• Recommended Tandem Axle Hanger Kit For Double Eye Springs
  
• If you use the 5-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 25-1/4" Long # SP-111275 which have the same capacity, I recommend the Tandem-Axle Trailer Hanger Kit for Double-Eye Springs - 3-1/4" Front/Rear/Center # APT5 for a tandem axle application. When you follow the attached photo, this will give you the 33-1/2 inch axle spread. For your 6-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 26" Long # SP-053275, you can use the same system but replace the equalizers with...

• Changing 3,500 Pound Trailer Axles to 5,200 Pound Axles
  
• The first thing to consider is if the axle(s) are actually bent. Trailer axles have a bow in them so they are higher at the center than at the ends. When under load the axles straighten out some. That is part of how they get their capacities. If the axles are bent from damage then that is another story. Like you said the 5,200 pound axles that we have include spring seats that are on the bottoms of the axles. In order to have the spring stacks on top of the axles all you would need...

• Tandem Axle Hanger Spacing for Double Eye Springs 25-1/2 Inches
  
• For your double eye springs that are 25-1/2 inches, it is likely your hangers are 29-1/2 inches apart on center and your springs most likely were originally 25-1/4 inches as they will stretch slightly over time. For instance if you were to use 25-1/4 inch springs like # SP-111275 then you could use tandem axle trailer hanger kit # APT5 and use either spacing 29-1/2 inches on center for a good fit.

• How to Find the Correct Replacement Equalizer
  
• The Tandem-Axle Trailer Hanger Kit for Double Eye Springs # APT5 may have the correct equalizer but you will need to measure the current equalizer to find out. The length from the center of the left-most eye to the center of the right-most eye of your equalizer needs to be the same as the 7-3/4 inch measurement in this kit. Since you said the shackles are hitting the frame I recommend using a kit with a center hanger that is longer than the 3-3/4 inch hanger that comes with Kit # APT5....

• Recommended Axles for Two Trailer Builds with 14K Capacity & 7K Capacity
  
• For your trailers, I recommend not using a steering axle because there are different requirements for them and your trailers don't need them. If you want to pursue the steering axle you will need to check with your local DMV for requirements. My recommendation is to use a single or tandem axle application for each trailer. If you want to use a single axle for your 7K trailer, I recommend the Timbren Axle-Less Trailer Suspension System - Spindle w/ Brake Flange - Regular Tires - 7K...

• Trailer Suspension Kit and Leaf Springs Recommendation for a Tandem Axle Boat Trailer 4,600 lbs
  
• As long as you are replacing everything (hangers, springs, hardware, equalizer), then yes, you can use our trailer suspension kit, # APT5. In fact, this is the kit that I recommend for your trailer. The hangers must be welded to the trailer. The holes that you see in the top of the hangers are actually for welding, not bolt holes. For the leaf springs, you will be much happier with the ride quality of part # SP-212275 for 3,500 lb axles. The other springs you referenced are for 5,000...

• Recommended Tandem Axle Suspension Kit for Converting to Double Eye Leaf Springs
  
• The appropriate vertical height of double-eye leaf spring equalizers and hangers mostly depends on the axle diameter. 2K axles typically have a diameter of 1-3/4-inches. If you were to use a tandem axle kit such as # APT5 which has hangers that are 3-3/4-inches tall and equalizers that match well you'll be all set. It looks like you have just enough room to install this kit, as shown in the linked diagram. You will have about 5-inches of clearance between the trailer frame and the axle...

• Recommended Replacement Leaf Springs and Hanger Kit for 8,000 Pound Dual Axle Car Hauler
  
• Starting with the leaf springs, I recommend the 3-Leaf Double-Eye Spring # SP-220275. This 3-spring stack measures 25-1/4 inches from the center of spring eye to the center of spring eye. This is a more common spring length for this capacity, so it will be much easier to find an exact replacement down the line when needed. You can then use the Tandem-Axle Trailer Hanger Kit # APT5.. This kit includes 6 hangers, 2 equalizers, 8 shackle straps, 14 shackle bolts, and 14 locknuts. You will...

• What Causes Shackle Straps To Flip Below the Equalizer
  
• It is not uncommon for the shackle straps to flip once weight is lifted off the suspension but if they do so when you have a load bearing then this will not allow for proper load distribution or suspension travel. The cause of this issue is that the leaf springs are too long, the shack straps are too long, or a combination of both. The best option for you to make sure you get the proper spacing would be to change these parts out. If you can let me know the distance between your leaf spring...

• Spacing Measurements for Tandem-Axle Trailer Hanger Kit APT5 & Spring SP-051275
  
• When setting up a new trailer suspension it is best to do a mock-up (by clamping or tack welding the parts in place) to allow you to see how the system functions. There are so many variables that is best to test. Typical spacing dimensions for 25-1/8-inch springs are shown in the chart on the page for # APT5. Since the springs you intend to use, 4-Leaf Double-Eye Spring # SP-051275, are 7/8-inch longer than those listed in the chart, you will want to increase the hanger spacing approximately...

• 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...

• Placement of Suspension When Adding Hangers
  
• If making a trailer what you need to do is mock up the locations of all suspension components before setting anything because the tongue weight is going to determine the location of your axle, and therefore, your hangers. If you look at the help article I've added on positioning trailer axles there are equations you can use which will help you determine the distances. Without knowing more information such as the hanger kit you are using I would be unable to tell you the locations you...

• Suspension Hanger Locations for Dual Axle Dump Trailer
  
• There are some measurements missing that are important in giving you the exact positioning. I've attached a couple articles to assist with the dimensions you must calculate to get your precise 35 inch on center axles. Your center hanger will be obviously directly centered between the two axles and then your other two hangers will be spaced identically on each side. Your spring from the center of the outside hanger to spring seat location is the dimension that would be extremely helpful....

• 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...

• What is Minimum Distance Require between Tandem Trailer Tires When Considering Increasing Tire Size
  
• The difference in tire diameter will be an additional 2-1/2 inches going from the 225/75-15 which measure 28.4 to the 235/80-16 which measure 30.9 inches. As a general rule of thumb the minimum safe distance between front and rear tires on the same side of a tandem axle trailer is 4 inches. You would need to measure the distance between your tires currently and subtract 2-1/2 inches. If that dimension then ends up being 4 inches or greater the axle placement could be left alone.

• How to Determine Hanger Spacing for Tandem Axle Trailer Suspension with 26 Inch Springs
  
• Thank you for providing the specs for the suspension components that you already have. Correct hanger spacing really depends on the components being used such as springs, hangers and equalizers. Most of the hanger spacing dimensions that we have are based on our preassembled kits, so we will use that as a foundation for your setup. First, I would either replace all of the front and rear hangers with 2-1/2 inch tall hangers like part # 115918 or replace just the center hangers with 2-1/2...

• What is Ideal Distance Between Suspension Hangers and Equalizer Bolt Centers
  
• I'd need to know what the length of your leaf springs are be able to figure out the proper hanger dimensions. What you'll want to do is go with the distance between the hangers that allows the distance between the equalizer side bolt center and the outside hangers to be right near 1/2 inch longer than the distance between the bolt centers of the leaf spring to ensure you get the correct shackle angle.

• 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....

• Availability of 7k Leaf Spring and 5 Spoke Utility Hub for Dexter 7.2k Axle
  
• We have leaf springs that will work for you, the PR6 is a 24-7/8 inch 7k rated double eye leaf spring. Then for a hanger kit that comes with equalizers, hangers and hardware you would want the part # APT5. The hub you mentioned is our part # 8-174-5UC3. This comes with bearings. For easy lube caps though you would need the part # RG04-080. I wish we had the axles you are looking for, but we only carry a select few axles at this time and none of them have the dimension/capacity that...

• Ideal Leaf Spring Hanger Spacing for Tandem Axle Trailer Using # SP-111275 6000 lb Leaf Springs

If you have a 6000 lb 3 inch diameter axle, and you're using the # APT5 hanger kit which includes 7-3/4 inch equalizers and 2-5/8 inch shackle straps (which are the correct size for dual axle trailers, 3-1/8 inch shackles are usually used on single axle trailers) , the center to center distance between the front and center and center and rear hanger is 29-1/2 inches. The center to center axle...

• Replacement Parts for Karavan Classic Dual Axle Boat Trailer
  
• The axles on your Karavan dual axle boat trailer are likely rated for 3,500 pounds. You can verify this by checking the tag or plate on the axle which should list this information along with the part number and length. To pick out the correct leaf spring replacements, you will want to measure the length of the spring without any weight on it. I have attached a link that will take you to our available selection of leaf springs designed for 3,500 pound axles. If you cannot find a length...

• Determining Spring Hanger Spacing for Tandem Axle Trailer Fabrication Project
  
• Thank you for the measurements you provided and for the photo of your trailer suspension mockup showing the spring components' spacing. As long as your shackles do not hit the trailer frame (you mention 1/8-inch clearance) you should be fine, but if you'd like a bit more breathing room you could increase spacing from 29-1/2 to 30-inches without negatively affecting anything else.

• 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...

They are all 2-5/8 inches from center of hole to center of hole. If your current straps are different lengths, there are a couple of things to look at. The leaf springs may be different lengths, the hangers may not be positioned correctly, or the equalizer may be off-centered. Ideally you can the hangers, springs, equalizer and shackle straps...
