Video Transcript for etrailer Trailer Suspension - Leaf Spring Suspension - APT6SE Review

Today we're going to take a look at the Tandem-Axle Trailer Hanger Kit for two inch slipper springs, with the 12 inch long equalizers. Now, this leaf-spring mounting kit will include a 3 3/4 inch tall front hangers, the 3 3/8 inch center hangers, the 5 1/6 inch tall rear hangers, and all your necessary hardware to install it. The equalizers themselves, are 12 inches long. Now, this part will attach four leaf-springs to your trailer frame. The leaf-springs we do sell separately. Now, on the product page of this part number, if you use the table at the bottom of the product page, that will help determine your hanger location, based on the type of leaf-springs you use. This part will achieve 4-1/2 inches or 4-3/4 inch clearance between your trailer frame and axle, depending on your axle size. It includes all these parts shown here.

I'm going to try to go through them all here, to show you what they go to. We'll start with the tall front hangers right here. There's two of them, they're 3-3/4 inches. The way that's measured, is you measure from the center of the hole to the top of the bracket, so there's your 3-3/4 inch front hangers. The tall ones, right here, those are the rear hangers. There's two of those.

They're 5-1/6 inches, so center, there's your 5-1/6 inches on the rear hangers. The two right here, the center hangers, these are 3-3/8 inches. Again, we'll center, there's your 3-3/8 inches. The 12 inch long straight equalizers, right here, we'll go ahead and put a ruler on those. You can see 12 inches in length. Now, the hole, right here, the larger hole, is a 7/8 inch diameter center hole.

That's for mounting the hanger to. Basically, when you put your hanger in there, that's where that would go. The holes on the side, these are for attaching the spring to. Those are 9/16 diameter side holes. Also, comes with the eight 3-1/2 inch long 9/16 diameter shackle bolts, the 8-9/16 diameter lock nuts. Now, it does come with the large 7/8 inch diameter equalizer bolts.

There's two of those. These are what would be used when you put your, to your equalizer. You just run them through, just like that. Then, once you get it through, you have it just like that. Also, comes with the castle nuts that will go on the end; two castle nuts, 7/8 inch diameter. Then two cotter pins that would go in there once you get the castle nut tightened correctly. Now, this is designed for use on trailers with tandem 3,500 to 8,000 pound axles. It does not include the components for mounting the axle to the springs. That should do it for the review on the Tandem-Axle Trailer Hanger Kit, for two inch slipper springs, with the 12 inch long equalizers.

Ask the Experts about this etrailer Trailer Leaf Spring Suspension

Do you have a question about this Trailer Leaf Spring Suspension?


  • Spacing Between Hangers With Slipper Springs for 8,000 lb Axles and Hanger Kit
  • I checked for you and when installing the 7-Leaf Slipper Spring w/ Hook End for 8,000-lb Trailer Axles # SP-285275 with the Tandem-Axle Trailer Hanger Kit for 2" Slipper Springs - 12" Long Equalizers # APT6SE the distance between the front and center hangers will be 28-1/2", the distance between the center and rear hangers will be 29-1/2", the distance between the U-bolts will be 33" and distance between the center of the axle and trailer frame will be 4-1/2". I made a diagram for you...

  • Recommended Triple or Quad Axle Suspension for Trailer Build
  • Since you are building a trailer I first want to state that using quad axles isn't ideal. It will cause tire scrub as there becomes too broad an axle base for the trailer to track as nicely. That is why most trailers will use tandem or triple axles as needed for load capacity. If you just want to add the 4th axle for overbuild reasons it will bite you as you will need to replace tires more often. Most of the professional semi flat bed trailers that have the quad axles are for transporting...

  • Axle Spacing When Using Slipper Spring Equalizer Kit # APT6SE with 26 inch Long Leaf Springs
  • Based on your leaf spring length the axle spacing you'd have with the hanger kit part # APT6SE would be right at 33 inches. This kit is designed for use with 9/16 inch bolts like the # 166079 and we would not recommend drilling out the kit to fit a wider bolt.

  • Hanger Spacing when Using 12 Inch Long Slipper Spring Equalizer E4541-Z
  • It really depends on the springs used. Take a look at the picture I have included that shows hanger spacing based on several different springs. This will be a good guide to reference when mocking up the suspension on your trailer. This is also found on suspension kit page for # APT6SE.

  • Recommended Hangers for Slipper Spring Suspension
  • The 4-Leaf Slipper Spring w/ Open Eye End for 4,300-lb Trailer Axles - 26-1/4" Long # SP-264275 is a 1-3/4 inch wide spring, so I recommend using the Single-Axle Trailer Hanger Kit for 1-3/4" Slipper Springs # APS3SE for these springs if you have a single axle trailer. If you have a tandem axle trailer, you will want to move to 2 inch wide springs like # SP-231275 and use a kit like # APT6SE.

  • Tandem Axle 2 Inch Slipper Spring Suspension Kit with 13-1/8 Inch Long Equalizers
  • You will actually just need kit # APT6SE-36 which is the same thing only the equalizers in it are 13-1/8 inches long. The hardware with each is specific to the kits so some of the other parts are different but for 2 inch slipper springs and 13-1/8 inch equalizers kit # APT6SE-36 is the one for you.

  • Recommended 8,000 lb Slipper Spring Hanger and Equalizer Kit for 2 Inch Springs
  • For your Tandem 8K axles with 2 inch slipper springs, I recommend the Tandem-Axle Trailer Hanger Kit for 2" Slipper Springs - 12" Long Equalizers # APT6SE. The hangers are to be welded to your trailer frame and the holes on the top of the hangers are for spot welds not bolts. This kit comes with the hardware needed.

  • Can Tandem-Axle Trailer Hanger Kit APT6SE Replace 11-1/4 inch Equalizer
  • Are your hangers attached to angle-iron beams that run from side to side on your trailer? That's a pretty unique setup if so. It almost looks like the front one is bent? The equalizer of the kit part # APT6SE that you referenced would work well to replace what you currently have though. This kit does not need bushings provided separately as they are not needed.

  • Thickness of the Equalizer in the Triple-Axle Trailer Hanger Kit # APTT6SE
  • I went and pulled the Triple-Axle Trailer Hanger Kit # APT6SE from our warehouse to measure the thickness of the equalizer in the kit and found it to be 1/4 inch thick. The equalizer is made by the company Redline.

  • How to Determine Axle Spacing on a 5,000 lb Tandem Axle Trailer
  • The exact axle spacing will depend on the hanger kit and leaf springs you are using. For example, for a trailer with two 5,000 lb axles, we recommend using hanger kit, # APT6SE, and 4-Leaf Slipper Springs for 5,000 lb Axles, # SP-231275. The spring length and equalizer length will play a big role in determining axle spacing. The hanger kit comes with a 12 inch long equalizer and the 5,000 lb slipper springs are 24-5/8 inches long. For this combination, the distance between the front...

  • Hanger Spacing Dimensions for Installing E5115 Slipper Springs on Tandem Axle Trailer
  • I was able to find more info on your slipper spring. Looks like you have a Dexter 5115 slipper spring that is 27-1/2 inches long and has a 4k capacity. I attached a picture that has all of the hanger spacing dimensions needed when installing this spring with a hanger kit that uses 12 inch equalizers. The hanger kit you most likely have is the part # APT6SE.

  • How to Determine Hanger Spacing on 5,200 lb Tandem Axle Trailer
  • For this combination, the distance between the front hanger and the center hanger should be 32 inches on center. The distance between the center hanger and the rear hanger will be 32 inches on center. This will put the axles 36-3/4 inches apart on center and the center of the axle will be 4-1/2 inches below the trailer frame. Take a look at the image I made for you which shows the spacing you will want for your hangers.

  • Tandem Axle Hanger Kit for 2 inch Wide Slipper Springs
  • Yes, you can mount two 6,000 lb capacity axles that use slipper springs in tandem on your trailer. What you'll need is a tandem axle slipper spring hanger kit like the part # APT6SE which is designed for 2 inch wide springs like what you have. What equalizers do is prevents any of your axles from ever carrying the full weight of the trailer at any time like over a bump. The weight is always "equalized" between the two axles.
