Received the package on Friday afternoon. Reviewed the instructions and postings @ E-Trailer. Pulled the trailer up in front of the house at 0930 Saturday morning and drove it away about 4pm. The biggest time killeer was as others have mentioned getting the 11,000 pound trailer up high enough and safe enough to do the job. Thanks for checking up on me. 135664

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

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

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

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

Review from a similar Dexter Trailer Springs Over-Under Conversion Kit


Kit arrived well packaged. Surprisingly quick to install on my 6x12 enclosed utility trailer. Using an air impact wrench to remove all the nuts from the old setup made for quick work. The instructions recommend removing one of the spring shackle bolts on both sides, but I found this unnecessary. I only removed the U bolts, then shifted the axle to the side until I could drop it under the spring, and then repeated on the other side. New U bolts and plates went on easily. I highly recommend this kit if the goal is added approach and departure clearance. Observations: 1) This kit raised the trailer 5 inches. Made a huge difference. 2) The instructions mention changing / adding bump stops to prevent spring damage from over-flexure. A little research points to 2.5 inches for maximum allowable axle travel, so I still have to source / fab ~4 inch tall bump stops (would be nice to have this all orderable from etrailer) 3) I am going to have the new spring seats welded to the axle tube as recommended, but only because I run brakes on this trailer and want to make sure the seats could handle the added torque of emergency braking. 88832

Review from a similar Dexter Trailer Springs Over-Under Conversion Kit


It took me 1.5 hours from start to finish, including clean-up, to install this kit. The instructions were simple and easy to follow, but remove the old u-bolts, plates and nuts - reassemble immediately for a reference of how the new bolts and plates go on (just upside down instead). I got a 5" lift as a result of using this kit. Currently, I am only using the nuts and spacing bolts but plan on getting the spring seats welded at some point. etrailer.com delivered them quickly, with great communication throughout the process. 55600

Review from a similar Dexter Trailer Springs Over-Under Conversion Kit


Got the parts I needed very fast, came as described. Was surprised to see the manufacturer as Dexter, the same manufacturer of my axle. The only thing I would add to the part is back up nuts where the extension nuts contact the welded on axle bracket to keep the extension nuts from working loose due to road vibration. I did not have to disconnect the brake wires from the brakes, I just unbolted each spring and place the axle under the spring and re-attached the spring to its perch. Took 4 hours to complete, great product. 153807

Review from a similar Dexter Trailer Springs Over-Under Conversion Kit


The product was great, the instructions were a little sketchy. Just one illustration would have made things a lot clearer. The instructions assume you know what each part is called but there is not even a list of parts included to help you figure it out. The results were just what I needed, though, about a 5" lift and my travel trailer no longer drags when coming up the drive. Word to the wise: go on and order a couple of extra shackle bolts and nylon bushings. It's cheap insurance and chances are you'll need them. 82401

Simple and easy. The worst part was the spider webs and black widows I found under my trailer. Took my time and double checked my work at each step.

This kit is well made and easy to use. The project itself is not for the faint-hearted, but this kit makes it about as easy as possible. The only reason I don't rate it excellent is that the instructions aren't the best. It's pretty straightforward to figure out on your own, but there was a bit of headscratching to start off. 117347

Josh, how did you get a four inch lift? The pictures of the kit doesnt seem like it would be that high?

comment by: Joe - 03/28/2013

It depends, in part, the thickness of his springs. The springs, if 2 inches thick and the pin point, would yield over a 4 inch with a 2-3/8 diameter axle.

Expert Answers about Dexter Trailer Springs Over-Under Conversion Kit - K71-385-00Do you have a question about this Accessories and Parts?


  • 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...

This is assuming that your axle tube is 3 inches diameter. If your axle tube is smaller the height will be sightly less. The curve of the springs you select will have some affect also. I would recommend that you go with the APT5 hanger kit because all of the hangers are the same height and it will make it easier to...

  • How to Determine the Capacity of Trailer Leaf Springs and How to Raise the Coupler Height
  • Leaf springs typically have the part # stamped on the strap that holds the leafs together at one end of the shorter leafs, or it is painted on the concave side of the springs. The part number can then be used to determine the capacity of the springs. Generally springs with any age on them will be very hard to get a part number off of. You would then need to go by the axle capacity to determine the spring capacity, which would be 1/2 of the axle capacity. If you have a 3,500 lb capacity...

If the axles are 3 inches in diameter, part # K71-385-00 would be a good choice. If you are thinking about lifting your trailer because your tow vehicle hitch...

  • 5th Wheel Trailer Rides High In Front Even with Hitch Set Low and Pin Box Set High
  • Since you have already adjusted the hitch and the pin box on the trailer, there is one other thing you can try. If the leaf springs are mounted below the axle(s) on the trailer, you can use an over-under conversion kit, # K71-385-00 for 3 inch diameter round axles or # K71-384-00 for 2-3/8 inch diameter round axles. What this will do is raise the back of the trailer up some giving you a more level ride. Since the ride height will change, the ride may be affected and the trailer will...

  • 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.

  • Raising Suspension of 2008 Keystone Outback 25RSS
  • The Dexter E-Z Flex Heavy Duty Rubber Suspension System you referenced, part # K71-652-00 replaces your existing equalizer like part # TREQ104. The rubber spring will isolate road shock and improve the ride of your trailer, but it will not raise the height of your trailer. If your leaf springs are currently connected to the underside of your axle, you can use an Over-Under Conversion Kit like part # K71-384-00 for a 2-3/8 inch diameter axle or # K71-385-00 for a 3 inch diameter axle...

  • Will Using Longer Suspension Hangers Make a Trailer Ride Higher
  • The hanger length can affect the trailer height. You would need to change the height of all the hangers equally to keep the geometry of the trailer the same. But at the end of the day there are other ways to get more height on a trailer. Keep in mind that increasing trailer height changes the center of gravity on the trailer and can also change the tongue weight and lead to sway problems. If the springs on your trailer are currently mounted under the axle, you can use an over-under conversion...

  • Dexter Trailer Spring Over-Under Conversion Kit
  • For a trailer with a 3,200 GVW, you most likely have a 3,500 lb axle, which is typically 2-3/8 inches in diameter. If this is the case, you would want to use part # K71-384-00. The Over-Under Conversion Kit you referenced is designed for 3 inch diameter axles, which typically have a 5,200 or 6,000 lb capacity.

  • Axle Flip Kit Recommendation for a 1995 Jayco Tent Trailer

If you have 2-3/8 inch axles you would want the Over Under Kit # K71-384-00.

  • How to Raise the Height of a 5th Wheel Trailer to Tow it Level
  • First, you will want to put the axle back to its original position. Trailer axles should not be flipped because doing so reduces the capacity and puts more stress on the suspension and tires, bearings and hubs. Trailer axles have a box in them that goes up in the middle of the axle. When weight is applied the axle flattens out. This is part of what gives the axle its capacity. When flipped the bow faces the wrong direction so you are losing that support. We do have over/under conversion...

  • How to Increase Ride Height of Fifth Wheel for More Clearance Above Truck Bed Side Rails
  • I'm assuming that you mean that when you drop the Goosebox by 2-3 inches it will raise the front height of the trailer, leaving it a bit high in the front. You want to raise the rear of the trailer so the underside of the loft won't hit the bed sides at the rear of the truck, is that correct? If the leaf springs for your camper are UNDER the axle, and your axle is 2-3/8 or 3 inches in diameter, you can use an Over-Under kit, like # K71-384-00 for a 2-3/8 axle or # K71-385-00 for a 3...

  • 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....
