Video Transcript for etrailer Trailer Suspension - Leaf Spring Suspension - APS4 Review

Today we're going to take a look at the Single Axle Trailer Hanger Kit for double eye springs. Now this leaf spring mounting kit includes the 3 1/4" tall front hangers, the 1 1/4" tall rear hangings, and all the necessary hardware for installation. This will attach two leaf springs to your trailer frame. We sell the leaf springs separately on our website. Basically to determine the hanger location on your trailer, we do have a table at the bottom of this product page that will show you measurements that are required based on the types of leaf springs that you use. This part will achieve 5" or 5 1/2" clearance between your trailer frame and your axle, depending on your axle size you use, and includes all the parts showing here. It includes the two 3 1/4" tall front hangers.

Now when they say 3 1/4" what they're measuring is from the center of that hole to the top here. If we put the ruler on, you can see there's your 3 1/4" measurement. The two 1 1/4" tall rear hangers, and same way from the center of the hole to the top. There's your 1 1/4" measurement. The shackle straps is four 3 1/8" long shackle straps.

The shackle straps are measured from center to center. There's your 3 1/8". It comes with the hardware, the six 3" long by 9/16 shackle bolts, and the six 9/16 diameter lock nuts. Now this part is designed for use on trailers with 2,000 pound to 7,000 pound axles, and it does not include components for mounting your axle to the springs. That should do it for the review on the Single Axle Trailer Hanger Kit for double eye springs.

Product arrived just as described and very quickly. This kit was a great way to drop the springs on our trailer enough for the axle to be put on correctly. 229667

I bought springs, mounts and Tailight kit to fix up a rusty utility trailer. I cut, weld scraped and painted for the better part of a month in spare time. The springs and mounting instructions on e trailer are excellent. Only issue/shortcoming are the tail lights. Wire just pushes in and spring loaded strip holds them. I soldered and sealed the connection with silicone. So far that salt covered roads haven't hurt it in winter. The folks at etrailer are very helpful and prices are a good value. 426532

I inherited an aluminum trailer that ended up needing a complete overhaul and etrailer was the best resource I could have found. After researching extensively to find out what I needed and watching their videos on how to do it I ended up ordering an EZ-lube axle, galvanized hubs, springs and a hanger kit (in other words everything from the frame down). Everything shipped quickly and arrived in great shape. All the parts worked perfectly and I couldn't be happier! 316659

The hangers look good and I believe they will do a great job. I need to move my axle back on my trailer so it will be able to haul some weight. It is a dump style body and can't handle weight, only on the front of the trailer. So I am going to move the axle back about 6 to 8 inches. The tracking info on the kit was great... ALL gratitude goes to your company... 495832

Ask the Experts about this etrailer Trailer Leaf Spring Suspension
Do you have a question about this Trailer Leaf Spring Suspension?


  • Trailer Leaf Springs, Hangers, and U-bolts for a 3,500 Pound Axle
  • It does appear that the hanger in the picture has been overloaded or otherwise damaged so replacing them is a good idea. And like you said, since it has to be replaced anyway you could switch to double-eye springs which are more common so parts for them are easier to find. The springs do not have to be the same length but having it close means you won't have to do any math to ensure everything is in the best location for the trailer size and weight. You can use hanger kit # APS4 which...

  • Replacement Parts to Rebuild Trailer Suspension on 1976 EZTrail
  • All of the products you listed will work together just fine. Keep in mind, if your current springs are not 26 inch springs, like the # SP-124275 you referenced, your hangers, # APS4, will not be in the exact same position as your current ones. When repositioning everything the most important factor is keeping the axle in the same location it currently is. The U-Bolt Kit # APUBR-10 is correct for a 2,000 pound axle and the Shackle Bolt # 166081 will work too. It's hard to tell by the...

  • Do the Shackle Straps Go Inside or Outside the Leaf Spring Hanger
  • The shackle straps need to be placed on the outside of the rear leaf spring hangers which you can see in the attached photo. Furthermore, the distance between the two mounting plates (inside to inside) on your leaf spring hangers should be 1-7/8", not 2" which is most likely why there is too much of a gap between the shackle straps and leaf spring. Therefore, the leaf spring hangers will need to be replaced. For this, we generally kit the single axle trailer suspension hangers and shackle...

  • Replacement Trailer Axle for a 5x10 Utility Trailer
  • Unfortunately, we do not have any hubs that match the dimensions you provided. The only other option I have for you at this time would be to replace the axle. If you can provide me with the hub face to hub face and spring center to spring center measurement, I can go about trying to find a replacement axle for you.

  • How to Determine Leaf Spring Hanger Placement on a Single Axle Trailer
  • Generally speaking, on a single axle trailer you will want the leaf spring hangers to be spaced apart 1/2" less than the eye to eye measurement of your leaf spring. Therefore, you will want to place the hanger 25-1/2" apart on center when using the 4-Leaf Double-Eye Spring part # SP-124275 with the Single-Axle Trailer Hanger Kit part # APS4. Please keep in mind that you will need to determine the correct position of your Dexter Trailer Axle part # 20545I-EZ-72-15 before welding the leaf...

  • Recommended Parts for Rebuild/Upgrade of Harbor Freight Trailer
  • The Dexter Trailer Idler Axle w/ Hubs - EZ-Lube - 5 on 4-1/2 Bolt Pattern - 60" Long - 2,200 lbs # 20545I-EZ-60-15 is a great starting point to upgrade your trailer. This will give you a standard size axle with good bearings, hubs, and EZ-lube spindles. This is far nicer than the weird sized stuff that comes on Harbor Freight trailers. The Karrier ST175/80R13 Radial Trailer Tire with 13" Galvanized Wheel - 5 on 4-1/2 - Load Range D # AM31994 will be a great addition to these hubs...

  • Installing Leaf Springs on Single Axle Trailer
  • For a single axle trailer, you want the shackle strap to be able to move so that you have the spring deflection needed for your suspension. Angled like the photo or even almost vertical is fine you just don't want the shackle strap to bind and have issue as you go over bumps. If it is completely vertical or angled back toward the axle, then your leaf spring is not long enough and your suspension components will not move as intended giving you a rough ride at best and at worst failure...

  • Can Trailer Suspension Hangers be Bolted On
  • The top holes you see in trailer suspension hangers such as Single-Axle Trailer Hanger Kit for Double-Eye Springs - 1-1/2" Front, 1-1/4" Rear Item # APS3 are for button welds and not bolts so these hangers should not be bolts on. The problem is that with a weld the hanger is fixed and cannot move. With bolts no matter how tight you make them the bolt will always be smaller than the holes in the hangers and given the forces applied could cause the hangers to shift and throw off the alignment...

For the leaf spring, I recommend using the 3-Leaf Double-Eye Spring part # SP-219275. For the suspension kit, I recommend the Single-Axle Trailer Hanger Kit for Double-Eye Springs part # APS4.

If you check with a local trailer garage/store they should be able to help you order one that has a galvanized finish that also have the correct hub-face and spring-center measurements for your application. A 3,500 lb axle should use inner bearing L68149, outer bearing L44649, and a grease seal that has an inner diameter of 1.719" and an outer diameter...

In your required 9/16-inch diameter the longest bolt we have is the Redline # 34007-187-00 which is 3-7/16-inches. The 4-inch and longer shackle bolts are different diameters, such as the Redline # 38-4TB which is 4-inches x 3/8-inches diameter.

It is rated for use with a 2,000 lb trailer axle so your weight rating of 1,750 lbs will be no problem. To install this on your trailer you will need a suspension kit like part # APS4.

Since your boat weighs 3,000 lbs and we have to factor in the weight of your trailer the # SP-256275 would be a great choice as it is a 4,500 lb axle spring.

This of course will only work if the leaf springs are mounted to the bottom of the trailer now. What this kit does is allow you to put the springs on top of he axle without flipping the axle or welding. Otherwise what you could do is use taller hangers. All of the hangers would have to be raised the same amount. So...

  • Switching From Slipper Springs to Double-Eye on a Single 2K Axle Trailer with Square Axle
  • To switch to double-eye spring suspension I recommend getting parts individually since the u-bolts cannot be swapped out of kits. The spring in the kit is # SP-169275. We have a few different u-bolt kits for square axles including # CE23102 for 1-1/2 inch square axles. For a 1-3/4 inch square axles you can use u-bolt # 175130 and plate # 116308. And for 2 inch square axles we have # CE23103. You will also need a new hanger kit since double-eye springs use different hangers than slipper...

That is a pretty small trailer, are you sure you want to go with such heavily rates springs? Going with higher rated springs will only give you additional spring capacity.

  • What Is The Proper Hanger Spacing For A 3 Leaf 1,750 lb Capacity Leaf Sping
  • The spacing of leaf springs varies depending on how many axles are on your trailer and the position of the spring. For a 3 leaf, 1,750 lb spring like part # PR3 the hanger specifications in the Redline Trailer Supplies Catalog are as follows: Single axle - 25-3/4 inches Tandem axle - A=29-1/2 - B=29-1/2 Triple axle - A=29-1/2 - B=34 - C=29-1/2 The recommended hanger kit for a single axle trailer is Single Axle Trailer Hanger Kit, part # APS1, or part # APS4. For tandem axle, the...

  • Typical Trailer Suspension Hanger Spacing Relative to Leaf Spring Size
  • On single axle trailers typically you put the hanger spacing right at 1/4 of an inch shorter than the leaf spring length from eye to eye center. So if you were using the leaf spring part # SP-212275 that you referenced which measures 25-1/8 inches long from eye to eye unloaded the hanger spacing you'd want to use would be 24-7/8 inches. The hanger kit for this leaf spring typically is the part # APS4.

If you have a 2-3/8" diameter axle then you will want to use the Dexter Trailer Springs Over-Under Conversion Kit part # K71-384-00 instead.

  • How Far Apart Should Hangers be Mounted for 27 Inch Leaf Springs
  • If your Double-Eye Leaf Springs are 27 inches long, you will just want to mount the hangers in the Redline Single-Axle Trailer Hanger Kit # APS4 mentioned in your question about 26-1/2 inches apart. As a general rule, you want the distance between hangers on a leaf spring suspension system to be around a 1/2 inch shorter than the distance of your leaf springs, which will allow for some movement with the shackle strap.
