    Default Max Coupler Wearing Out

    I have what I think is a second generation "Mod 1" Max Coupler, purchased in May 2013. There seems to have been lots of changes in design and ownership over the years and pictures are hard to find but roughly:

    First Gen


    Second Gen On mine the yoke's bolt bushing has a shoulder (Mod 1?), but no grease fitting for keeping the bushing lubed. Frequent disassembly, cleaning, lubing and reassembly
    is required if you frequent dusty trails.


    Third Gen With the yoke's vertical steel wrapping around


    Maybe later a zerk fitting was added to this gen

    Fourth Gen The Yoke has the alignment "wings" to aid in coupling and a grease fitting

    On mine the Yoke's steel bushing (they call it a Crush Sleeve) no longer has a round exterior and the hole in the yoke is out of round too. This results in a lot of vertical slop in the yoke.
    I've made sure that the large bolt is tight and does not move.

    The bushing exterior varies from 1.20" to 1.22"

    The Yoke's hole is more of an oval with the side to side being 1.22" and the front to back being 1.24"

    When the bushing rotates into the "worst" position the gap can be .040" front to back.

    Instead of the yoke staying horizontal the play can cause it to noticeably wobble up and down. I measured .050" in the vertical plane and it makes clunking noises. How long it will last until failing? Dunno.

    My attempts to engage CU Offroad have gone nowhere. I did attempt to order a new yoke from them last week but that failed too. Phone calls go to black hole voice mail. It turns out that the website is deliberately designed to keep the end user at bay as stated to me by "JR" when I finally got a rather hostile return call and a very unhelpful follow-up email reply. I never asked for anything free and I've paid full price for the yoke. Mine is 4 years old so it is what it is. It would have been nice to have the owners tell me what the current yoke design is like. Pictures are few and far between.

    So for anyone who actually offroads a lot with a Max Coupler be sure to keep an eye on the wear in the yoke.

    I reluctantly ended up ordering a new yoke from Knight Offroad but I have no idea when I will receive it.

    This came on my tent trailer, tried to get more info about it like where do I order replacement parts, what's the warranty, etc by calling cu offroad but there is no contact number. Just their ****ty website contact form, tried that a half dozen times - nothing. So after doing some digging this is what I came up with

    Chris Ulloa
    Company name "Cuamco"
    717 N Coney Ave
    Azusa, Ca 91702
    702 674 6292
    818 565 5522

    info@kilbyenterprises.com
    chris@kilbyenterprises.com (obviously not kilby as brad kilby sold the business back in '10 or '11 IIRC)

    https://www.facebook.com/profile.php?id=100013315657696

    I tried calling the numbers I found and got nothing. I tried emailing the email addresses and got nothing. So at this point with less than 3k miles of use on CU OFFROAD's "amazing" coupler with their "Tough-Flex formula" polyurethane bushing that supposedly they have never had to replace under warranty (because they don't answer ****ing calls/emails??) and with the rubber pads on my unit FAILING and the fact the company seems to be a joke I will be throwing this pos in the trash this winter when I find a replacement option.

    I got one too-late reply in an email and it was a "could'a-should'a-would'a" telling me what they might have done and what might have happened but avoided any discussion of the problems due to the wear around the yoke's bushing. Both the angry phone call and the email seemed to imply that everything was my fault.

    It was also stated that the "owner" of CU Offroad is here on Expo and supposedly was corresponding with me:

    "...the owner saw your recent thread on a "winged" yoke assembly, and having corresponded with you before apparently, was more than willing to hook you up with a deal for your loyalty."

    That was pretty weak.

    I replied to that one email but my reply was not acknowledged.

    The funny thing is that the one single email to me started off with this statement that somehow justifies the non-communication with customers experiencing product failures:

    "Our focus is making sure we manufacture a quality product and second to that is manufacturer/product support.

    So if they are shipping out inherent design problems how will they ever find out if they don't bother to talk to customers who operate the product in the real world??? I believe that the approach of the hard steel bushing riding in a softer steel yoke is destined to be a wear problem even with a grease fitting in place.

    Pintle/Lunette combos are pretty solid and don't suffer from development issues that new approaches can struggle with.

    I've not kept mileage logs but my trailer is definitely operated in the (dusty) off-road environment as seen here at Expo and on my blog. I would have thought CU OffRoad might have shown even a slight interest in the wear issue but they didn't appear to care.

    Are those two pieces pulling apart or is it what they are now shipping??? That is strange looking.

    I have an older yoke but the trailer piece with red bushings is like this one with a very small gap between the two pieces:

    Just got off the phone with AT trailers in AZ - I asked if I could purchase the new style yoke for my current max-coupler. "No you have to buy a complete new one".....Thank sweet baby Jesus I canceled my original TD order with that company in 2013 after visiting SoCal TD's

    You can buy the new yoke at a few places. Right now it is $135 and free shipping at Knight OffRoad. The web site is a little goofy but what you'll see is that a complete set is $235, the Yoke is $135 and the swivel tongue piece is $100. They communicate a bit better than CU Offroad but improvements would be welcomed.

    Knight Offroad has some decent pix of the new yoke (unlike the manufacturer)
