Bought a used car trailer in need of repair, sand blasted and painted the trailer. While working on it more and more things needed to be replaced. This hanger kit was a great match. Thank you etrailer.

Rec'd item quickly along with new wheels I purchased. Items were packed very well. I installed my new wheels, tires, and equalizer kit the following weekend and my trailer was ready to go.

I received the product and installed it on my dump trailer. Parts fit perfectly and were as described on your site.

The kit was a direct replacement no issues with the installation

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.

Comments
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.

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



by:

Came in good shape and was what I order ed



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:

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:

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:

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



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:

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:

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:

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

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

Fast efficient service, delivery and co st.

Seems to be quality stuff, Installed it and seems to work well. I will be a repeat customer due to the customer service, which has to be the best of any online retailer!! Thanks again etrailer I will be back as I do lots of hauling and my trailers require frequent maintenance.



by:

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



by:

Excellent customer service - they followed up with a phone call to let me know the order had been shipped and email kept me informed of the shipping process throughout. The parts I ordered arrived earlier than expected and were exactly as described - and for a fair pricie. Will order from this company again.

  • 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.

  • 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.

  • Trailer Suspension Kit Recommendation for Tandem Trailer Similar to APT5 but With 4.25 inch Hangers
    Since we don't have the exact kit you need you'd have to piece the kit together that you need. For hangers you'd want the pat # E4139 which is 4-1/4 inches tall like you mentioned needing. For 2-1/4 inch long shackle straps you'd then want the part # 18-11GALV. For the equalizers # TREQE1. And then for bolts # 126B2.

  • 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. 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....

  • How To Determine Axle Placement On Single Axle Trailer Being Converted To Tandem Axle
    Not necessarily. You will want to follow the included link to a helpful article that goes over proper placement of tandem axles. In short you will want the front axle in a location that makes the tongue weight 10-15% of the trailer weight. It may take a few tries to get the correct location.

  • Hanger Kit, U-Bolt Kit and Spring Seats for Tandem Axle Trailer with 3-1/2 Inch Diameter Round Axles
    A 3-1/2 inch diameter round axle is usually rated at 8,000 pounds but could also be a 3,500 pound axle though this is rare. You can get a more accurate determination of the capacity by getting the inner and outer bearing numbers stamped into the sides of the bearings. For a hanger kit # APT3 will keep the distance from the deck to the axles at a minimum and still have room for suspension travel. You will also need a u-bolt kit, # APUBR-35, for one axle. And you will likely need new spring...

    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.

  • 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...

  • Recommended Spring Hanger Kit for Load Rite Boat Trailer 3X5 Box Frame, 7200 lbs Gross Suspension
    There are a lot of variables to consider when selecting a hanger kit. First you should select a kit that will accommodate the wheel and tire combination you are using. The # APT3 kit is a good choice for smaller wheel and tire combinations like 14 inch wheel and tire combinations and the # APT5 kit would be a good choice for 15 or 16 inch wheel and tire combinations since it provides a bit more clearance for tire height. The # APT7, # APT8 and # APT9 hanger kits are typically used as replacement...

  • 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...

  • Tandem Axle Hanger Kit Recommendation For Car Hauler Trailer With 3,500LB Tandem Axles
    The only difference is going to be the height difference for the Hanger Kits # APT3 & # APT5. Since this is going to be for a car hauler the shorter hangers # APT3 will help to make loading low ground clearance vehicles easier since the trailer will be lower to the ground. Then you will be able to connect your two 3,500lb axles to the 4 Leaf Springs # e57SR using two U-Bolt Kits # CE23002

  • Why Is Trailer Suspension Shackle Angled and Not Totally Vertical
    You'll want the shackle hanging at a slight angle so that it doesn't want to flip upside down at any point. If it's totally vertical it will want to flip over much easier. Adding an axle certainly could be done while still using the old axle. It would be a matter of getting a tandem hanger kit like part # APT3 with the new axle.

  • Recommended Components Needed To Add Axles And Brakes To Tandem Trailer
    The first thing to consider is what the trailer is to be used for. If it is a boat trailer then electric brakes would not be the way to go, as water and electric do not work well together. I will make recommendations with the options you listed you want. Our 3,500 lb axles have the spring seats at 74 inches. If it is not a boat trailer the axle I recommend is the Dexter Trailer Axle w/ Electric Brakes, part # 35545E-ST-89. This axle measures 89 inches and includes the Includes electric...

    Yes, the Tandem-Axle Trailer Hanger Kit # APT3 would work great on a tandem axle with 3,500 lb axles. For leaf springs with a 3,500 lb rating that this kit is designed to work with you would want the part # e54SR.

    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...

  • 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....

  • 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.

  • 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.

  • 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...

  • 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...

The Tandem-Axle Trailer Hanger Kit for Double-Eye Springs also comes with the 2-5/8" Long Shackle Strap part # 115052 which measures 2-5/8" long from the center of each hole and 3/16" thick.

  • Replacement Leaf Springs and Hanger Kit for Jayco 312FKS Camper
    3 in diameter axles are typically 6k to 7.2k axles. 3,500 lb axles are normally 2-3/8 inches which you may want to remeasure to be certain on. For a 6k leaf spring that is 25-1/8 inches (which would be correct considering old springs stretch), we have the part # SP221275. For an equalizer kit with hangers we have # APT3.

  • 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.
