After my original coupler was damaged, I ordered this replacement. It was a perfect fit for the original. I had a welder come to my home and install it and I was on my way in an hour. Quick shipping by etrailer and just what I needed for my Jayco bunkhouse. 905953

My RV trailer stands really tall and in order to tow it level my hitch was so high that it interfered with my tailgate. By cutting the regular coupler off the top of the frame and welding this underslung coupler to the bottom of my 6" frame, I gained about 5" of space. This allowed me to move my hitch ball down while keeping the trailer level. I can now open my tailgate without hitting the hitch. 821207

Just fine. This was to upgrade and replace an older coupler. Weld on was very simple

  • Is There Thumb Latch Repair Kit for Underslung A-Frame Coupler
    There is not a repair kit for the thumb latch of the A-Frame Trailer Coupler - Underslung - Thumb Latch - Black - 2-5/16" Ball # CA-5335-B. While I wish we had an option for you, if yours has busted you will need to replace the entire coupler.

  • How to Measure the Angle of Trailer A Frame To Determine if a 50 Degree A Frame Coupler will Fit
    I would use a protractor, see photo, place the protractor on the edge of the inside of one side of the trailer frame and the other inside edge of the trailer frame should be parallel with the 50 degree line on the protractor. Another way to verify the angle is to measure the angle where the frame meets the cross member for the trailer bed itself. This angle should measure 65 degrees on each side, which will give you a 50 degree angle for the coupler. The standard dimension for trailer...

  • Hard to Release Undermount Trailer Coupler from Hitch Ball
    I don't think you are doing anything wrong apart from jumping on the truck and even that isn't wrong it's just more fun to jump on a trampoline or in puddles. There are several reasons why the coupler could be having a hard time releasing from the ball. First, if there is tension on the ball from the truck/trailer being on uneven ground then that could be the problem. Pulling slightly forward or rearward to release the tension may be all you need to do. You also might be able use...

  • Troubleshooting Movement Between Trailer Coupler and Hitch Ball On Weight Distribution System
    There will be some play with any ball and coupler because the trailer has to rotate. However, it sounds like you have too much movement because putting another hitch ball in place seemed to fit better. I recommend changing the hitch ball in your weight distribution system if it is no longer the correct size. If the coupler you have is an underslung coupler that may have something to do with the noise as well. We do have weight distribution systems that are specifically designed for...

  • What is the Hole Spacing to Mount a Jack to A-Frame Trailer Coupler CA-5335-B
    A-Frame coupler with jack hole # CA-5335-B has the industry standard mounting pattern which is 3 inches between holes on center for the back 2 holes and 2-7/8 inches apart on center from the front hole to either of the 2 back holes.

  • What Is the Difference Between the Blue Ox SwayPro Weight Distribution Systems BXW1003 and BXW1000
    The Blue Ox SwayPro Weight Distribution System part # BXW1003 is for trailer's with an under-slung coupler like part # CA-5335-B. If you have an over-slung coupler like part # CA-5400-B then you will need the Blue Ox SwayPro Weight Distribution System part # BXW1000 or you can just swap out the head, the Head for Blue Ox SwayPro Weight Distribution Systems part # BXW4011.

  • Does Flipping a Single Axle Cause a Drastic Change in Tongue Height
    The tongue height of your trailer is going to increase in relation to the amount of lift gained from the Dexter Trailer Springs Over-Under Conversion Kit part # K71-385-00 for 3" axles or part # K71-384-00 for 2-3/8" axles. The amount of height you gain will be equal to the diameter of the axle plus the height of the leaf spring seat and stack. Basically, the over under kit raises the trailer's frame and since the coupler is attached to the frame, it is going to raise that as well. In...

  • Is There a Weight Distribution System that Will Fit an 8 inch Tall Trailer Frame
    I have a solution for you but the Reese Weight Distribution w/out Shank # RP66021 that you referenced won't work well for you due to how tall your frame is. So what you'll need to do is install an under slung coupler on your trailer like the # CA-5335-B which basically gives you a coupler that attaches to the bottom of the trailer frame so that you can use a weight distribution system designed for underslung coupler like the # BXW1003 which has a tongue weight range of 750-1,000 lbs.

  • What Is The Difference Between Weight Distribution And Underslung Weight Distribution Systems?
    Great Question. Underslung couplers on trailers look like the trailer frame is sitting on top of the coupler. For an example of what one looks like check out the etrailer.com A-Frame Coupler Underslung # CA-5335-B. I attached a picture of one for you to check out as well. I reached out to Blue Ox to get the specific differences and there is only one difference. In the design of the Blue Ox SwayPro Weight Distribution w/ Sway Control - Bolt On - Underslung, # BXW2004, they accounted...

  • What is Difference Between Overslung and Underslung Trailer Coupler
    An underslung trailer coupler is one that attaches to the bottom of the trailer frame and an overslung one is one that attaches to the top of the frame. The Replacement Head for Blue Ox SwayPro Weight Distribution Systems part # BXW4011 is for trailers with an overslung mounted trailer coupler like part # CA-5400-B whereas the Replacement Head for Blue Ox SwayPro Weight Distribution Systems part # BXW4012 is for trailers with an underslung mounted trailer coupler like part # CA-5335-B.

  • What is the Difference Between Blue Ox SwayPro Heads BXW4011 and BXW4012
    The difference between Blue Ox SwayPro heads # BXW4011 and # BXW4012 is the angle at which the trunnions are relative to the head. Head # BXW4012 is designed for underslung, also called bottom-mount, couplers so the bars are not at as a steep of an angle compared to the standard version # BXW4011. It is hard to tell without looking at them next to each other. An underslung coupler would look like # CA-5335-B and would be mounted at the bottom of the tongue rather than at the top like...

  • Adding Different Bolt-On A-Frame Trailer Coupler to Rusted Trailer in the Woods
    Well, that is a coupler, though it is in bad shape. It is a bottom mount or underslung coupler like # CA-5335-B. You can check the ball cavity to see if it is in working order but all that corrosion makes me think that using its coupler is not going to work. In order to use a regular coupler you will likely have to cut off that bottom mount coupler so a new coupler will be able to be lowered on the ball. The jack will also have to come out to be able to install a new coupler. As long...

  • 2015 Jayco Jay Flight 27RLS Coupler Lock Recommendation
    I pulled up a picture of your 2015 Jayco Jay Flight 27rls and the coupler looks to be an underslung coupler like the part # CA-5335-B. Which then for a lock that is specifically designed to fit this type of coupler we have the part # AT89006 from Atwood that will work great. I attached a picture of this lock installed on a coupler for you to check out as well.
