Video Transcript for Dexter Accessories and Parts K71-385-00 Review

Today we're going to be taking a look at the Dexter trailer springs over-under conversion kit. This conversion kit is designed to fit 3 inch diameter axles. It's going to allow you to move the the trailer loose springs to the top of the axle without having to change the correct orientation of the axle. This is going to help with leveling your trailer. It's going to help with wheel well clearance. It also adds some height to prevent dragging, dipping, and bottoming out.

One kit is going to come with enough components for one axle, so one kit per axle. This is designed for use with double eye springs only. The unit is going to include 2 spring seats. These are going to sit on top of your axle. It's going to come with 8 nuts. You're going to get 4 U bolts, 2 tie down plates.

The tie down plates are going to sit on top of your loose springs once you have them moved to the top of the axle. It does have all the holes in it, that way the U bolts can wrap around the axle and come up through the plate. Then, you would secure it by installing the included nuts. It's going to come with the spacer nuts. These are going to allow the set up to install level.

Basically, you would have 1 spring seat on top of the axle, then your old spring seat would still be under the axle. The spacer nut is going to fill the gap between the 2 spring seats, so they thread on to the bolts that are welded on to your new seats right here. Again, it's going to fill the gap between the 2 spring seats. You would place this on until it makes contact with the bottom spring seat. Then, what you would need to do, which is highly recommended from the manufacturer is you would tack weld this to the axle to prevent the axle from slipping.

Then, you can finish the tightening process or make any minimal adjustments simply by using a wrench. Everything that you see here on the table is included. It's going to come with detailed installation instructions as well to help walk you through the installation process step by step. It is a bot on installation with some recommended tack welding. Overall, it's a nice unit. We're looking at all steel components, so nice, strong, durable design. Again, this kit is designed to allow you to move the trailer loose springs to the top of the axle without having to change the correct orientation of the axle. Again, it's going to help level the trailer. It's going to help gain some extra wheel well clearance, and it's going to help add some clearance to prevent those situations where you may be dragging, dipping, or bottoming out. That's going to do it for today's look at the Dexter trailer springs over-under conversion kit.

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

Very happy with the product. Trailer toes so much better not that its level with my truck. The extra clearance helps a lot to when towing off-road to the remoter camp spots we like .

The husband used this to flip the axle on our fifth wheel. The fifth wheel was an older model (2007) and the king pin was too short to ride level with our 2014 3/4 ton truck (bed was too high) and I didn't want the truck lowered. It road nose high with the back end scraping on driveways and such. So the axle was flipped which raised the trailer about 4" overall. The trailer was perfectly level with the truck. There are you tube video's showing how this is done. The husband has had to tighten these three times this year (he checks it every time we take the trailer out). We could not find anyone to weld this on for us. And I don't weld, but whatever. It works without welding. Pictures aren't great but it gives you an idea how these have held up. 269201

Etrailer service great again, Repeat customer with this order and will continue to buy from them. I ordered my kits on-line early AM and they shipped out same day, delivered to me the next day. Kit goes together very easily. Especially if you just cut the old u-bolts off like I did. I had a couple hours doing my tandem axle car hauler. Only issue is neither kit I received had enough nuts in it, I only got 2 nuts in each box. The u-bolts are 1/2-20 Thread size (same as Older Ford Lug nut) if someone else has the same issue. I am sure etrailer would of made this right but I got it on my own. 216816

Good product, bought 2 identical sets. First set matched my existing axles perfectly. Second set the spring perches were 1/4 inch narrower, part numbers were identical, the leveling bolt was welded on crooked, making it unusable. Had to get new spring perches locally. I called, spoke to Madison, offered to have new ones sent. Needed trailer for this weekend. Overall happy with product, the bolts really do help get parallel to other perch. Excellent service from etrailer, fast shipping. Gained 7 inches on 3 inch 3500 pound axles. 204264

Product is of very good quality, it fit well and did exactly what it was supposed to do, well designed and fairly easy to install, I use my trailer more than most people do and I have been totally satisfied with the parts that I purchased, flipping the axles leveled the trailer right up & it pulls great 380202

Contacted Jennifer at 4 PM on a Wednesday informing her that I ordered the wrong size axle spring conversion kit. I asked if she could do her best to get it to me as soon as possible. Whatever she did, it was on my porch by 8 AM the next morning. Job Well Done. Will use again 458459

Kit arrived missing all but 2 of the ubolt nuts. No biggie, had some on hand. Went to install ubolts and they were too short. Bought new ones. Went to use top plate and it was too narrow. Had to make new ones. Only thing I used was the axle perches... Which you can buy anywhere. Total waste of money. Make your own kit like I ended up doing. 225292

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

This product looks good but I decided not to install it. It ended up that after installing the Reese 5th wheel hitch I had around 5 inches of clearance between my bed rails and the trailer and after lowering the trailer weight onto the hitch it wasn't too much out of level and I haven't had any trailer tail dragging. 239365

Product is well designed. The ability to install on a 3" axle without welding is a plus. 2 guys, a floor jack and 2 jack stands along with the proper tools and 2 hours to install complete. Left trailer attached to the truck and lifted the rear to make the conversion. What a breeze. 234865

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

If you find you've bought a trailer from someone and found you didn't look at it close enough before you bought it and find the axels are upside down, this is a great fix. Nice kit at a good price and fast shipping. Thanks etrailer. 347429

Works as advertised After all is said and done it is still recommended To tack weld the spring pad in place. This defeats 90% of the do-it-your self. Easier to remove axle and fit/weld new spring pads for perfect alignment. 306760

Would have given 5 stars except that one of the kits was provided with the wrong size nuts for the u bolts. Luckily, I was able to utilize a set of my origional u bolts which are better quality than what was provided with the kit. 252187

  • Trailer Suspension Hanger Kit with the Most Lift for Tire Clearance Under the Trailer Bed
  • The # APT4 Tandem-Axle Hanger Kit will provide about 4 inches of clearance from the center of the trailer axle to the bottom of the trailer frame, with no load on the axle. 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 Gain Ground Clearance for a Travel Trailer that Hits the Driveway When Entering or Leaving
  • There are a couple different ways to raise the ride height of your trailer, but before we choose the best option for you, we will want to take a look at a few things. First, it sounds like you are not towing with your trailer level so you do not hit your ball mount on the driveway. A trailer that is not level can create many problems such as ground clearance and trailer sway. If you have any sway control issues with your trailer, then I would recommend moving your leaf springs above...

  • 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...

  • Are There Lift Kits Available for Trailers
  • If you are talking about a lift kit for a trailer then they are called over/under kits. There are 2 options. First we have # K71-384-00 for 2-3/8 inch diameter round axles. And second we have # K71-385-00 for 3 inch diameter round axles. If neither will work then the other option to raise the height of the trailer is to use taller suspension hangers. I have included a link to our hanger main page for you. Current pricing for parts can be found on their respective product pages.

  • 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...

  • Recommendation For Spring Over Axle Conversion Kit To Use on Trailer With 3,500-Lb Axles
  • The typical axle diameter for an axle that is rated for 3,500-lbs is 2-3/8 inches. Some can have a 3-1/2 inch diameter, but it is very rare. I would recommend to use the Dexter Trailer Springs Over-Under Conversion Kit, part # K71-384-00, you have referenced, which is designed for the 3,500-lb axle with the 2-3/8 inch diameter. The Dexter Trailer Springs Over-Under Conversion Kit, part # K71-385-00, is designed for the 3-inch diameter axle that is used on 6,000-lb and 7,200-lb axles. I...

One or more of these suggestions might be required to achieve the proper clearance. If your truck is lifted or has larger than stock wheels/tires, returning the truck to stock ride height will solve the problem in most cases.

  • 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....

We usually tell customers that they need 5 or 6 inches from the tops of the bed sides to the bottom of a 5th wheel trailer overhang.

  • How to Raise a Trailer for More Ground Clearance
  • There are a couple of things that you can do to get more ground clearance for your new trailer. First, if the leaf spring stack is attached under the axle then you could use an over/under conversion kit. If the trailer has a 2-3/8 inch diameter round axle use # K71-384-00. If it has a 3 inch diameter round axle use # K71-385-00. This will move the leaf spring stack to the top of the axle and raise the trailer approximately the same amount as the axle diameter. These kits will only...

  • Raising the Height of a Travel Trailer that Rides Close to the Ground
  • If the leaf spring stack on your travel trailer is currently mounted to the bottom of the axle, there is an over-under conversion kit that you could use to gain a few more inches of height. However, this will change the center of gravity on the trailer and can lead to an increased chance of trailer sway. For 3 inch round axles you could use # K71-385-00. And for 2-3/8 inch round axles use # K71-384-00. You should not have to do any welding to use these kits. You would not want to...

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.

  • Recommended Over-Under Conversion Kit For Flipping Axle On Coleman Pop-Up Camper
  • We have two conversion kits we offer and they will work on either a 2-3/8 inch or 3 inch round axle only. If you have double eye springs, and the axle on your camper measures 2-3/8 inches then part # K71-384-00 would work for you. If you have a 3 inch axle on your camper, part # K71-385-00, would be the kit you need. These kits come with the spring seats, nuts, U-bolts, and tie plates. The spring seats will have to be welded to the axle when installing.

  • Ways to Even Out Different Heights of Lifted Truck and 5th Wheel Toy Hauler Trailer
  • A lifted truck usually brings with it some complications for towing purposes. A trailer axle over-under conversion can be a solution to correcting some of the variance in the heights of the tow vehicle and trailer, but this too comes at a high cost: raising your trailer's center of gravity. This higher center of gravity will tend to degrade trailer handling. Depending on the particulars of the trailer, the benefits of getting the trailer level when hitched could be completely voided by...

  • 5th Wheel Hitch With Maximum Height for Most Trailer-to-Truck Bed Rail Clearance
  • Thank you for the photo of your 2016 Ram 3500's bed rail which sits 59-inches above ground. You are correct that the recommended minimum clearance between a bed rail and the underside of the trailer's overhang is 5 to 6-inches, as shown in the linked diagram. Since your trailer sits lower than your truck you'll need some height adjustment to tow safely. By chance is your truck lifted? Lifted pickups are not ideal for 5th wheel towing for the reason you have already discovered. Even some...

Dexter has the following note on the conversion kits: When converting from underslung to overslung, the installation of bump stops to prevent suspension over travel and resulting possible spring damage or breakage is highly recommended. Axle travel should be limited to the amount available prior to mounting conversion. When converting from overslung to underslung,...

Depending on the amount of leaves on your leaf springs this should give you about a 4-6 inch lift. The diameter of your trailer axle will determine the size of the parts that you will need to order.

  • Lowering Height at Front of Fifth Wheel Trailer By Adjusting Pin Box
