The Trimax Dual Purpose Coupler Lock and U-Lock # TMX77FR uses unique keys for the locks. If you were to buy two of these I would expect the keys to be different.

If you're looking for a similar lock with a keyed alike option I recommend the Fastway # FA86-0015-316. This also fits 1-7/8", 2" and 2-5/16" ball couplers. You can actually choose the key number, in this case it is 316, so the keys will work with however many you need.

If you don't like 316 I have attached a link below which will take you to all of the Fastway locks with the different key numbers. I also attached some review videos for your reference.

We don't have a combo of the Curt Hitch Ball #C40008 and Curt Ball Mount #C45340. The ball mount is extremely heavy-duty, rated up to 17,000 pounds. I think it's safe to assume you don't have a torque wrench rated up to 450 foot pounds…

I spoke with my contact at CURT and he told me what gives the CURT Hitch Ball, #40038, more strength is the way it is threaded and that it is heat treated beyond what #A-90 is so that gives the 40038 the higher rating. He added that even though 40038…

Answer 5

If you have a bench vise you can put a cloth around the ball and use the vise to hold it so you can torque the nut to spec on ball #C40008. Like you said this ball doesn't have wrench flats so there isn't really a better way than using a…

Answer 8

I contacted MORryde and this does happen from time to time as the weight of the trailer can spread out the axles due to downward pressure on the springs/suspension. Odds are the 35" wheel base #MR27ZR will be the correct one for you, but they…

Hey Tom, I can definitely provide measurements and dimensions for the Equa-Flex Cushioned Equalizer #LC279687 and I have attached those dimensions below. Unfortunately, there is no database that we can reference that will tell us exactly what size…

Answer 10

Yes, axle spread and wheel base by definition are the same measurements. You will measure from the center of one axle to the center of the 2nd axle to determine what you axle spread is. This may be difficult as some wheels and covers will make this…

Answer 11

The absolute best cushioned equalizer that fits the dimensions you mentioned having would be the MORryde ALLTREK 4000 part #MR89DR as this is only option to provide vertical and horizontal cushioning. This would make a big difference and you'd be…

Answer 12

Finding the correct MORryde equalizer kit will be pretty specific, so I cannot tell you which will be correct without knowing the wheel spacing and axle capacity, unfortunately. With that being said, if you have the trailer's VIN, you may be able…
