Great price also!! Thanks

I sold the trailer to a friend and he says it pulls great!! You guys are the best!! Still works great after a year.
Doug - 12/19/2021


Trailer hangers and all related hardware showed up in about a week in one small box, were installed professionally, and a perfect fit. Thank you.


I received my order very fast. The quality is excellent and everything that I expected. What is also impressive is that if you have questions about setting up your axle kit, etrailer has printable instructions right on their website that will make installation simple.
I have built several trailers over the years and appreciate the quality and service provided by etrailer. I highly recommend this company and their products.


I'm building a trailer for a gutter machine from scratch. And the parts that I got from e-trailer are exactly what I needed, and on top of that they got to my house 3 days earlier than they were suppose to. I know where to order again if I need some more parts in near future ;) thank you guys


I had a trailer with a suspension that needed new bushing and rocker arm. I looked on line and decided on the parts I needed. I called my order in on Sunday evening and explained I needed the parts ASAP.
The parts were sent to UPS Sunday evening. I received the parts about 2:00 Wednesday. I have already installed the parts. The suspension is back like new now.

The product I used on my trailer are doing an excellent job. No problems so far. Thanks for the follow up
William - 04/02/2018


fast shipping and great prices do it for me


Product was exactly as described. Used the info on website for location of mounts. Couldnt be happier.
Awesome customer service as well.


Gives you everything you would need for a good price


My flatbed trailer is a 1998 and the suspension and wheels were suffering from Pa's use of salt brine on the roads. The wheels had holes rusted through them! Decided it was time to repair the trailer. Got new wheels and suspension parts from E-trailer. Got my parts fast at a good price and well on my way to having a reliable trailer again. Great service and will do business again!

Year later and trailer is still working great again. PA inspection will be due in a month and everything is still in good shape

Awesome costumer service


Great parts. Easy installation. Website was easy to use and find what I was looking for. Order arrived quickly


I have ordered from Etrailer a few times now, The service is always great and fast shipping. They have the best prices around. Where I live I have 24 miles of rough dirt road so am always replacing parts on my trailers. Their products hold up to the test of my road. Always a perfect fit too!

everything is still holding up very good! Thank you guys for the excellent service!

Lots of info so you know you are getting what you need and quick ship to your door


Pics of trailer frame.


Thanks for asking. I was very pleased with your products and service. I built my trailer suspension with the measurements and technical info from your web sight. Everything bolted right up. I finished the trailer on Friday afternoon, loaded it up Friday night, and pulled it half way across the country on Saturday and Sunday.
You will be the first place I look when I need trailer parts! *

  • Trailer Suspension Hanger Kit for Two 2-3/8 Inch Axles and 25-1/4 Inch Leaf Springs
    A suspension hanger kit won't have anything to do with the space between the tires and the trailer frame but can affect the front to back space between the tires. I recommend kit # APT5. On it the center to center distance between axles is 33-1/2 inches (suggested) and since your tire size of 255/75-15 has an overall diameter of 28.6 inches then there will be plenty of space. I have included a link to our help article on double-eye spring suspension for you.

  • Axle to Frame Height Difference Between Tandem Axle Hanger Kits # APT3 and # APT5
    We don't have CAD drawings we can give out for our hanger kits but I can help give you info to help you determine what the height of your axles relative to your trailer frame would be with each kit. With the part # APT5 it will give you approximately 4-1/2 inch to 5 inch of clearance and the part # APT3 will give you approximately 3-1/2 inch to 3-3/4 inch.

  • Measuring the Distance Between Axles Using Suspension Kit # APT5
    The difference in the measurements is because the centers of the springs (and axles) are closer to one hanger than the other because of the equalizer and shackle straps. The spread between the axles is therefore a little more. If the spring eyes attached directly to the center hanger then you would be correct, the measurement would be the same. But with the equalizer and shackle straps at the center hanger and the springs attached to those, the measurement would have to be different.

  • How to Determine Axle Position when Building a Trailer
    There is an easy way to determine axle placement on a trailer. Take a look at the picture I have included. Just plug in the numbers and complete the formula to determine the axle placement. The other factor that is going to come into play is the springs that you are going to use. Once you have the measurements all figured out you can determine which springs are going to work with that set up. I have also included a link to our double-eye suspension FAQ article to the right.

  • Will Trailer Suspension Hanger Kit APT5 Fit a 2001 Fourwinds Travel Trailer
    It is possible that hanger kit # APT5 will fit your trailer. But you will need to take the measurements first like you said. When taking the measurements you will want to have the weight off of the trailer by jacking up one side. Depending on the axle capacity you could have different measurements depending on the springs used and the axle spacing and so on. If the axle measures 1-3/4 inches in diameter then using the picture I have included, the A measurement should be 24-3/4 inches,...

  • Will Suspension Hanger Kit APT5 Fit a 2003 Shadow Master Tow Hauler Trailer
    To determine if hanger kit # APT5 will fit your trailer you will need to look at the measurements in the picture I have provided and compare them to how the trailer is set up now. There are no installation instructions. The hangers get welded to the bottom of the frame where needed, the equalizers bolt to the middle hangers, and the springs attach to the front and rear hangers and equalizers via the shackle straps. So it will look like the picture. I have also linked our informational...

  • Should Loctite be Used when Install Trailer Suspension Parts
    I would not use any Loctite when installing suspension components on a trailer since the suspension components need to be able to move relatively freely. I would be afraid of getting the thread locker on bolt or something away from the threads. If you were to use a thread locker then use the blue kind. The red is way too strong. The blue will allow nuts and bolts to be removed with hand tools. Maybe I'm just paranoid but for me, I wouldn't use it.

  • Does the Equalizer of the Trailer Hanger Kit APT5 Have Movement Once Tightened Down
    I spoke with my contact at Dexter and he informed me that you will tighten down the mounting hardware as tight as you can reasonably get it, and that even though you have the hardware tight it will still allow the necessary movement for the equalizer to work as designed on this Tandem-Axle Trailer Hanger Kit, part # APT5. I attached an FAQ article on trailer suspension below for you to check out also.

  • Weight Capacity of Tandem-Axle Hanger Kit Part # APT5
    The Tandem-Axle Hanger Kit, part # APT5 is designed for use on 2000-7000 lb axles, which would be up to 14000 lbs. Keep in mind that the weight capacity of any towing system will be limited to the capacity of its lowest-rated component.

  • Will Tandem Hanger Kit part # APT5 Work With Trailer that has Tandem 3,500 lb Trailer Axles
    The tandem axle hanger kit part # APT5 that you referenced would fit and work fine with your trailer's new axles that come with springs. It would be just a matter of mounting the hangers in the correct location for the spring dimensions.

  • Recommended Clearance Between Trailer Frame and Axle
    The recommended clearance with leaf spring suspension on an unloaded trailer is between 2 - 2-1/2 inches. You should have sufficient clearance with your loaded trailer, as leaf springs only tend to deflect 1-1/2 inch when carrying a load.

  • Axle Placement Recommendations for Trailer Being Built
    The axle placement guide picture that I attached will work for nearly all trailers because when followed properly you end up with the correct amount of tongue weight for the trailer so that it does not sway. Instead of using the axle center on a tandem axle trailer you would use the center hanger for the suspension as the point D for the chart.

  • How to Determine Axle Placement for a Tandem Axle Trailer
    To determine the location for the front and rear hangers on your tandem axle trailer you will first need to make sure that you have the correct center point for your equalizer hanger. The center point of your equalizer hanger needs to be located where you will have 60 percent of the frame of the trailer in front of the center of the equalizer hanger and 40 percent behind the center of the equalizer hanger. For example, if the trailers frames length is 18 feet, then the center-line location...

    The difference in tire diameter will be an additional 2-1/2 inches going from the 225/75-15 which measure 28.4 to the 235/80-16 which measure 30.9 inches. As a general rule of thumb the minimum safe distance between front and rear tires on the same side of a tandem axle trailer is 4 inches. You would need to measure the distance between your tires currently and subtract 2-1/2 inches. If that dimension then ends up being 4 inches or greater the axle placement could be left alone.

  • Where Place Center Hanger of Tandem Axle when Building Trailer
    You bring up a great question. I attached the picture of the worksheet that you referenced as well. What works best is to first setup the center line for the center hanger so that 60 percent of the length of the trailer is in front of the center hanger and the remaining 40 percent is behind it. That usually gets people the correct placement, but from there you would want to use the worksheet to verify if that is correct.

  • Recommended Hanger Kit for 1990s Haulette Tandem Axle Trailer
    The kit that I recommend for you is the # APT5. This will be the closest hanger kit to the dimensions you provided that can work for you. You will want to follow the guide of distances I've attached for your trailer. Once you clamp them onto your trailer you may have to slightly move them to adjust for your leaf springs before welding the brackets, but this kit will work great for you.

  • How To Determine Parts Needed To Replace Suspension On Tandem Trailer
    There are a few differences between slipper springs and double-eye leaf springs. Slipper springs normally have a higher weight capacity, and fewer moving parts, but they tend to ride a little rougher than double-eye. You will need to know the length of the springs you are replacing. Over many years of use they can be stretched up to an inch. Also, it is helpful to know the height from the top-center of the spring to the center of the eye and the length from the center of the eye to the...
