  • Can Trailer with Slipper Springs be Changed to Double Eye without Changing Hangers
  • You can swap to a double eye leaf spring setup on your trailer but you will need to basically remove and reinstall new hangers that were designed for this type of setup like with the # APT3HD. There MIGHT be a way to modify what you have but it's pretty hard to say what that would take and how well it would hold up.

  • Breaking In Replacement 6,000 lbs Leaf Springs
  • Thanks for the picture of your build sheet! It does look like the etrailer 6-Leaf Double-Eye Spring item # e94SR you purchased is the correct replacement spring. Feel free to email me back a picture of your suspension but unless you are flipping your equalizer with your trailer fully loaded you should just need to break the springs in. They're brand new so you should expect them to be pretty stiff especially if your trailer isn't fully loaded. I recommend checking to see if your new shackles...

  • Is It Required to Change Install Hardware When Replacing Trailer Leaf Springs
  • It really just comes down to the condition of the hardware Stephen. It's not one of those things where if you are replacing one thing you HAVE to also replace other things at the same time. If your shackle bolts, etc. are all in good shape then I would just leave them be when you install the springs # e34SR.

  • Replacement Leaf Spring Solution for 2021 Grand Design Solitude
  • The Dexter axles you have are 7k rated based on the part number you mentioned so the etrailer leaf springs part # e64SR that you referenced would be the correct part number as long as your current springs are right at 25 inches unloaded. If you have a different length we wouldn't be able to help though as this is our only option John.

  • Lift Kit Options For A 2004 Keystone Cougar 5th Wheel Trailer
  • Hey Cody, We do offer replacement suspension components but to increase your trailer's height you'll want to go with an over-under conversion kit like Dexter's # K71-384-00 (2-3/8" diameter axles) or # K71-385-00 (3" diameter axles). You'll need to first measure the diameter of your axle tubes and check if you're suspension underslung or overslung. You'll need an underslung suspension in order to use these kits. These are designed to "flip" the leaf springs to the top of the axle (overslung)...

  • Replacement Spring Hanger for a Tandem Axle Trailer
  • It sounds like you broke your rear spring hanger. Yes there are plenty of replacements, however you'll need to go over to the opposite side of your trailer and measure the one that isn't broken. You'll need to measure the height of the center of the bolt hole to the bottom of the frame. The Front/Center/Rear Hanger for Double-Eye Springs item # E4139 you were looking at measures 4-1/4" tall. I have linked our entire selection below for tandem axle trailers. Please feel free to email directly...

  • Parts to Update Suspensions on 2007 Venture Triple Axle Boat Trailer
  • The Dexter Heavy-Duty Suspension Kit # K71-359-00 you looked at would be a great solution for a replacement. You will need a quantity of two since you have a triple axle trailer. You will also have a couple spare bolts leftover should you need them in the future. I would piece a kit together to eliminate the extra but the equalizers aren't available separately. It comes with the heavy duty equalizers with grease zerks, wet bolts, and heavy duty shackle straps. You could also go with an...

  • SumoSprings Recommendation Kit to Replace OEM Bump Stops on a 2023 Jayco Jay flight 184 Baja Camper
  • Hey Blake, thanks for reaching out and providing all of the details and photos! The SumoSprings Trailer Helper Springs w/ Line Relocation Bracket # TSS-107-40 is an excellent alternative to the OEM bump stops that came on your 2023 Jayco Jay flight 184 Baja. From the photos you sent in I don't think you'll need to mess with any lines, but this kit still comes with a relocation bracket if you end up needing it.

  • Recommended Replacement Axle and Brakes for An Axis Products 93" Trailer Axle
  • Hey Eddie, I do have an option for you but the closest axle we offer for what you're looking for is the Trailer Axle Beam with Easy Grease Spindles # e93GR which measures 94" at the hub face and 79" at the spring center. Since this'll be used to replace a trailer axle with a 93" hub face, the wheels/tires are going to stick out a 1/2" more on each side At this point, the spring seats can then be cut and rewelded. To convert your presumably surge brakes to electric, you're going to need...

  • Will Anything Bad Happen if Too Big of Trailer Suspension Equalizer is Used
  • Your equalizers not sitting level is a sign that they aren't going to work as well since the movement they normally allow will be limited. It may not be a problem in the near future but basically components of the suspension will wear out quicker and your tires may wear out quicker as well. It would be best to replace what you have with the correct size equalizer like the part # TREQ356.

  • Troubleshooting Equalizer and Shackle Not Making W Shape After Leveling Trailer
  • Is this with it still leveled? Have you tried sitting it down completely on the axles again? That will likely get everything back into place. It doesn't look like anything is specifically broken/damaged from what I can see unless your leaf spring suffered damage but that isn't in the picture. The equalizers shifting like this can happen when leveling or lifting the trailer. Sometimes mine get this way and if nothing else driving gets it to shift back.

  • Is There An Air Bag Kit For a 2019 Ram 3500 Cab and Chassis Model?
  • The only air bag kit we have for your 2019 Ram 3500 cab and chassis is the Firestone Ride-Rite Air Helper Springs # F2478 which mounts above the leaf springs on the frame rail. I do not see any kits that will replace the factory jounce bumper. I do not see any reason these would not fit your application but you can verify based on the install instructions linked near the bottom of the page. The Firestone Air Command Heavy Duty Air Compressor # F96VV will allow you to adjust the pressure...

  • Upgraded Equalizers for 2024 Alliance Delta 251BH
  • Thank you for providing that information. It sounds like you already know this, but you want to choose a replacement equalizer that closely matches the one that came with the trailer. Since you have an 8" measurement on your standard equalizers I recommend the MORryde Shock Absorbing Suspension Equalizers # MR27ZR. These have the same 8" measurement between the outer shackle bolt holes with a height of 3-1/2". In addition to upgrading the equalizer I also recommend adding heavy duty shackles...

  • Lower Blue Ox Weight Distribution Spring Arms for 600 lbs - 700 lbs Tongue Weight
  • Hey Alan, thanks for reaching out! If you have the SwayPro system then you're using the 1,000 lbs TW Spring Bars # BXW4007 with a range of 750 lbs - 1,000 lbs, and if you have the 2-Point Sway system then you're using the 1,200 lbs TW Spring Bars # BLU64XR with a range of 800 lbs - 1,200 lbs.
