Features to know about

Stable Suspension for Tandem Axles: 13-1/8" Equalizers Keep Things Balanced

A rough ride or uneven weight transfer can wear down your suspension fast. This kit includes two 13-1/8" long straight equalizers that connect your tandem axles so they flex together over bumps and dips. The equalizers use a 7/8" diameter center hole for mounting to the hanger and 9/16" side holes for attaching the springs, giving your setup the precise geometry it needs for steady, balanced movement.

Reliable Mounting Every Time: Hangers Sized for a Solid Fit

Getting the hangers right is key to how your suspension performs. This kit comes with front hangers measuring 3-9/16" tall from top to bolt-hole center, center hangers at 3-3/8", and rear hangers at 5-1/6". The mix of heights matches the natural arc of the slipper springs so the suspension cycles smoothly without binding or bottoming out.

Built for Tandem 3,500-lb to 8,000-lb Axles: Heavy-Duty Hardware Included

For a setup that can handle real weight, this kit is designed for trailers running tandem axles rated from 3,500 lbs to 8,000 lbs. It includes all the mounting bolts, locknuts, and pins needed to hang the springs securely—(2) 3-1/4" long × 5/16" diameter spring keeper bolts with locknuts, (6) 3-1/2" long × 9/16" diameter shackle bolts with locknuts, and (2) 4-1/2" long × 7/8" diameter wet equalizer bolts with matching locknuts and cotter pins. Everything works together to keep the springs tight and the suspension aligned under heavy loads.

Smooth Travel and Easy Maintenance: Straightforward Design That Works

When you’re upgrading or replacing worn mounts, this kit makes it simple. The components attach four 2" wide slipper springs (sold separately) to your trailer frame using clean, proven hardware. It’s a direct, no-nonsense setup that restores the suspension’s smooth movement so you can tow level and steady mile after mile.

Video Transcript for Hands-On with the Tandem-Axle Trailer Hanger Kit for 2" Slipper Springs

Hello, everybody, this is Jeff at etrailer.com. Today, we're gonna take a look at the Dexter Tandem-Axle Trailer Hanger Kit for two inch wide slipper springs with 36 inch axle spacing. Now this leaf spring mounting kit is designed to attach four two inch wide slipper springs on trailers with tandem 3,500 pound up to 8,000 pound axles. Now, the slipper springs are not included. Those we do sell separate on our website. This part here is just the leaf spring hanger kit, and it includes everything that's shown on the table.

We're gonna go through all these pieces so just so you know what you're all getting, and we're gonna start with the hangers. We'll start with the front hangers, which are these two right here. These are 3 9/16 inch tall front hangers. And when we say the height of a hanger, when you measure it, it's not the bottom to the top. It's measured from the center of the bolt hole to the top of the hanger.

So if we get a ruler, and if we go center to the top, that'll give you 3 9/16 inch measurement for the front hangers. The center hangers, which are these right here, same way when we measure 'em, center to the top, 3 3/8 inches on the height of the center hangers, and the rear hangers right here, if we measure those, center to the top is 5 1/16 inches tall in the rear hangers. Now the equalizers, which are these two long equalizers right here in the middle, these are 13 1/8 inches long. And again, put a tape measure on that, 13 1/8 inches in the length, straight equalizers. Now, if you notice on the equalizers, these attach to the center hangers and it'll have a 7/8 inch diameter center hole here for mounting to the hanger using the wet bolts there.

On this set, it'll have 9/16 diameter end hole for attaching to the spring. And on right down here on the other end, a 5/16 diameter end hole for the spring keeper bolts for the slipper spring to sit on. Now the hardware, we mentioned it comes with the two wet equalizer bolts that are 7/8 inch diameter, 4 1/2 inches long, with the lock nuts and the cotter pins. These wet bolts can be greased, we call 'em wet bolts 'cause they have a grease circuit fitting that you can attach a grease gun to and lubricate 'em, and this is what'll attach the equalizers to the center hangers. The shackle bolts, there's six shackle bolts, four over here, two over here, with the lock nuts.

These are size 9/16 inch diameter by 3 1/2 inch long shackle bolts. And then the two spring keeper bolts, which are 5/16 inch diameter by 3 1/4 inch long, with lock nuts also. Now the equalizers, the 13 1/8 inch long equalizers allow for 36 inch axle spacing. Now this kit does not include any components for mounting your axle to the springs. But that should do it for the review on the Dexter Tandem-Axle Trailer Hanger Kit for two inch wide slipper springs with 36 inch axle spacing.

Second time was the charm. The reorder came today and it was the correct item this time. The representative that fixed the order and got the correct item out to us was very helpful.



by:

item is as described. We have it on an asphalt hot patcher, so it does get used quite hard. Wish it were just a little heavier.



by:

Great product and fast shipping.



by:

Right product, perfect fit,fast service



by:

Well made, good weld beads, but some of the spring perches could have used more weld. I added more in myself and am satisfied with it now.



by:

The website site was very detailed, which made getting the right parts very easy, such as dimensions, load capacities, etc. also pictures were very clear of each product which was very helpful getting to the right product fast. prices were competative and 95% of the time cheaper. I will recommend etrailer to anyone i know with trailer needs. Arrival time of my parts was way sooner than expected, which is going to get me up and running for business sooner than expected. Great job to every department and everyone at etrailer!! Soon i will have before and after pictures of each product installed. Thanks etrailer.

The product look very high quality and fit as it said it would so good job



by:

It has been almost a year before we got the hangar kit installed on an old trailer. I don't weld very good so had to wait for my son to get time to come up and put them in. They worked perfectly on the stretched 7k axles we put on in place of the 3.5k axles that were on the trailer originally. Once we got wheels and tires to fit, we loaded a tractor with a loader on the trailer and everything worked like it should. We have been very happy with the service from etrailer, having purchased a couple sets of hanger kits, equalizer bolts, trailer hitch and other trailer items. Very happy with their timeliness in getting our orders shipped out!

  • 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.

  • Slipper Spring Trailer Suspension Hanger Spacing
    There is not a fixed spacing for the hangers in kit # APT6SE-36 since this depends on the length of the particular springs used. The hangers need to be close enough together that the curved ends of the slipper springs properly engage with the bolt or column they rest on. Please refer to the linked image, dimension B, to see this spring dimension. Measure this on your springs to get the approximate distance from the center of the spring eye to the highest point of slipper end.

  • Steel Thickness of Components Measured at 7/8 Inch
    Hi, I went out to our warehouse and measured the steel on these components for you. The Tandem-Axle Trailer Hanger Kit for 2" Slipper Springs part # APT6SE-36 measures approximately 7/8 inch thick. I hope that helps with your project! Are you looking to replace your hanger kit? I am happy to help.

  • Does Tandem Axle Slipper Spring Hanger Kit # APT6SE-36 Work with Springs that are 2 inches Wide
    We have one 6,000 lb axle rated slipper spring that is 2 inches wide. For that you would want the part # e67SR that is 27 inches long. The ends of this spring are hooked but do not come all the way back around like a C shape like what it sounds like you have. However, both styles are acceptable and will install in the same way. The tandem axle hanger kit part # APT6SE-36 that you referenced will work with what you have since you said your springs are 2 inches wide. I also attached a link...
