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

Easy way to get more ground clearance for things like mounted jacks. Easy to install. Good product. Raised my travel.trailer 5 1/2". Enough to stop the rear from dragging. 86965

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

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 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

Very quick and self explanatory to install. No need for instructions mounts very solid and gave me a 4.5" lift it looks awesome and now I will be able to go anywhere I want. Will definitely use this product again when I upgrade to another RV. 137819

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...

  • 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...

  • Raising Height of 5th Wheel Suspension to Provide Proper Clearance Between Bed Sides and Trailer
  • There are a few things you can try to get the proper 6 inch clearance between the top of the bed sides and the bottom of the fifth wheel trailer loft. 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. Adjusting the fifth wheel hitch so that it is at its highest level and moving the pin box so that it is at its...

  • 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....

  • 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...

  • 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.

  • 5th Wheel Hitch Installation on Lifted Short Bed 2014 Ram 2500 Without Factory Rail Kit
  • Let's start with a 5th wheel hitch for your truck. For a short box truck like your 6-foot-bed 2014 Ram 2500 you'll need a sliding 5th wheel. I recommend a round tube slider with the greatest amount of slider travel to give you the most turning clearance. Demco's 18K slider # DM8550034 offers 14-inches of travel and works with their custom base rail install kit # DM8552025-71. For a 5th wheel wiring harness use part # PK11893-11932.

  • Truck with 4-wheel drive tend to be taller than there 2-wheel drive brethren and add to that the fact that truck manufacturers make the bed sides taller and taller every generation and its no wonder clearance can be an issue! 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.

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.

  • 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...

  • 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...

  • 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...

  • 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 Raise the Height of a Boat Trailer to Avoid Scraping on Inclines
  • What I recommend, if the trailer has round axles, is an over-under conversion kit. For 3 inch round axles use # K71-385-00 and for 2-3/8 inch round axles use # K71-384-00. This of course will only work if the leaf springs are mounted to the bottom of the trailer now. What this kit does is allow you to put the springs on top of he axle without flipping the axle or welding. Otherwise what you could do is use taller hangers. All of the hangers would have to be raised the same amount. So...

  • Can Trailer Height be Raised by Changing the Suspension
  • If the trailer leaf springs are currently mounted on the bottom of your axle, moving them to the top of the axle will lift the suspension. To do so you will need 4 new spring seats, 8 u-bolts, 16 nuts and 4 U-Bolt plates per axle. The diameter of your trailer axles will determine the size of the parts you will need to order. 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...

  • Over Under Axle Kit Availability for a Pop Up Camper Trailer
  • 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, would be a great choice and if your axle is 2-3/8 inch diameter you could use the Over-Under Kit, # K71-384-00. These kits can be installed without welding but the manufacturer strongly recommends having the new spring seat tacked in place on the other side of the trailer axle. Some refer...

  • How to Add a Lift to a Toy Hauler Trailer for Better Ground Clearance
  • You can lift your trailer by taking the axles of the trailer and moving them below the leaf springs. 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. If your axle is 3 inches diameter, the Dexter Trailer Springs Over-Under Conversion Kit, # K71-385-00, would be a great choice and if your axle is 2-3/8 inch diameter you could use the Over-Under...

  • Increasing 5th Wheel Ride Height by Installing Taller Equalizer
  • Changing your equalizer height by two inches will gain you a slight height increase, but because all the pieces of the suspension (springs and shackles) all move together, you will not get the full 2 inch height increase. The equalizer will be a bit taller, but most of the height difference will be taken up by the springs and shackles, because the height is not being changed at either end where the springs connect to the spring hangers. Your best bet would be to choose taller spring...

  • Lowering Height at Front of Fifth Wheel Trailer By Adjusting Pin Box
  • To drop the front of the pin box and thus lower the front of the fifth wheel, you'd need to RAISE the pin box, not lower it. Lowering the pin box would raise the height of the fifth wheel at the front. If you have an available set of holes at the top of the pin box turret, you can go that route. If you don't have an extra set of holes at the top of the pin box, there are a few other changes you can implement. If the leaf springs of your fifth wheel are installed so they're sitting on...

  • Moving Trailer Axle from Below Leaf Springs to Above the Leaf Springs
  • Yes, you can use the over/under conversion kit # K71-385-00 to move the axles to the tops of the leaf spring stacks. 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,...

  • Raising the Height of a 5th Wheel Trailer and Hitch to Avoid Bottoming Out on Steep Inclines
  • First, you could lower the pin box on the trailer to get some extra height at the front if you have already raised the hitch to the maximum height setting according to the instructions. But to raise the back of the trailer you will need to use what is called an over-under kit. We have 2 different kits and what they do is move the leaf springs from under the axle to above it (if they are already above it there is not much more you can safely do). The first kit, # K71-385-00, is designed...

  • Parts Needed to Do an Over-Under Kit on a 1-3/4 inch Trailer Axle
  • When you use an over under kit like the part # K71-385-00 you end up gaining a lift that measures the diameter of your axle, plus the spring seat, and the thickness of your leaf springs. You will need to measure those items on your trailer to determine the amount of lift you would need. Since we don't have a kit designed to fit a 1-3/4 inch diameter axle, and since you aren't completely sure that is the diameter of your axle you will need to verify this before I can piece you together...

  • Can a 5th Wheel Trailer be Towed with a Ford F-250 with an 8 Inch Suspension Lift
  • Possibly but it depends on how high we can get the trailer and what adjustments can be made to the hitch and pin box. First, a suspension lift makes the towing capacity of the truck unknown and actually lowers it if anything. Just keep this in mind. Measure from level ground to the truck bed and from level ground to the king pin skid plate to see what that height difference is. This will tell you how far off you will be to be able to tow the trailer and if it is possible to get level...

  • 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...
