• What is the Measurement in Height on Underslung Coupler # CA-5335-B?
  Hello Jeff, Thank you so much for the diagram. I was able to get the measurement you requested, I am sorry I do not have dimensional drawing I can send. We didn't have any stock here at our Wentzville, MO location so I reached out to a friend at our Salt Lake City location and he said it is 3" tall at the spot you requested on the A-Frame Trailer Coupler # CA-5335-B. What kind of trailer are you putting this on?

• Ball Mount with Angle that Would Best Match Underslung Style Coupler
  Hey Miley, there aren't any underslung specific coupler balls available. The head of the underslung Blue Ox weight distribution systems does angle the ball back so best option might be a Gen-Y Glyder ball mount like the part # 325-GH-12005 that is cushioned but as it unloads it would tilt back like you are wanting.

• How to Clean and Lubricate a Difficult to Open Trailer Coupler
  Hey John hopefully it just needs a good cleaning and lubrication. It would be noticeable if something was bent or broken and even then it probably wouldn't work at all. I recommend dousing your coupler in WD-40 a couple times. Open the latch and spray as much as possible inside the mechanism. Just keep working it over and opening and closing the latch while you're doing it. Coupler's like item # CA-5335-B aren't the easiest to operate because they get all kids of gunk and road grime in...

• Difference Between Standard and Underslung B&W Continuum Weight Distribution System
  The difference between the standard and underslung B&W Continuum Weight Distribution System is the coupler style they are designed for. If you have a standard coupler like the # CA-5400-B mounted to the top of your frame then you need the standard Continuum # BW78FR. If you have an underslung coupler mounted to the bottom of your frame like # CA-5335-B then you need the underslung Continuum # BW88FR.

• Weight Distribution Hitch For 2006 Jayco Jay Flight 31BHDS With Underslung Coupler
  We can get you set up with a weight distribution hitch for your 2006 Jayco Jay Flight 31BHDS, though the SwayPro # BXW2000 isn't rated correctly for that trailer. That hitch is for tongue weights between 1,500 lbs and 2,000 lbs, andthe '06 Jay Flight 31BHDS has a 9,000 lb GVWR, so your tongue weight is going to be in the 1,100 lb - 1,200 lb range. From my research it looks as if the trailer also has an underslung coupler, so what you need is the following: - Blue Ox SwayPro Weight Distribution...

• 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.

  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.

• 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 a...

• 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...

• 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...

  Great Question. Underslung couplers on trailers look like the trailer frame is sitting on top of the coupler.

  With this being such an inexpensive part there is not a repair kit offered by the manufacturer for the thumb latch components of the A-Frame Trailer Coupler item # CA-5335-B. I wish I had an option for you but if your pin is no longer functional you will need to replace the entire coupler.

• 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 the...

• 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...
