Video Transcript for etrailer Trailer Suspension - Leaf Spring Suspension - APT3 Review

Today we're going to take a look at the Tandem Axle Trailer Hanger Kit for double eye springs. Now, this leaf spring mounting kit will include the four 1-1/2 inch tall front and rear hangers, the two 2-1/2 inch tall center hangers, and all the necessary hardware. Now, the equalizers themselves are 7-3/4 inches long which is measured center to center. Now, this will attach four leaf springs to your trailer frame. We do sell the leaf springs separately on our website, and to determine your hanger location on your trailer we have a table at the bottom of this product page, and we'll show you the measurements that are required based on the type of life springs you use. This part will achieve either a 3-1/2 inch or 3-3/4 inch clearance between the trailer frame and the axle depending on your axle size.

It includes all these parts right here. We're going to go through each one. The four 1-1/2 inch tall front and rear hangers, and the 1-1/2 inches is measured from the center of that hole to the top, so if we put a ruler on that there's your 1-1/2 inch measurement. It includes the two 2-1/2 inch tall center hangers, and it's measured the same way. Center the top is right at 2-1/2 inches tall. The equalizers, the curved equalizers, they are 7-3/4 inches long, and we mentioned they are measured from the center of one bolt hole to the center of the other.

There's your 7-3/4 inches, and they use 9/16 diameter end holes and center holes. Now, the shackles. There's eight 2-5/8 inch long shackle straps, and again they're measured center to center. If we go center to center there's the 2-5/8 inches, and then the remaining parts are the hardware. It comes with 14 3-inch long 9/16 diameter shackle bolts and 14 9/16 diameter lock nuts. Now, this is designed for use on trailers with tandem 2,000 pound up to 7,000 pound axles, and this does not include the components for mounting your axle to the springs. That should do it for the review on the Tandem Axle Trailer Hanger Kit for double eye springs..

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. 337848


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.

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


  • Recommended Parts For Dual Axle Trailer Complete Rebuild
  • For your trailer rebuild, I recommend the Dexter Trailer Axle w/ Electric Brakes - EZ-Lube - 5 on 4-1/2 Bolt Pattern - 89" - 3,500 lbs for your tandem axles, # 35545E-ST-EZ-89. You will also want the U-Bolt Kit for Mounting 3,500-lb, Round Trailer Axles - 5-1/2" Long U-Bolts, # APUBR-1. For suspension I suggest the 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles - 25-1/8" Long, # SP-212275. You will then need a kit with mounts for your equalizers and shackle straps.

  • Recommend Hanger Kit For A 3,500 Lb. Tandem Axle Car Hauler
  • If this was my personal trailer. I would first start with the trailer's axles. As you mentioned a need for 3,500 lbs axles, I recommend using the Dexter Trailer Axle w/ Electric Brakes part # 35545E-ST-EZ-89. In addition to the dual Dexter axles and 1-3/4" leaf springs like the 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles part # SP-212275, I reccomend going with the Tandem-Axle Trailer Hanger Kit for Double-Eye Springs part # APT5. I recommend going with this hanger kit as it will...

  • Leaf Spring and Hanger Kit Recommendation for Tandem Trailer with 5k Axles
  • Since you are looking to replace everything best thing is to go with a properly rated 5,000 lb per axle leaf spring like you need and then build the parts you need from there. So for a 5k rating 4-leaf spring we have the part # SP-218275 which is 25-1/4 inches long. This is a very common length. Then for a kit that includes new hangers, shackles, and equalizers we have the tandem suspension kit part # APT3 which would work well.

  • Hanger Spacing for 3,500 Pound Axle Leaf Spring # SP-216275 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...

  • Rebuilding a Tandem Axle Trailer with 6,000 Lb - 7,200 Lb Axles
  • 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),...

  • 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 # SP-111275. 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...

  • 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...

  • Tandem Axle Trailer Suspension Hanger Kit To Provide More Axle Clearance
  • 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...

  • 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.

  • 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...

  • 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....

  • 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,...

  • 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.

  • 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...

  • 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...

  • 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 # SP-212275 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. The Never...

  • 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.

  • Parts Needed to Rebuild Suspension and Axle Placement on Gooseneck Trailer
  • To start with, the 6,000 pound springs I suggest are # SP-111275. They're 25-1/4 inch long, 5 leaf springs. I recommend either hanger kit # APT3 or # APT5 with the springs. The difference between the two hanger kits is the height of the hangers. With either kit it's recommended to space the hangers 29-1/2 inches apart and the axles 33-1/2 inches apart. See the diagram I attached. You'll need to position the axles so that 10 percent of the trailer's total weight is on the tongue....

  • 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.

  • 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...
    view full answer...

  • 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 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...

  • 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.

  • 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...

  • Hanger Spacing Recommendation for a Tandem Axle Trailer with 25-1/4 inch Long Leaf Springs
  • For a 25-1/4 inch long spring like the part # SP-212275 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.

  • Picking Out Replacement Double Eye Springs for 1,720 lb Trailer
  • When replacing trailer leaf springs we strongly recommend you replace them in pairs. I would urge you to get a set of matching properly rated springs for your trailer as soon as possible. If you look on the frame of your trailer there should be a plate with the trailer VIN number and the axle capacities of the trailer. You will want to pick leaf springs that are as close to the axle capacity as possible. I attached a link to a page that has all of the 2k rated double-eye springs we carry...

  • Recommended Trailer Suspension And Axles Along With B&W Biker Bar For Motorcycle Trailer Build
  • Being a Harley guy myself, I understand your concern and appreciate your question on ride. The torsion axles won't necessarily give you a softer ride as a lot of the ride is dependent on the complete system. The torsion axles basically have the suspension integrated but are not adjustable. The leaf spring suspension gives you that adjustability and there are even suspension dampening equalizers available like the E-Z Flex Heavy Duty Rubber Suspension System by Dexter Axle - 5-5/8" Equalizers...

  • Recommended Trailer Axles and Suspension for BBQ-Smoker Trailer with Pit Weighing 3,000-3,500 lbs
  • 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-EZ-89 along with the Tandem-Axle Trailer Hanger Kit for Double-Eye Springs # APT3...
