Features to know about

Lower Ride Height for Easier Loading: 1-1/2" Front/Rear and 2-1/2" Center Hangers

Getting a trailer low enough to load cars or heavy gear safely can be tricky. This hanger kit makes it simple with 1-1/2" tall front and rear hangers and 2-1/2" tall center hangers that keep the deck closer to the ground. It’s a solid setup for tandem systems where a lower ride height improves stability and loading angle without giving up suspension travel.

Smooth Suspension Movement on Uneven Ground: 7-3/4" Curved Equalizers

Rough roads and uneven driveways can throw weight around between axles. The 7-3/4" long curved equalizers are built to pivot and distribute that load evenly as your trailer moves. They help both axles stay planted so the suspension works smoothly through bumps and dips, keeping everything balanced as it should be.

Reliable Mounting Across Tandem Axles: Complete Hardware Kit

Nothing slows a rebuild more than missing parts. This kit includes everything needed to hang your double-eye leaf springs to the frame—hangers, equalizers, shackle straps, bolts, and locknuts. The hardware ties the system together so the springs swing freely with no binding, giving you the consistent suspension action a tandem setup needs.

Tight, Secure Assembly Every Time: 9/16" Diameter Bolts and Locknuts

Loose hardware can throw a suspension out of line fast. Each of the fourteen 3" x 9/16" shackle bolts pairs with a matching locknut to keep the connection snug without over-tightening. Torque them until they seat, add a quarter turn, and the locknuts will hold fast while the springs move easily through their range.

Built for the Right Clearance: 3-1/2" to 3-3/4" Frame-to-Axle Gap

Keeping enough space between the frame and axle lets your suspension flex without bottoming out. This kit sets up a clearance of 3-1/2" or 3-3/4", depending on axle size, for proper travel under load. It’s designed for tandem, 2,000-lb to 7,000-lb axles, giving you dependable geometry and ride height across a wide range of builds.

Thank you for reaching back out. I have sent your information along to our customer service team.

They work excellent! The trailer is so much tighter.
When it is empty, you can't even feel it behind me. Except the noise from the ramps.
I also have to thank my buddy Rob, he put a lot of time and labor into getting the trailer in like new condition.
Sorry don't have photos at the moment.

Placed my order and received my items in good shape. One of the kits was missing and when I called to let them know they sent out the missing kit right away. Great customer service and the shipping was excellent and timely. Will definitely recommend to anyone that needs your services.



by:

My tandem axle equalizer kit, is of the highest quality. All the parts and hardware well made and will last for years to come. The combination of the knurled bolts and locking nut give me the piece of mind, that none of the hardware will back out and come off, on the highway. I would highly recommend this kit.

These were an exact replacement for my old trailer and have performed well the past year!

Bought and installed this rebuild kit on a 10 ft. horse trailer turned utility nearly a year ago. Trailer still pulls and rides like brand new after being abused almost daily.
Very pleased with the quality of parts included, and the detailed measurements given in the product descriptions. etrailer is where I will continue to look first for parts.

Hi George,
The trailer axel hanger kit

The trailer leaf spring kit was exactly the right fit for my trailer and has put us safely back on the road. etrailer helped me pick the right size and understand the options. What I received was a match for my need as my parts were completely trashed. This kit along with the bushings/sleeves made the repair quick and easy at a great price. I am glad that etrailer has knowledgeable folks available to talk through questions and take the guess work out of the purchase.

Easy to order, fast shipping

This was my first first order with etrailer and found them to be very good to work with. I had questions along the way which were handled expeditiously and resulted in ordering the right parts, which were a perfect fit with my old trailer. Product packaging was fine and the turnaround was fast.
If I was to offer a suggestion, it would be to include some instructions regarding proper lubrication techniques - location and type of lube they'd recommend.

Michael, you could lubricate the bushings if you want to with a multi-purpose grease, but the nylon bushings dont necessarily require lubrication, so there isnt a particular technique. We offer wet bolts that have a grease zerk on them to pump grease through, but other than that, the nylon bushings are designed to provide smooth operation until they wear down to a point where they should be replaced.

The parts I bought from you to repair the suspension on our livestocktrailer did the trick of getting it roadworthy. We dont use it often, butthe couple times weve had it on the road since the repairs have beenuneventful and thats a good thing when you have a couple tons of beef onit.

  • Limited Tire Clearance with Stock Tire Size on a 2006 Forest River Cherokee 27Q
    We recommend having a minimum of 3" between the top of the tire and bottom of the fender in order to allow for proper suspension travel. However, based on the photo you sent I believe you need new leaf springs as the ones you have appear to be almost completely flat. This has then compromised your tire clearance. The flattened leaf springs could either be a result of overloading the trailer or just general wear. In order to replace them you would need to know your axle capacity and the...

  • What Is The Purpose Of Steel band On Leaf Springs
    The leaf springs are normally installed with the band forward of the axle, but it is not something that has to be done that way. The steel band is called the rebound clip. Their main purpose is to help keep the main leaf from breaking on a rebound. When the weight of a vehicle or trailer is on the spring, all of the leaves work together to support the spring above them. If the wheel drops for any reason the total weight of the axle falls on the main leaf if there are no rebound clips....

  • Where to Place Axles on 14 Foot Long Tandem Axle
    To determine the location for the front and rear hangers on your tandem axle trailer you will first need to make sure that you have the correct center point for your equalizer hanger. The center point of your equalizer hanger needs to be located where you will have 60 percent of the frame of the trailer in front of the center of the equalizer hanger and 40 percent behind the center of the equalizer hanger. For example, if the trailers frames length is 14 feet, then the center-line location...

    I would love to help but are you sure that you have space to lower the trailer 4" - 6"? You will need at least 3" from the top of the tire to the bottom of the fender in order to allow for proper suspension travel. It looks like the fenders on the trailer now will not allow for this therefore I would you to do some measuring before any of the new parts are purchased. I would also need more info on the trailer such as axle capacity (see center label), leaf spring length (eye to eye), leaf...

  • Troubleshooting Trailer Suspension that Shackle and Equalizer Flip Over
    First thing you want to do is verify that you are using the correct dimensions for your hanger spacing on your trailer. The distance between the center hanger and either of the outside hangers should be right at 29-1/2 inches. There should be at least 3-1/2 inches from the center of the axle o the trailer frame. Also, you need to make sure your trailer is being towed level. If your trailer is nose high or low that can cause the suspension of a tandem axle trailer to be unbalanced. I attached...

  • Troubleshooting Broken Leaf Spring On a Boat Trailer With Tandem Axles Mounted Individually
    I recommend any trailer with a tandem axle setup use an equalizer regardless of the amount of leaves in the spring or if it is a double eye or slipper spring design. On a system like your trailer where each axle is mounted individually and not connected one axle will carry more of its share of the weight when one axle lowers due to road angles or unlevel trailer positioning. An equalizer setup like the Tandem-Axle Trailer Hanger Kit # APT3 will allow the suspension to continue to spread...

  • Why Do Trailer Hanger/Equalizer Kits all Use Different Height Suspension Hangers
    When the suspension hangers, equalizers, and shackles are installed from a kit like the part # APT3 the goal is to have the leaf spring as level as possible. The different height hangers is offset by the height of the equalizer and shackles so that when it's all said and down everything is at a level height. Check out the picture I attached of a kit like this installed to get an idea. The great thing about these kits is that the correct height of everything is already all worked out.

  • What Is The Difference Between Different Sized Hangers, Equalizers, And Shackle Straps
    Leaf spring hangers come in different heights to provide more or less clearance between the trailer body and the suspension. Manufacturers determine the best spacing for the axles and sizes of the hangers, leaf springs, equalizers, and shackle straps based on a number of factors to provide a stable base capable of handling the weight and any bumps in the road along the way. When replacing these components we always recommend matching the same dimensions to maintain the same suspension...

  • How To Determine Where Leaf Spring Hangers Should Be Placed
    The leaf spring hanger positions are largely dependent on which exact equalizers, exact leaf springs, and exact shackle straps you will be using as the length of these components is then what makes up the hanger positions. That said, I would not be able to provide exact distances with the information provided.

  • How to Decide Which Tandem Axle Trailer Hanger Kit to Use
    Typically when building a tandem axle trailer I recommend using either the # APT3 or # APT5 Tandem-Axle Trailer Hanger Kit. These are the most common kits used for utility trailers and parts are readily available. The # APT5 kit is by far the most common because all the hangers are the same height and provide good tire clearance. There are a lot of variables when selecting a hanger kit. First you should select a kit that will accommodate the wheel and tire combination you are using. The...

    Andy, while I do like your Axle # e95SR and U-Bolt Kit # CE23002 selection of which you will need 2 of each I do have another recommendation for the suspension kit. The Tandem-Axle Trailer Hanger Kit # APT3 you found has longer equalizers designed for a 35" spacing used on larger axles. Also I do not like the shackle straps it comes with either as they are a thin steel and over time the holes will likely start to elongate. Instead you should use the Dexter Heavy-Duty Suspension Kit # K71-359-00...

It does come with 9/16 inch diameter bolts.

  • 3,500 lb Leaf Springs and Hanger Kit Recommendation for a Mobile Home Trailer
    Mobile home axles/suspension are typically designed for one time use, so picking out components to work with mobile home components can be tricky. Your best bet is to do what you did with your axles and just start over with quality stuff that you will know will work. First let's start with a spring. For a 3,500 lb spring the part # e54SR would be a great choice. For a u-bolt kit you would want part # APUBR-1. For a tandem axle hanger kit you would want the part # APT3. For a bolt you would...

    Equalizer # TREQE1 does not have a weight capacity itself. It isn't bearing much of the weight compared to other components in a trailer suspension set up. If you have a tandem axle trailer then you could potentially use kit # APT5, # APT3, # APT9, # APT8, # APT7, or # APT3HD. All of these kits have the 7-3/4 inch long equalizers. For a triple axle trailer you could use # APTT5 or # APTT3. All of the above kits also come with hangers. If you do not need hangers then you would need to...

  • Hanger Spacing for 3,500 Pound Axle Leaf Spring # e59SR on Tandem Axle Trailer
    I think your idea is right on the money. Take the information from the 25-1/4 inch spring hanger spacing and subtract 2 inches. The subtraction will be 1 inch from the front hanger to the center hanger and another 1 inch from the center hanger to the rear hanger. Both of those measurements should be roughly 28-1/2 inches if using hanger kit # APT3. Using u-bolts for 3 inch diameter trailer axles is not a good idea on an axle that is 2-3/4 inches in diameter. It can allow for movement and...

  • What to Consider When Converting Single Axle Trailer to Tandem Axle
    You can convert a single axle trailer to a tandem axle but it's more extensive than just putting the extra axle on there. The current axle does need to be repositioned for proper tongue weight. You will also need to cut off the current hangers since the hanger spacing will not be the same. I've attached a chart that you can use to determine the axle placement. You'll need to the axle's weight capacity and diameter as well as the length and type of springs. Then we can determine exactly...

  • Hanger Spacing Recommendation for a Tandem Axle Trailer with 25-1/8 inch Long Leaf Springs
    For a 25-1/4 inch long spring like the part # e54SR you would want to go with 29-1/2 inches from the front to the center hanger and also 29-1/2 inches between the center and rear hanger. For a hanger kit we often recommend the part # APT3 which uses 2-5/8 inch long shackles that are pretty close to the length of your shackles.

  • Shackle Length Recommendation for Trailer Hanger Kit with 7-3/4 inch Equalizers
    The shorter shackle straps that measure 2-5/8 inches long like part # 115052GALV are typically used on dual or triple axle systems. The tandem axle hanger kit part # APT3 which includes 7-3/4 inch equalizers uses 2-5/8 inch shackles.

This kit will eliminate the need for welding new spring seats on top of the axle. I have included a link to a picture of what the new set up will look like.

    For your BBQ smoker trailer you are building, a single 5200 lb axle will work just fine. There are no requirements for single versus tandem axle applications. The biggest thing to consider is the stability of the trailer. I personally would be more comfortable grilling with the weight of the smoker over 3 contact points versus 2, so I recommend using the Dexter Trailer Axle w/ Electric Brakes # 35545E-ST-89 along with the Tandem-Axle Trailer Hanger Kit for Double-Eye Springs # APT3 and...

    There is not a specific torque spec for shackle bolts including the ones in the Tandem-Axle Trailer Hanger Kit part # APT3. They need to be secure but if they are too tight then the leaf springs will bind and cause problems in your trailer's suspension. The lock nuts included with the kit will ensure the bolts do not fall out. I recommend tightening the nuts until they makes contact with the shackle strap and then add another 1/4 turn. This should give you the right amount of torque needed...
