Features to know about

Better Ground Clearance and Tire Space: Taller 3-1/4" and 3-5/8" Hangers Lift the Setup

If your tires are rubbing or you need more room under the trailer, this hanger kit is built to help. The front and rear hangers stand 3-1/4" tall, and the center hangers are 3-5/8" tall, giving your suspension a little extra height where it counts. That added clearance helps protect plumbing and underbody parts when you’re on uneven ground or backing up steep driveways.

Smooth Suspension Movement: 5-3/4" Equalizers Keep Axles Working Together

A solid suspension setup keeps both axles moving in sync. The 5-3/4" long curved equalizers in this kit balance the load between axles so bumps are absorbed evenly. The result is a steadier ride with less bounce and sway when towing over rough surfaces.

All the Core Hardware in One Kit: Ready to Mount Double-Eye Springs

This kit brings everything you need to hang your leaf springs and equalizers. It includes (4) 3-1/4" tall front and rear hangers, (2) 3-5/8" tall center hangers, (2) 5-3/4" long equalizers, (8) 2-1/4" long shackle straps, (14) 3" x 9/16" shackle bolts, and (14) 9/16" locknuts. It’s designed for use with tandem 2,000-lb to 7,000-lb axles, so you can build or refresh the suspension with properly matched parts.

Right Spacing for Proper Geometry: Designed Around Proven Hanger Distances

Getting hangers set in the right place makes all the difference in how the trailer tracks and rides. This kit is designed to set your hanger spacing for double-eye leaf springs so the suspension cycles smoothly. Depending on your axle size, you’ll get about 4-1/2" to 5" of clearance between the frame and axle for reliable performance mile after mile.

I decided to reuse the existing brackets to save some welding, but all of the bolts and the equalizer went on without an issue and seemed to be of Excellent quality. I expect to be able to keep my 50 year old trailer for another 50 years.

After a year of usage the horse trailer is still doing its job - no issues with the bolts or the equalizers. Everything has held up well.

I purchased parts for my 14'x7'enclosed trailer as spares just in case I have a problem while on the road. I am planning a 12500-mile trip this summer and want to be prepared for any potential breakdown. The kit has all the parts necessary to attach two axles and 4 springs to a trailer. The parts are high quality and match the factory Dexter axle parts on my trailer exactly.
by:
The AP233-H248 axle hanging kit came super fast. It was the correct size and excellent quality. I didn't think about ordering spring eye bushings, but that is nobody's fault but mine. I'm planning to order from etrailer.com again.

Worked for a tandem 3500lb HD axle

Great setup. I went with a single thick spring for my boat trailer, so less area to rust. So far it’s perfect.
by:
Great improvement, every trailer should leave the factory with these installed!

Also cut and welded crossmembers between spring hangers.

No sway, no twisting from front to back of RV

Patrick, well it went on a boat trailer which doesnt get used alot but i have had no problems what soever so far. all good.

I t fit perfectly to replace my old 40 year wore out trailer suspension.
Reason for only 4 stars is the shipping boxes are Chinese cheap and a bolt was missing from shipping Kaos

I was able to get one from a local trailer supply.

They need to step up to a better grade of shipping container nobody likes to get their stuff with Parts missing

great product and fast service

Good weld on kit. Good quality. It’s working great!

Using the hangers to restore an old trailer. The only problem I ran into was that my six leaf springs have three quarter inch bores and the standard bushings are eleven sixteenths. I'll have to machine something for that. Shipping was excellent and here before I was ready. Thanks
by:
I received an email on the conformation of the order very quickly. The order was thenprocessed the very next day, and sent out. I received the parts well before the original due date. The parts were in good condition, and the heavy parts we stapled to the shipping box so they wouldn't move around and damage the other parts. Excellence care.
I won't be able to install the parts. By the looks of the parts, they look like they will fit properly and be exactly what the trailer needs. Thank you again for the prompt and caring service. I will highly recommend you.

i built a 20 foot tandem axle flat-deck trailer wanted to put new hangers on it etrailer sent me exactly what i needed and had helpful info on installing my parts made it real simple il be buying all my trailer parts from etrailer from now on. thank you etrailer.
by:
the box with the hanger kit had been very wet at one point and the parts inside had started to rust. It didn't happen in the bigger box it was shipped in because the smaller box with the spring mount kit was fine. The parts are usable but whoever packed it new what they were shipping.

After a year of use, still going strong. Have taken the trailer over many bumpy dirt roads every month.

Great product. I have used etrailer several times and could not be happier with their service and products. They are my "go to" for all my trailer needs.
by:
This is my second order with Etrailer.com and like before the products are a good value. I will be ordering more in the future. I will send pictures once these parts are installed.
by:
Placed order on 6/18 with very knowledgeable sales person ( sorry I can`t remember her name) my complete order came on 6/22 with free shipping.
by:
The parts are great quality and showed up to my door very fast. Furthermore, the etrailer team was super helpful when the exact part I needed wasn't going to be stocked for another 2 months. The etrailer team caught this before I even noticed and suggested an alternate option that would work equally as well and it was in stock.

You Guys ROCK!
by:
I have not installed these yet but am very impressed with how heavy duty they appear. They surpass the ones I am replacing which have failed due to being too light duty.
by:
Received my order in a timely manner and was happy with the ordering process, But was disappointed in the product. The hangers were not bent right and I had to use my hydraulic press to rework the bends to get the angles right and the holes aligned.
by:
Great web site, great advice, great prices, great shipping- it’ll be great to get an old trailer back on the road!!
by:
Decent product for the price, trailer they went on is not finished yet due to other obligations.

  • Entire Suspension Set Up For Tandem 3" Diameter Axles
    Hello Francis. Thanks for sending in the pictures. With the axle being 3" diameter tells me that they are 5,200-7,000 lbs. I have a solution for you, but you probably aren't going to get too excited about it. Your best bet is to replace everything, and it's because of the leaf springs. The only 2" wide leaf springs we carry are all slipper springs. Here is the set up I would do: First you want to start with the Tandem-Axle Trailer Hanger Kit # AP233-H248, this kit is going to get you...

  • Leaf Spring Recommendation for Single 3,500 lb Axle Converted to Tandem Setup
    Hey Dale, I would go with a 2,000 lb rated spring like the etrailer part # e77SR if you were to switch to a tandem setup. This will still be more capacity than needed overall but won't be so overkill that ride quality suffers. Then for a hanger kit the part # AP233-H248 would be a really great option that comes with everything you'd need to mount up a second axle and leaf springs. To pick out a replacement axle though you would need to know the distance from hub face to hub face as well...

    To attach your axles to the the frame of the car hauler you will need the Tandem-Axle Trailer Hanger Kit for Double-Eye Springs # AP233-H248. This kit includes all the hangers, equalizers, shackle straps, shackle bolts and nuts to fit your axles. I have linked an article below that will help you with positioning the axles on your trailer to ensure that you have the correct percentage of tongue weight when towing to be safe.

  • How Much Space Should be Between the Top of the Axles and the Bottom of a Boat Trailer
    Normally when using hanger kit # AP233-H248 with spring # e66SR the distance from the bottom of the frame to the center of the axles is going to be approximately 4-1/2 inches. Subtract half the width of the frame then to the top of the axles that would be 3-5/16 inches. Two inches might work out fine depending on how far the suspension travels but more height would likely be needed considering the heavier load. Hanger kit # APT4 would provide more height since it has taller hangers than...

  • Replacement Suspension Parts Needed for Atlas Trailer with Tandem 3,500 lb Axles
    It sounds like you have this hanger kit # AP233-H248 installed on your trailer, which has the hangers spaced out by 29-1/2" on center. We don't have the exact specs from trailers that have been made over the years so you'll want to confirm this on your end of things.

  • Tandem Axle Hanger Kit Recommendation that has 5-3/4 inch Center Hangers
    For a trailer suspension kit that comes with 5-3/4 inch equalizers you would want the part # AP233-H248 instead of the # APT5. Aside from that and the center hangers being slightly different to accommodate the different equalizers the kits are the same.

  • Replacement Suspension Parts for Tandem Axle Travel Trailer
    The 3,500 lb axle is the most common size 2-3/8 diameter axle, but it isn't the only one. If you have the odd-ball 2,800 lb axle, then you will have the different bearings, seal, and hubs you referenced because of the spindle dimensions. Each axle is rated individually by the manufacturer and the spindles are in the case the reason for the lower rating. The springs you currently have are not available from our manufacturers in the size. You will need to replace the hangers as well...

  • Tandem Axle Trailer Suspension Hanger Kit To Provide More Axle Clearance
    It sounds as if your trailer suspension was built with the common Tandem-Axle Trailer Hanger Kit, # APT3, and that the springs and attachment hardware are wearing out enough that with the weight you are carrying there is no longer enough room for the suspension to work without contacting the trailer frame. I would recommend stepping up to the Heavy Duty Tandem-Axle Trailer Hanger Kit, # APT3HD, or the Tandem-Axle Trailer Hanger Kit, # AP233-H248. The # APT3HD kit comes with 2-1/2 inch...

  • Solution for Needing Replacement Leaf Spring for 5,000 lb Axle
    I wish we could help with the axle but we don't have any straight axles in the dimensions you need nor do we have any leaf springs that are 58 inches long. Most of the current leaf spring dimensions are about half that so what you'll most likely have to do is install new hangers to use a modern size leaf spring like the # e44SR which is for a 5,000 lb rated axle and is 25-1/4 inches long from eye to eye. For a tandem axle hanger kit you could use the part # AP233-H248 which comes with...

  • Hanger Kit for Tandem Axle Trailer that Needs More Wheel Clearance
    Since you said your tires were rubbing I would go with a hanger setup that is a little taller like the part # AP233-H248 which has 3-1/4 inch front/rear hangers and 3-5/8 inch center. Also, while the 60/40 rule for axle placement is a great starting point it's no the end-all-be-all for placement. The best location for the axles will be where the weight of the trailer will have it's tongue weight as 10-15 percent of the total trailer weight.

    The Dexter axle part # 35545I-ST-89 is a 3,500 lb trailer axle so for a leaf spring that would work well with that you'd want the # e45SR which is the same rating and is 25-1/8 inches long. Then for a tandem hanger kit you'd want the # AP233-H248 and the U-bolt kit part # CE23002.

  • Will Trailer Suspension Hanger Kit # APT5 Fit a Trailer with 2-3/8 Inch Diameter Axle
    You can use the Tandem-Axle Trailer Hanger Kit # APT5 for your trailer with the 2-3/8 inch axle. A 2-3/8 inch diameter axle is typically found on 3,500 pound axles which is within the range of this kit (2,000 to 7,000 pound axles). The measurements in the chart on the page can be used as a guide. A better option for a 2-3/8 inch axle is kit # APT3, # AP233-H248, or # APT1. It all depends on the axle spacing, spring measurements, and equalizer length.

The kit you will want to use is the Tandem-Axle Trailer Hanger Kit for Double-Eye Springs # AP233-H248. This kit includes 2 of the 5-3/4 inch curved equalizers like you referenced. Also included are shackle straps, shackle bolts, and lock nuts. The included hangers measure 3-1/4 inches tall for the front and rear, and 3-5/8 inches...

  • Trailer Suspension Kit and 6 Inch Long Equalizers for Tandem Axles and Double Eye Springs
    Suspension kit # APT4 for tandem axles with double eye springs has 6-1/4 inch long equalizers so it is a possible option for you. Kit # AP233-H248 uses 5-3/4 inch long equalizers. But if you have to have equalizer # TREQ310 then the individual parts will have to be pieced together since there isn't a kit with that equalizer. If you go that route then you would also need: 8 of # 18-11GALV 14 of # 166081 1 of # H248 (or other hangers, see link)
