Shipped fast looks good will be putting it on my trailer this weekend.



Awesome use it everyday for my work.


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.


Had what I needed to repair my trailer. Shipping was faster than expected. The kit should contain bushing for the springs as well. Also an option for the greaseable pins.


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.


Excellent experience. My order shipped and arrived extremely fast and the customer support team was kind professional and promp in answering any questions I had.


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.


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


All parts fit properly and arrived on t ime


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.


All parts were perfect fit. Quality hardware and performance.


Exactly what I needed for my trailer. Fast shipping!


Parts for perfectly. It has been a year and everything is working great and holding up well.


working good


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


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


Donna helped me a great deal and made sure I ordered just what I needed and rushed the delivery so I could attend my event to meet Tim Mattis and team up to fight veteran suicide.


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


Everything I needed was included and fit as it should.


Perfect fit. No problems.


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!

Frank L.


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


great job thank you


Pics of trailer frame.


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

  • 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.

  • What Should Hanger Distance be for Trailer Tandem Axle Suspension
    Hey Eugene, you'd want a distance of 54-1/4 inches from the front to rear hanger centers. Basically to ensure you get the right shackle angle you need the distance between the spring hanger bolt center and equalizer bolt center to be about 1/8 inch less than the spring length.

  • Suspension Hanger Locations for Dual Axle Dump Trailer
    There are some measurements missing that are important in giving you the exact positioning. I've attached a couple articles to assist with the dimensions you must calculate to get your precise 35 inch on center axles. Your center hanger will be obviously directly centered between the two axles and then your other two hangers will be spaced identically on each side. Your spring from the center of the outside hanger to spring seat location is the dimension that would be extremely helpful....

  • How To Determine Axle Spacing On Tandem Axle Dump Trailer Using 30-1/4" Leaf Springs
    I would be happy to help you figure out the axle spacing when installing your axles on your dump trailer. Since you are using a 30-1/4" double eye spring we do not have an exact axle spacing measurement as that is quite a bit longer than the springs we typically use so you will need to mock up the hangers and axles and see what works for that length spring. Your hanger spacing will likely be around 34" which would give you an axle spacing of around 39". The most important thing is that...

  • 1980s Starcraft Frames Trailer Suspension Solution
    Since that's a super unique design not supported by anything out there currently your best option might be to box the frame and then go to a more standard style of trailer suspension hanger like with the part # APT5. Basically the hangers of this would weld to the bottom of the boxed frame giving you a way to install modern trailer suspension. This kit comes with equalizers, shackles, and bolts.

  • Determining Correct Replacement Suspension Components for Tandem Axle Boat Trailer
    Thank you for submitting the photo of your boat trailer showing the center spring hanger, shackle straps and equalizer. Based on the photo it does appear that non-standard replacement parts may have been used to repair or modify the suspension at some point and this could certainly have contributed to the rear axle tire failure. If the equalizer cannot function correctly (due to the use of fabricated or non-standard replacement shackle straps) then too much of the total trailer load may...

  • 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.

  • 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.

  • Why Are Axles on Horse Trailer Further Back
    There are a couple reasons why you typically see the axles on a horse trailer further back than on a standard cargo or flatbed trailer. The first reason is to try and maintain the trailer's weight distribution as best as possible during travel. Since horses may move around a bit or sit down, having a shorter rear overhang helps to keep everything more stable. This shorter overhang also helps when it's time for the horses to climb in for their ride. Since the rear won't move as much...

  • Determining Axle Position on Sailboat Trailer
    In general when positioning a trailer axle you just want to make sure that roughly 10 to 15 percent of the total weight (with the boat loaded) is placed on the tongue. Typically on boat trailers this means the axle(s) will be set further back than on a traditional trailer because the back of the boat is usually heavier. Getting the ideal placement usually takes a bit of trial and error so it might be a bit difficult to get everything set up perfectly before actually having the sailboat...

  • Determining Spring Hanger Spacing for Tandem Axle Trailer Fabrication Project
    Thank you for the measurements you provided and for the photo of your trailer suspension mockup showing the spring components' spacing. As long as your shackles do not hit the trailer frame (you mention 1/8-inch clearance) you should be fine, but if you'd like a bit more breathing room you could increase spacing from 29-1/2 to 30-inches without negatively affecting anything else.

  • Where Should Front And Rear Suspension Hangers Be Welded On A Tandem Axle Trailer With 23" Springs
    With the equalizer that comes included with the Tandem-Axle Trailer Hanger Kit for Double Eye Springs # APT5 measuring 7-3/4 inches long (from eye to eye) and your leaf springs measuring 23 inches long, you will want to mount the front and rear hangers 28 inches from the middle of the center hanger. This will allow the shackle straps to sit at the correct position and move with the equalizer properly.

  • Is There a Specific Hanger Recommendation for a 5,200 lbs Tandem Axle Trailer

  • 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...

  • Should Trailer Suspension Equalizers be Level
    If the trailer is not loaded then you will often see equalizers that are tilted like yours. It does not necessarily mean that there is a problem with the suspension. If the springs are worn out then the trailer would easily bottom out. If that is not happening then the springs are likely fine. It is possible that some component is not the right size as well. If the springs are too short or the equalizers are not long enough that can affect the geometry of the suspension.
