• Can Trailer Weight Capacity Be Increased by Changing One Trailer Axle
  A trailer's weight carrying capacity depends on many components: the trailer frame itself, axles, suspension, hubs, wheels and tires. Upgrading one component, say an axle, might increase the trailer's capacity but only if that axle was the lowest-rated part of the trailer. It is not advisable to use two differently-rated axles on the same trailer. Strictly speaking, it is theoretically possible, IF the trailer were to be loaded up with the cargo load perfectly distributed across the two...

• Which Axle of Tandem Axle Trailer Typically is the Brake Axle
  Really it depends on which axle is carrying more of the weight. Typically the front axle is the braking axle for most utility trailer and campers but for boat trailers where the weight is more on the back it's typically the rear axle. We have also found that most torsion brake axles are the rear axles as well.

• How to Determine Where Axle Should be Placed on a Trailer
  There is a way to determine axle placement on a trailer. I have included a picture that explains the calculations needed to determine axle placement. It is based on tongue weight and gross trailer weight. If you know the combined axle capacity then the tongue weight should be 10 to 15 percent of that.

• Recommended Replacement 26 Inch Long Leaf Spring for Trailer Upgrading Axle to 4,000 Pounds
  If your eye diameter is 9/16 of an inch, then I recommend the Redline # e27SR leaf spring. I would double check the other measurements listed for this spring to ensure fit on your trailer, but this will work for your higher axle capacity and accommodate your 26 inch bolt hole to bolt hole spread. It's important to note that each spring carries 50 percent of the axle's weight rating. I have linked an image with the measurements as well as a help article and installation video for your...

• Choosing Replacement Double-Eye Leaf Springs for StartCraft Pop-Up Trailer
  You can change out your springs to higher-rated ones but that will not increase the trailer's weight carrying capacity. It will likely give you a stiffer ride, which you may or may not prefer. Chances are good that your trailer spring broke because it was 10-years old and brittle. You'll want to replace both springs to ensure the trailer tracks correctly. We do offer a 6-leaf 26-inch spring rated for 4500-lb axles, part # e27SR, but as you noted your springs have probably become elongated...

• Should Trailer Suspension Shackle Face Up and Down
  Sounds like one of your shackles is facing the wrong direction after installing everything. When a shackle flips around and faces the wrong direction on trailer suspension most of the time just putting weight on the trailer and driving will correct the problem. Or you can try jacking up one of the axles to get the equalizer to angle and allow the shackle to flip around.

• Troubleshooting Trailer Suspension to Reduce Porpoising
  It sounds like you have done everything possible on the tow vehicle side to reduce the up-and-down porpoising you noted, so I suggest checking out the trailer's suspension. Leaf springs do wear out and lose their weight-carrying capacity and this can lead to more motion from the overall system than with new springs. Also items like shackle straps can wear, their round holes becoming enlarged and/or egg-shaped. If many components in a trailer suspension are worn you can end up with excessive...

• Can Front and Rear Trailer Suspension Hangers be the Same Height with Off-Level Leaf Springs
  Front and rear suspension hangers are not often the same height like this but they can be. If you have the hanger spacing right then what will happen is the center of the spring will be offset a little between the two hangers to compensate some for the height difference from the hangers/shackle straps. The rear hanger will actually be closer to the front hanger than the rear spring eye so the shackles will be at an angle like in the drawing I have included. If this still does not get your...

• Why Would a Trailer Equalizer not Sit Horizontal at Rest on a Tandem Axle Trailer
  Most likely it means your ball mount has too much drop and that is angling the trailer so that there is more weight on the front axle. To determine what the correct rise/drop ball mount you should use is check out the FAQ I attached to the right.

• Suspension Components For Home Made Trailer
  In order to find the right leaf spring for your trailer you will need to know the weight capacity of the trailer axle. I have attached a link to our product page for the double-eye leaf springs we offer. The double-eye springs we offer range in length from 20-1/4 to 27 inches long, which is quite a bit shorter than the 36.5 inches you mentioned. If you are unable to find springs that are the length you need, you may need to replace the hangers you currently have. My recommendation is...

• How To Determine Proper Axle Placement On Single Axle Trailer
  Using a 60/40 ratio is a great place to start when deciding where to place your axle, placing 60 percent of the weight in front of the axle. However, there are a couple other factors that come into play. I have attached a photo that outlines that equation you will need. Mocking up the design will be the easiest way to determine the correct location of your axle. As a start, you will want to determine the approximate 60/40 location of your axle. For example, if your trailer is 84 inches...

• Replacement Leaf Springs for 16 Foot American Hauler Nighthawk
  To replace your trailer leaf springs, the best way to get an accurate measurement is to jack the trailer and measure the springs while the axle(s) are hanging. This is done because over time, the leaf springs can flatten. To get the proper length measurement, measure the center eye to center eye distance, see provided diagram. Assuming your trailer is a single axle, given its GVW of 7000 lbs, you'll need 3500 lb springs. I'll link you to our selection of 3500 lb leaf springs. Increasing...

• Measuring a Double-Eye Trailer Leaf Spring Length to Find a Replacement
  When measuring a trailer leaf spring it has to be done with no weight on the spring. You can do this by jacking up one side of the trailer and measuring the spring on that side. Or by removing a spring. It is likely that the springs on your trailer are shorter than 26 inches eye to eye. They also tend to flatten out some over time. I suspect that you actually need a 25-1/4 inch spring but measuring without the weight on the spring would be the way to determine what will fit. I have included...

• How to Measure a Trailer Leaf Spring
  To measure for the correct leaf spring length, you should jack up the trailer so that the axle hangs free, then measure straight across from the center of one eye to the center of the other eye. Because springs tend to flatten out as they wear, this the best way to get an accurate measurement. Each of our product pages for the leaf springs shows a diagram showing the width and height of the spring. If you click the provided links, you can see the double eye leaf springs we offer as well...

• Trailer Bottoming Out and Flatten Double Eye Leaf Springs
  The amount of leaves does not necessary indicate capacity so it is possible that the springs you are using are under rated for the trailer. There could also be other suspension components that will need to be replaced. Check for signs of obvious damage such as cracked or broken parts or egg-shaped holes. If you have two 3,800 pound axles and the trailer weighs 8,000 pounds then the trailer is overloaded by 400 pounds and that is likely causing the problem. Going to higher capacity springs...

• Center Spring Hanger Position for Tandem Axle Trailer that is 18 feet Long
  The 60/40 split is a great starting point that usually works for most trailers. This includes the length from the coupler to the back of the trailer. For example, if the trailers frames length is 18 feet, then the center-line location for the equalizer hanger will be 10.8 feet from the front of the trailer and 7.2 feet from the back. This is where to start with when picking out axle locations for a tandem axle trailer. You will need to determine the tongue weight of the trailer and then...

• How to Determine if Trailer Axle is Not Aligned and How to Measure to Replace Trailer Axle
  If the trailer wheels scrubbed (dragged and scrapped the ground instead of rolling) when jack knifed then it could have thrown something out of alignment or damaged something. First, inspect the suspension. Look for any elongated holes where suspension is bolted/hanging. Elongated holes can cause things to shift from the proper positions. You can check axle alignment by measuring from the center of the coupler back diagonally to the center of one of the wheels. Then take the same measurement...

• Troubleshooting Elongated Hanger Bolt Holes in Tandem Leaf Spring Suspension
  Sounds like you are experiencing a lot of movement in your suspension which is causing the elongation of the back hanger bolt holes. Over time this is going to happen with normal wear, but most likely the wider hangers and narrower springs are speeding up the process. Your best bet is to put in properly sized springs or properly sized hangers.

• Troubleshooting Trailer Leaf Springs That Have Broken Twice
  If all of the suspension components of the trailer are in good working order and it isn't being overloaded the springs shouldn't be breaking. How much does the trailer weigh total? Are the roads you are traveling rougher than most? What weight rating springs did you go with after breaking the 3,500 lb ones? Typically a broken leaf spring is from an overloaded trailer, I would verify that your trailer and it's cargo weigh less than the rating for the springs and also check the other suspension...

• Will Shackle Bolts for Leaf Spring Need to Be Retorqued After So Many Miles
  When leaf springs like the 6-Leaf Double-Eye Spring, # e27SR, are installed with locknuts and shackle bolts that are torqued properly, you should not have a problem with the bolts backing out. Of course, checking on them every so often wouldn't hurt anything.
