• Where to Install Shackle Straps and How to Determine Axle Position When Building an ATV Trailer
  For a 3,500 Dexter Straight axle the springs should be placed between 16 and 18 inches on center from the hub face (flat area the wheel mounts against). Placement of the spring centers in any other position will reduce the axle capacity. If you are using a different brand of axle you will need to contact the axle manufacturer for the full capacity spring center dimensions. If you are using double eye springs then the shackle straps will be located at the rear of the springs. The top bolt...

• Raising the Height of 5th Wheel Trailer to Tow it Level
  Sounds like the truck is too tall for your trailer. Your best bet is to lower the height of the hitch and/or raise the pin box on the trailer. Please note that raising the height of the trailer will increase the likelihood of trailer sway and can also reduce ride quality in general.

• What Axle Length Should be Picked to Match Width of Tow Vehicle Wheels with Trailer Wheels
  You will need to take the wheels off of your Jeep and measure from hub face to hub face. That dimension is the length of axle you should order for your trailer so that the sets of wheels from the trailer and vehicle will stick out the same distance. As long as the wheels you plan to install on the trailer have the same offset as the wheels of your jeep they will be the same width apart. It also sounds like this is an off-road trailer. Normally we recommend only ST rated trailer tire for...

• How to Determine Axle Position When Building Single Axle Utility Trailer
  The general rule when building a trailer is there should be a 60/40 percent split in weight when centering the axle. Sixty percent of the trailer weight should be placed forward of the axle for proper tongue weight. I can break this down for you. To determine the correct position for the axle determine the trailer weight under the wheels and the tongue weight. This will require a mock up (pre-build) of the trailer. Once these weights are determined you will need to add the two numbers...

• Why Do Trailer Leaf Springs with the Same Capacity have Different Lengths
  Trailer leaf springs come in many different lengths and some may have the same capacity but different measurements and/or number of leaves. This is due to different configurations of trailers, axle spacing, and tire size. Ideally you would use the same length springs that the trailer currently has. Over time, springs can flatten out some so the measurements of old springs can be slightly off of a new spring. Also when measuring an old spring you have to do so with no weight on it be either...

• Do Trailer Suspension Hangers have to Be Moved to Go with a Longer Axle
  If you wanted to go with a longer axle and not have to change the suspension hanger locations you would just need to order an axle with the length that you want and the same spring center to center dimension as your current axle. As long as the spring center to center dimension is the same the new axle will bolt right up. I attached a link to a page that has all of the axles we carry.

• Can Leaf Spring Hangers Be Installed Without Welding
  For strength and stability we always recommend welding the leaf spring hangers to your trailer. It would not be a good idea to use screws or any other type of hardware to secure the hangers due to the amount of stress they get during use. Another note of caution is that if the trailer you are welding the hangers to is galvanized, make certain this is done in a well ventilated area as the fumes produced from welding galvanized metal are toxic.

• Tips On Where to Place an Axle on a Trailer
  Well, that is going to depend on several factors. Roughly, very roughly, it would be 3/5 of the way back from the front. But there is more to it than that. There is a bunch of basic math involved. Like you wanted, I have included a picture that should help you determine where the axle should be placed on your trailer.

• How To Determine Where To Mount Your Axles On A Trailer Build
  The 60/40 rule of thumb method would have the center of the axle spaced at 8.4' (14' x 60%) from the center of the coupler. For tandem axle trailers this is where the equalizer would sit. The key is going to be setting the axles so that the tongue weight sits at 10-15% of the total trailer weight. I've attached a help article below going over how where to place the axle and the formulas needed to determine where to move the axle(s) if the tongue weight falls above or below 10-15%.

• Where to Measure From When Determining Axle Center on Trailer
  Sounds like you are trying to place the axle of your trailer so that you get 60 percent of the trailer in front and 40 percent to the rear. You would want to use the axle center as the dividing point for the frame dimensions. Ideally the 60/40 split is a starting point and from there you determine the tongue weight of the trailer in hopes of it being 10-15 percent of the total trailer weight. If so, then you are good to go. If not then you need to adjust the axle location.

• In What Orientation are Trailer Suspension Hangers Installed
  Based on the picture you submitted you would want to rotate the hanger that is in your hand 90 degrees clockwise and weld the flat portion with the 2 holes in it to the bottom of your trailer frame. So yes, you are correct in how you thought it should be welded on. I attached an FAQ article on trailer suspension for you to check out.

• Axle Placement Recommendation for a 72 Foot Long Trailer
  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 72 feet, then the center-line location...

• What is Total Weight When Using Axle Placement Formula
  The axle placement formula listed below will need to be calculated using the trailer's gross vehicle weight rating (GVWR). The gross vehicle weight rating (GVWR) is the most the trailer can weigh loaded. This will ensure that the trailer is setup to properly handle a full load. There should be an info tag on the trailer (near tongue) that lists the (GVWR) but if not you would need to contact the trailer manufacturer with your VIN.

• What Could Cause a Homemade Trailer to Sway
  When you are calculating the 40/60 split of weight on a trailer you are going to want to consider the entire length of the trailer. There could be a lot of reasons for trailer sway but your best defense against it is proper loading of the trailer. Heavier items should be at the bottom and the load should be even side to side. If the tongue weight is too low or too high, that could also cause sway. Typically, the tongue weight should be 10 to 15 percent of the gross trailer weight when...

• What is Minimum Trailer Axle to Frame Clearance for Leaf Spring Deflection
  Typical spring deflection is up to 1-1/2 inches when at capacity. The recommended clearance with leaf spring suspension on an unloaded trailer is between 2 - 2-1/2 inches. You should have sufficient clearance with your loaded trailer, as leaf springs only tend to deflect 1-1/2 inch when carrying a load.

• Should Trailer Leaf Spring Suspension have the Shackles Straps Angled or Totally Vertical
  If the shackles aren't angled slightly you run the risk of the equalizers angling and having the shackles on the wrong side of the springs. 28 inch leaf springs are hard to come by so your best solution will be to either go with replacement equalizers that are a bit longer than what you have or move the hangers in a bit closer. If you can get me the distance between the bolt hole centers of your current equalizers I can come up with your best option. In meantime I attached a link to all...

• Does A 3000lb Axle Need Leaf Springs With 3000lb Rating or 1500lb Rating?
  Leaf springs for a 3000lb axle will have a 1500lb rating each, and the combined rating of 3000lbs. With that said we do not offer any leaf springs with this rating, so the closest option is the 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles - 27" Long # SP-210275. These springs have a 1750lb rating each so they will be slightly heavier duty than your axle, but are still close enough that they will still work. These springs measure 27" from center of spring eye to center of spring...

• Where to Place Axle on a Custom Built Pontoon Boat Trailer
  When it comes to placing an axle on a trailer there is no set place for it to go, however the help article I have attached can really help you out in determining where the best place is on your trailer. A good starting point is having 60% of the trailer in front of the axle and 40% behind (include the tongue with this starting point) but because most of the weight of your boat will be at the rear due to the motor, you will most likely want to move it further back on the trailer in order...

• Where Is Measurement Taken On 1-1/2 Inch and 2 Inch Hangers In Redline Trailer Hanger Kit # APTT3
  The height measurement of the hangers in the Redline Triple-Axle Trailer Hanger Kit, part # APTT3, is from the top of the hanger to the center of the bolt hole. The 1-1/2 inch tall hanger is the Redline Front/Rear Hanger for Double-Eye Springs, part # 115917 and the 2-1/2 inch tall hanger is the Redline Center Hanger for Double-Eye Springs, part # 115918. I am including a picture of the hanger and it shows where the dimension is measured.

• How to Trailer Suspension Hangers Attach to a Trailer
  Suspension hangers for trailers like the part # 115917 need to be welded on. There are no options for bolt on hangers so your best option would be to have a qualified welder/fabricator move your current ones. The goal should be for axle place that when the trailer is loaded it would have 10-15 percent of the total weight of the trailer as tongue weight.

• Why Do Trailer Suspension Hangers Have Holes in the Top if they have to be Welded On
  The holes in the top of a trailer suspension hanger, such as # 115917, are there if the installer wants to do a button weld instead of welding around the outside of the hanger. Button welds are difficult to do just right but they would fill up the hole(s) with the welded metal to secure the hanger to the surface.

• Trailer Suspension Hanger 115917 is Too Wide to Use with Shackle Straps
  Hanger # 115917 can function as a rear hanger for a tandem or triple axle set up but it is too wide to be used as a rear hanger in a single axle application. Since you already have them you could use washers to equal out the width between the hanger and the spring. Or you could go with hanger # 93003-3X which is more narrow and thus would be a proper fit without washers.

• How to Determine Axle Placement on a Custom 5 x 9 ATV and Motorcycle Trailer
  When determining the axle placement on a trailer, an important factor to consider is the tongue weight. You want the tongue weight of the trailer to be approximately 10 percent of the gross trailer weight. Moving the axle rearward will increase the tongue weight of the trailer. A heavy tongue weight could cause issues with traction and sway when towing, but that is not as much of a concern on smaller trailers than it is on larger travel trailers or enclosed trailers. First, we want to...
