• 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...

• 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),...

• 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.

• 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...

• 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,...

• Can Tandem Axle Spring Hanger Spacing Be Increased to 30-1/4-Inches to Fit Larger 235/80R16 Tires
  For your 3-inch axles the normal spacing of the hangers included in the DexterTandem-Axle Trailer Hanger Kit is 29-1/2-inches. You can probably space them the 3/4-inches further apart, to a spacing of 30-1/4-inches, without too much impact on the suspension geometry. However, you may be able to compensate for this change by using longer shackle straps. The shackle straps supplied with the kit are part # 115052 which are 2-5/8-inches long. We offer part # TRSL313 from TruRyde. We...

• 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...

• 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...

• 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 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....

  We have a kit that uses equalizers that are 6-1/4 inches in length. For that you would want part # APT4. This leaf-spring mounting kit includes 3-1/4" tall front hangers, 5-7/16" tall center hangers, 3-1/4" tall rear hangers and necessary hardware.

• 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.

• 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...

• 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.

• 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...

• 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 # SP-111275....

• 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...

• Will Equalizer of Trailer Suspension Tilt When There's Elevation Change on Trailer
  As long as they are level when the trailer is level you are probably fine. The equalizers are designed to pivot and equalize the load of the trailer on the axles when there's an elevation change so what you decribed is very normal.

• 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.

• How to Pick Out Replacement Suspension Components for a Trailer
  I tried looking up info for Tahoe trailers made in 2001 but since there were several different models made in that year of various sizes and weights I won't be able to give you a specific answer. I was able to determine that you do have a tandem axle setup on your trailer since all of the trailers they offer are tandem. First you will want to pick out the correct leaf springs. To do that you will need to know the length of your leaf springs as well as the axle capacity. Try to measure...

• 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...

• Are 10 Inch Trailer Wheels Compatible with Electric Brakes for Tandem Axle Trailer Build?
  The Kenda 205/65-10 Bias Trailer Tire with 10" Galvanized Wheel - 5 on 4-1/2 - Load Range E # AM3H490 is rated for a maximum load of 1650 lbs at 90 psi, so 3,300 lbs per axle. It however is only compatible with 7 inch brake assemblies and we do not have any axles that have that brake flange until you move up to 3,500 lb axles and then your brake hubs that fit those spindles will only work with 12 inch wheels or larger and 10 inch brake hubs.

• 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...

• 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.

• 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...

• 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.
