After buying a new truck I discovered that my 5th wheel was going to be too low to pull level. after doing some research I found your product which was what I was looking for. I ordered it and in 2 days it was delivered . Every thing went well in installing . The only problem I encountered was the plates did not contain a place to mount my shocks, after doing a little modifying I was able to use my old plates on top of the new ones and mount my shocks. Perhaps you could provide a plate that would have the hole for shocks.107458

Received the lift kit in good time. Installed on my dual axle 5th wheel camper in a day. Once the camper was elevated enough to remove wheels and room for the 5" of drop the kit was easy to install. Did weld the top bracket to the axle tube as suggested in the instructions. Nice product.94506

Etrailer has my business for any trailer part I need. When I purchased my over under conversion kit for my camper I was expecting it to be delivered in about a week. 3 days later a etrailer box arrived at my door! The part fit like a glove and is great quality. When a business sells Dexter parts they deserve good business! Thanks etrailer! 68269

Just what I needed. Very easy to install. We spent more time figuring out how to get the camper high enough to get the wheels back on then we did actually installing the flip kit. The super fast shipping and great customer support is what put etrailer.com on the top of my list. This is my second order but not my last. Keep up the good work!75764

  • Parts Needed to Move Trailer leaf Springs to Top of Axle on a Zinger ZT19RD Travel Trailer
  • To lift your trailer leaf springs from the bottom of your axle to the top of your axle to provide lift for the suspension you will need 4 new spring seats, 8 u-bolts, 16 nuts and 4 U-Bolt plates, see links. This is assuming that your trailer suspension is in good condition otherwise. The diameter of your trailer axles will determine the size of these parts that you will need to order. If your axles are 3 inches diameter, the kit you referenced, # K71-385-00, would be a great choice. I have

This is assuming that your trailer suspension is in good condition otherwise. If your springs are worn 2 new springs will be needed also, see link.

  • Why The Axles Cannot Be Rotated and Original Spring Seats Be Reused When Flipping Trailer Axles
  • The reason you will not want to rotate the axle and just reuse the spring seat is because there is a bow to the axles that flattens out as the weight of the trailer is applied to the axle that if you rotated the axle, the bow would flip and the alignment of the trailer tires would be way off and you would encounter problems with how the tires wear and with overall trailer handling. This is why the Dexter Trailer Springs Over-Under Conversion Kit # K71-385-00 that you referenced includes an ad

  • How Much Will the Dexter Trailer Springs Over-Under Conversion Kit, # K71-385-00 Raise the Trailer
  • First, you would need to have the spring seats welded to the top of the axle. You cannot flip the axle because then the existing spring seats would be bent the wrong way. What you can do is measure from where the springs are attached to the spring seat now up to the top of the axle to determine the approximate amount it will raise the trailer when using the Dexter Trailer Springs Over-Under Conversion Kit, # K71-385-00. To use this kit you will need to have a 3 inch diameter axle. When liftin

  • Can a Gooseneck Horse Trailer Be Raised to Avoid Making Contact with 1997 Dodge Ram 2500
  • I have a couple of possible solutions for you. First, though, you should check to make sure all of the suspension components are in good working order and replace any damaged or worn parts. If the axle on the trailer is a 3 inch round axle and the spring seats are currently mounted to the bottom of the axle, using the Dexter Over-Under conversion kit, # K71-385-00, that you have referenced will provide a few more inches of height. But this will also change the center of gravity of the traile

  • Compatibility of Dexter Over-Under Conversion Kit # K71-385-00 with Fifth Wheel Camper
  • The Over-Under Conversion Kit you mentioned, part # K71-385-00 is compatible with a 3 inch diameter axle, and would work fine with a fifth wheel camper. For two axles, you would need two kits. Keep in mind that in raising the trailer, you will be changing the center of gravity and will be making the trailer more top-heavy. By raising the trailer, you might also need to adjust he height of your fifth wheel hitch and pin box if they are adjustable.

  • Why Axles Cannot Be Rotated when Installing a Axle Over-Under Kit
  • In order to properly move your axle below your leaf springs you will not flip the axle. The reason for this is because there is a bow to the axle that if was reversed would give you terrible wheel alignment. What you would need to do is install the Dexter Trailer Springs Over-Under Conversion Kit # K71-385-00 you referenced. This allows you to keep your axles installed correctly while allowing them to be under your leaf springs. You will need to have new spring seats welded to the top of t

  • How to Choose the Correct Over-Under Axle Conversion Kit for a 1983 Palomino Pony Pop Up Camper
  • The diameter of the axle on your 1983 Palomino Pony camper will determine the correct over-under conversion kit that you will need. The Dexter Over-Under Conversion Kit, # K71-385-00, that you referenced will fit a 3 inch diameter trailer axle. We also have an over-under kit for 2-3/8 inch axles as part # K71-384-00. These are bolt-on kits that do not require you to weld the spring seat to the top of the axle, but the manufacturer strongly recommends tacking the new spring seat to the axle.

  • Raising Trailer Height Using an Over-Under Conversion Kit
  • First you are going to want to determine why the trailer is sagging at the back. Replace in worn suspension parts because you do not want to make any changes until the suspension is in good working order. An over-under conversion kit like # K71-385-00 would be the best way to go. This kit fits 3 inch round axles. We also have # K71-384-00 that fits 2-3/8 inch diameter round axles. The new spring seats are positioned on the top of the axle and the springs will then sit on top.

  • Dexter Trailer Springs Over-Under Conversion Kit Recommendation for Additional Ground Clearance
  • Yes, you can use a Dexter Trailer Springs Over-Under Conversion Kit # K71-385-00 like you referenced to gain a little ground clearance. This product will allow you to move the axles of your trailer from above the leaf springs to below the leaf springs which will give you additional ground clearance. As long as you have a 3 inch round axle this product would work well for you. 3 inch axles are primarily used on 6,000 lb and 7,200 lb axles.

  • Preventing Fifth Wheel Camper From Dragging When Entering Driveway
  • Since the axle is already mounted below the springs, an over-under conversion kit like the # K71-385-00 would not be helpful. Going with taller spring hangers (see link) might be an option, however keep in mind that changing the suspension geometry of your fifth wheel trailer might alter its ride characteristics and make it more prone to trailer sway. Additionally, changing the height might reduce the clearance between the top of your truck bed side rails and the bottom of your trailer loft.

  • Does Dexter Trailer Springs Over-Under Kit, Part # K71-385-00, Fit Haulmark 18-Ft Tandem Trailer
  • Haulmark produces a number of different 18-foot tandem axle trailers. This kit is applicable only to trailers with leaf springs and should be installed only if the suspension overall is in good working order. One kit is required per axle. Please note we offer this kit for 3-inch axles and also another kit, part # K71-384-00, for 2-3/8 inch axles. Typically, 2-3/8 inch axle diameter is a 3500 lb rating; and 3 inch axle diameter is typically a 6000 to 7200 lb weight rating. You will want to co

  • Raising the Height of a Carry On Utility Trailer with 1-3/4 Inch 2,000 Pound Axle
  • We only have over-under kits for 3 inch and 2-3/8 inch axles but nothing for a 1-3/4 inch axle. What you could do is get longer hangers. However, because suspension is meant to travel up and down adding hangers that are 2 inches longer for example does not mean you get 2 inches more height. Keep in mind that by increasing the height of the trailer you make it more susceptible to sway since the center of gravity is changing. If you need more height because the ball mount is too high then the b

  • Options for Adjusting Trailer Height on a Gooseneck Livestock Trailer
  • Mounting your axle under your leaf springs will lift your trailer more than 7 inches (4 inches for your axle diameter plus 3 inches for the thickness of your leaf springs and spring seat). Since you have a livestock trailer, that would not be the best option to level out your trailer. The first step that I would take is to check the coupler on your gooseneck trailer. Most gooseneck trailers have adjustable couplers that allow you to adjust the height of the trailer at the gooseneck hitch. If

  • Installation of Dexter Kit # K71-385-00
  • I have checked the installation instructions for the Dexter Trailer Springs Over-Under Conversion Kit # K71-385-00, and according to Dexter they strongly recommend tack welding the spring seats in place. Please note that this kit is intended for use with a 3 inch diameter axle and one kit is required per axle. If you have a 2-3/8 inch diameter axle then the # K71-384-00 kit is recommended.

  • How to Tow a Trailer Level Using a Ford Super Duty with a 6 Inch Lift
  • If you need the trailer to be higher to be able to tow the trailer level because of the lift on your truck then there is a much easier and safer solution than changing the suspension on the trailer. You just need a ball mount with the correct drop to tow the trailer level. I have included a link to an FAQ article that explains how you will need to measure. Once you know what drop you need you can browse our selection of ball mounts. I have included a link to them for you. I do not recommen

  • Tips on Leveling a 5th Wheel Trailer Towed by a 2012 Chevy Silverado Dually
  • First, before changing the suspension on the trailer, you can adjust the height of the pin box on the trailer and the height of the 5th wheel hitch up and down. If making these adjustments is not enough then I recommend moving on to an over under conversion kit like # K71-385-00. Using a kit like this does raise the trailer however it also makes the trailer more susceptible to sway. The ride will also feel different although in a dually I am not sure how much you will notice the ride. But if

  • Will an Over-Under Conversion Kit Fit a Trailer with a Square Axle
  • The over under conversion kits like # K71-385-00 only work on round axles. What you can do depends on why you need to raise the trailer. If you need more clearance under the trailer you can replace the leaf spring hangers with longer ones. You have to increase the height equally for all hangers. For example if you go up 2 inches on the front hanger, all hangers must also go up 2 inches. Raising the height of the trailer can change the ride quality and will make the center of gravity higher le

  • How Should a Flat Bed Gooseneck Trailer Be Pulled When Empty on a Flat Bed Truck
  • Even when the flat bed trailer is empty it still needs to be kept level. When the trailer is level it will have even weight on each of the tires therefore not wearing them more than necessary. As a side note, when you leave your gooseneck trailer high in the front it can cause some sway issues. Sway is not as big of an issue with gooseneck trailer, however, it is something to keep in mind. If your trailer is level when it is loaded and the issue that you are having is the nose is high when

  • Will Over-Under Conversion Kit Give More Wheel Well Clearance on 20 ft Prowler Enclosed Trailer
  • The Dexter Trailer Springs Over-Under Conversion Kit, part # K71-385-00, you referenced is designed to be used with double-eye springs, and 3 inch axles. If you have a 2-3/8 inch diameter axle on your trailer, then the Over-Under Kit you should use is part # K71-384-00. When installed, you should see more clearance in the wheel well of your 20 ft Prowler. The amount of increased clearance you will have will depend on the load in your trailer.
