Video of Dexter Trailer Springs Over-Under Conversion Kit
Videos are provided As a guide only. Refer To manufacturer
installation instructions And specs For complete information.
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

Haven't installed yet but looks good in the box and I know anything from dexter is good stuff so I'm not sweating it.... 116030
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
Shipped same day as ordered. Great price, fit perfect. will order again 146537

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
Great do-it-yourself kit. Worth the mon ey. 130056

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

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
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

The price & quality of this kit is unbeatable. When faced with the option of gaining more ground clearance got my trailer I had two choices - fabricating my own or buying this. It's a no-brainier. Thanks again etrailer! 61239
Great product. Used it to lift our 1992 camper travel trailer. The kit was easy to use and gave me about 5 inches of lift by moving my axles from the top of the leaf springs to the bottom of leaf springs. 209194

Would like to see a way to install the OEM shocks back into place the old spring plates has the holes in them and are just a littel wider to make this hapen 86348
I have a 99 cummins with 35s and a 5 inch lift. My 5th wheel now sits level and I even raised the king pin up another hole. I'd definitely buy this again 252516

Product very easy to install. Took three hours with a helper and that included getting the trailer blocked up and secure. Product is very strong. 105958
