Working great, dont worry about the suspension, everything is working perfectly.



by:

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.



by:

Purchased this item before. Great price and wonderful shipping. Will purchase from Etrailer in near future.



by:

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.



by:

fit great no problems, seems to be a good quality product, will be able to tell in 10 K miles



by:

Hi George,
The trailer axel hanger kit
that I purchased from you folks worked great!
The bushings were shot in the old ones and the new kit installed easily and solved the problem. Trailer tows like a dream. I will do business with you again if I need parts!
Thank You

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.



by:

Fast dependable quality parts



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.



by:

Came in good shape and was what I order ed



by:

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

They are still performing but are very rusty. I should have put my own paint on them to prolong their life.



by:

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.



by:

I bought a shackle kit for my car trailer and everything fit absolutely perfect. Super easy to install. I would buy another if I ever need one.



by:

The diagram that is shown below has incorrect dimensions. After all the hangers were mocked up as the given dimensions show the axle center to center distance was 29" not 30". I actually over looked double checking the center to center measurement and had to cut the center and back hangers off and will be moving them.



by:

Would rate negative if possible. Ordered parts for 4 day delivery found out that parts were delivered to another State and it would take 8 business days for the inquiry to be processed then another week for original package or new one to be sent out. To top it off a refund would also take the same time period. etrailer has put my company in a tough spot without these parts or a refund while claiming that’s the best they can do.



by:

Re did my pontoon trailer and it is nice to know they are good for another 30 years of service.

  • 2 inch Tall Hanger Kit with 5-3/4 inch Long Equalizers
    The closest kit we have to what you are looking for is the part # K71-359-00 which is for 1-3/4 inch wide leaf springs, has equalizers that are 5-3/4 inches long bolt center to bolt center, has 2 inch tall hangers, but it has shackles that are a little shorter at 2-1/4 inch and has bronze bushings. It does come with 9/16 inch diameter bolts.

  • Recommended Parts For Suspension Building Car Hauler Suspension With Tandem 3,500LB Axles
    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...

  • 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...

  • Double Eye Leaf Springs and Tandem Axle Hanger Kit Recommendation for a Boat Trailer
    There are two common types of trailer leaf springs. The slipper springs that you normally see with higher capacities, and the double-eyed spring that you see on more standard capacity trailers. They both work just as fine as the other when properly rated for the trailer. Due to the construction and fewer moving parts you commonly see the slipper on the higher rated setups, but not always. You can replace your current slipper springs with double-eye springs if you wanted to, but it might...

  • 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 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...

  • Does Trailer Suspension 7-3/4 Inch Equalizer EQ-E1 Have a Weight Capacity
    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...

  • 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...

  • Hanger Spacing Recommendation for Tandem Axle with Leaf Springs SP-222275
    The hanger spacing you'd need to use is 29-1/8 inches with the leaf spring part # SP-222275 with a tandem hanger kit like part # APT3. The height difference would be an inch.

  • What is the Torque Spec Rating for 9/16 Inch Diameter Shackle Bolts
    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...

  • 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.

  • 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.

  • Axle Hanger Measurements For Hanger Kit APT3 With Leaf Springs SP-113275
    To attach the Tandem-Axle Trailer Hanger Kit for Double-Eye Springs # APT3 with the 3-Leaf Double-Eye Spring for 2,000-lb Trailer Axles # SP-113275 on your trailer the hangers will be welded at the following measurements. You want the center of the front and rear hangers to be 27-7/8" from the center of the center hanger. This will put your axle center at 33-1/8" between the front and rear axles. Be sure that your center hanger is located at the correct point to give your trailer the...

  • Axle to Frame Height Difference Between Tandem Axle Hanger Kits # APT3 and # APT5
    We don't have CAD drawings we can give out for our hanger kits but I can help give you info to help you determine what the height of your axles relative to your trailer frame would be with each kit. With the part # APT5 it will give you approximately 4-1/2 inch to 5 inch of clearance and the part # APT3 will give you approximately 3-1/2 inch to 3-3/4 inch.

  • 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...

  • 89 inch Trailer Axle, 5 on 5 inch Bolt Pattern Hub and Leaf Spring Recommendation
    To get a 89 inch long axle you would want the part # T3584F-EZ-8974 for an axle that does not come with hubs and then for hubs you would want the part # 84556UC3 for a brake hub with a 5 on 5 inch bolt pattern or for an idler hub # 84550BX. Since this is a 3,500 lb axle you would want the same rated leaf springs. The # e54SR is a 3,500 lb spring that would work well for you. For a tandem axle hanger kit you would want the part # APT3 and for a u-bolt kit you would want the # APUBR-1.

  • 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.

    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...

    There is no one way to set up your spring hangars. It depends on the manufacturer on how they set them up.

We sell these as kits like theTandem-Axle Trailer Hanger Kit for Double-Eye Springs part # APT3 which I think matches yours from your description and also individually like the Front/Center/Rear Hanger for Double-Eye Springs part # E4139 allowing...

  • Where To Place the Leaf Spring Hangers On a Tandem Axle Trailer
    The leaf spring hanger positions are largely dependent on which equalizers and leaf springs you will be using. For example, if you were to use the Tandem-Axle Trailer Hanger Kit for Double-Eye Springs part # APT3 with the 5-Leaf Double-Eye Spring for 6,000-lb Trailer Axles part # e34SR. The front and rear leaf spring hanger would need to be placed 29-1/2" in front and behind the center leaf spring hanger. The center leaf spring hanger would then need to be placed in between the two axles....

  • Raising a Gooseneck Trailer with Tandem Axles for More Clearance
    If your springs are currently under the axles on your trailer, you can use what is called an over under conversion kit, # K71-385-00. This kit will allow you to move the springs to the top of the axle. For tandem axles, you would need 2 kits. They only fit 3 inch diameter axles. 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. When lifting the trailer even just a few inches, it...

  • Leaf Spring and Hanger Kit Recommendation for Trailer with 3,500 lb Axles to Lower Height
    Since all of the 3,500 lb axle leaf springs are longer than what you have currently which would mean you'd have to move your hangers your best option would be a hanger kit that's a little lower than what you have to lower the trailer like you want. The most common 3,500 lb axle spring is the part # e54SR which measures 25-1/8 inches in length. The # APT3 sits the lowest of all of the kits so it would be your best choice to use to replace what you have currently. Also it's not recommended...
