• Replacement Leaf Spring with Single Leaf Compared to Multi-Leaf Spring
  The 1-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 25-1/4" Long # SP-115275 will have the same capacity strength as a multi-leaf spring. It will replace a spring of the same length with the 3,000 lb capacity so it will work for a 6,000 lb axle. The benefit of not having the multi-leaf springs is the thickness is different in that this leaf spring will only have a 7/8 inch thickness making it fit well with the U-bolt around your axle. This spring will work just as well as the...

• Ways to Raise the Suspension of a Trailer
  There are ways to raise a trailer's suspension, but moving the shackle straps so that they are underneath the equalizer would not be a recommended method. The most common way is to move the axles above the leaf springs if they are currently under them, or to get longer suspension hangers. The diameter of your trailer axle will determine the size of the parts that you will need to order. If your axle is 3 inches diameter, the Dexter Trailer Springs Over-Under Conversion Kit, # K71-385-00,...

• Determining Correct Shackle Strap Size for Top Brand Tandem Axle Trailer
  Trailer manufacturers don't usually keep a record of parts like these that they install at the factory, so I cannot be sure as to the exact length of the shackle strap that would have come originally on your trailer. With this in mind, a 3-1/8 inch long shackle like what you have is typically used on single-axle systems and would be a bit strange on a tandem axle trailer. The most common size for the type of trailer you have is a 2-5/8 inch shackle strap like # 115052. You will simply...

• Should Trailer Suspension Shackle Straps Mount Below or Above the Equalizer
  Having the shackles below the equalizer would put the leaf spring out of level. Also, the equalizer wouldn't want to function properly and most likely the shackle would end up flipping over to the top of it or binding up/putting undue stress on the leaf spring/shackle/equalizer. You would definitely want to have the shackles mounted above the equalizer. Check out the help article I attached on trailer suspension as well.

• Replacement Double-Eye Leaf Springs for DHM Boat Trailer
  We can help you with replacement double-eye trailer leaf springs. Do note that you always want to replace leaf springs in pairs. This is because a new spring will have a slightly different length (it will be a little shorter) than the old one; this is due to the normal elongation of the spring that happens from years of use. If you replace only one spring you can run into axle alignment issues that can affect trailer tracking and tire wear as you go down the road. Always replace both...

• Will Changing Leaf Springs Help Unloaded Ride Quality of a Trailer
  The problem is that in order for the trailer to have the overall capacity it needs to carry what the trailer is rated for it needs to have a very stiff spring. The trade-off is that when the trailer is loaded the springs are working fine, but when the trailer is unloaded it can be pretty annoying. If you were to go with a spring that is light enough so that the trailer would not bounce around as much the trailer would also no longer have the capacity it once did. So basically you...

• Replacement Trailer Leaf Spring Recommendation for Trailer with 26-1/2 inch long Springs
  Since trailer leaf springs tend to stretch out over time when you pick out a new one you want to go with one that measures just slightly shorter than what came off the trailer. Since yours is 26-1/2 inches a 26 inch long spring like the # SP-051275 would work well if you need a 4k rated leaf spring. If you need a different axle capacity you would need to check out the link I attached that has all of the 26 inch long springs we carry.

• Does Single-Leaf 6K Leaf Spring SP-115275 Have a Pilot Nub for U-Bolt Plate
  The Universal Group 1-Leaf Double-Eye Spring # SP-115275 does not have a center bolt as found on the comparably-rated 6K spring # SP-111275. That center bolt head, or pilot, is not present on the single leaf spring because it is not needed as it is with multi-leaf springs. You can still install this spring using a u-bolt plate that has a center hole. Although these two springs share the same dimensions and weight capacity (25-1/4 x 1-3/4, and 6K) if you are replacing a multi-leaf spring...

• Hanger Kit Recommendation for a 6K Axle on a Tandem Trailer
  There are two spring options that would work for you, the part # SP-115275 that you referenced or the 5 Leaf Spring part # SP-111275. The only difference is that the # SP-111275 is a multi-leaf spring with a 100 lbs more capacity than the # SP-115275. Either would work fine for you, I would go with the # SP-111275 just because of the additional capacity, and with a multi-leaf spring if a leaf fails your trailer wouldn't be completely un-usable. You would be able to limp home to fix the...

• Recommended Replacement 2-Inch-Wide Leaf Spring on Old Utility Trailer
  Thank you for providing the detailed description of your broken 4-leaf spring. If the spring is 2-inches wide as you state then it is likely to be a single-eye slipper-type spring such as those shown on the included link. If the spring has an eye on both ends then it is a double-eye spring whose width is probably 1-3/4-inches rather than 2-inches. We do not offer any double-eye leaf springs in the 2-inch width (although rare they do exist). We offer only a 1-3/4-inch width as those shown...

• How to Determine the Correct Leaf Springs and Parts for Suspension 1956 Shasta Camper
  To determine the correct parts you need to replace the springs on your trailer you will need to do some measuring and find the GVRW, Gross Vehicle Weight Rating, of your trailer.

• Trailer Hanger Kit Recommendation for Trailer with 25-/4 inch long Leaf Springs
  Mobile home axle components can be hard to find replacement parts for, but if you have leaf springs part # SP-115275 the part # APT9 would be a great hanger kit to use. The distance on center between the spring hanger bolt holes for dual axle setups, with the # APT9 Tandem-Axle Trailer Hanger Kit, should be 29-1/2 inches for double eye springs that measure 25-1/4 inches on center between the spring eyes and for axles that are 3 inches in diameter.

• How to Measure a Trailer Leaf Spring to Pick Out Correct Replacement
  If you are trying to measure your current leaf springs so that you can pick out the correct replacement ones you will want to measure from the center of the eye to the center of the other eye. Typically springs will flatten out over time (around 1/2 inch), so you will want to pick a spring that is slightly shorter than what your current spring is. The amount of leaves isn't as important as picking out one the correct length and capacity. I attached a help article on trailer suspension...

• How to Move Axles Under Leaf Springs on a Horse Trailer with Slipper Springs
  Dexter Trailer Springs Over-Under Conversion Kit, like part # K71-385-00, is specified by Dexter for use only with double-eye springs. It is not suitable for use with slipper springs. If you really wanted to move the axle under the leaf spring you would have to replace all hangers, equalizers, and springs. The part # K71-385-00 is the correct over under kit for 3 inch axles like yours so that's a good start. 3 inch axles are typically 6k or 7.2k axles so for leaf springs the...

• Leaf Spring Replacement Recommendation for a Trailer with 6000 lb Axles
  The Double-Eye Spring # SP-115275 that you referenced would work well for you. I did a little research and found that with your distance of 29-1/2 inches the # SP-115275 would be the perfect length once you factor in the distance that the equalizers take up. These springs are also designed to work with 6,000 lb axles so this would be perfect for you.

• Leaf Spring Replacement For 26 Inch Measurement Eye to Eye With 4 Leafs
  For a set of leaf springs that would fit your trailer you would want the part # SP-115275. These are 25-1/4 inches from eye center to center which should work well as a replacement for your 26 inch long ones. Yes, sometimes it is good to allow for slight variations in this measurement because the springs can sag and elongate as a result of wear. These answers are based off of a trailer with a 6000 pound axle. If your axle has a different capacity let me know and I can make different...

• Is There Potential Problems by Placing Shackle Straps in Front of Axle Instead of Rear Axle
  As long as your shackle straps are not elongated, bent or rusted you can place them in front of your axle. It's always a good idea to check shackle straps frequently because they are the part that will wear the most. If you need to replace, you will measure the shackle from center of one eye to the center of the other eye. I included a helpful article and video review for you too.

• How To Measure Trailer Leaf Springs To Find Replacement
  You are not able to add a leaf to any of the existing springs you have to increase the capacity you want to carry. My recommendation is to install new springs to be able to handle the added weight. You will need to take some measurements to make sure you get the right system. You will want to measure the distance center-of-spring hole to center-of-spring hole. I have attached a photo that shows where the dimensions are taken for a leaf spring. You want to make sure the entire system...

• Does Center Pin Come with the 1-Leaf Double-Eye Spring for 6,000-lb Trailer Axles SP-115275
  There is no centering pin that comes with the 1-Leaf Double-Eye Spring for 6,000-lb Trailer Axles # SP-115275 but there is a "nib" that helps keep it centered in the spring seat. I'm not quite sure what you are referencing unless it is the bolt in the middle of a stack of leaf springs like part # SP-053275 which helps keep the leaf springs aligned. If you have something different please send me a picture of it so I can see if it is something that we carry.
