Troubleshooting Cannot Torque 5/8" bolts to 200 ft-lbs on EcoHitch Hidden Front Mount Trailer Hitch
Updated 01/12/2026 | Published 01/10/2026
Question:
I cannot get the 5/8 nuts to torque to 200 ft lb like the instructions say so. The lock washers start to separate and smush out between the nut and washer. What am I doing wrong?

Expert Reply:
Hi Kris; the split lock washers on the # EH37FR will slightly flatten/deform and the gap will close. This is fine, just make sure you hit that torque rating for the 5/8" bolts and make sure the lock washers and flat washers are in the correct position. Also, make sure you're not doing this to the 1/2" bolts since they require significantly less torque.

Hi Kris, my rv mechanic installed it so I can’t answer your question. Works great for my e-bikes though! Scott

This worked great on my RAM 2500. Easy install. I use it to install a bicycle hitch rack on the front when camping while pulling a trailer.

I had similar issues with the torque. I decided to install it all and take it to my mechanic to check it out with his tools. Working fine.

Hey, Thanks for the quick response. The split washers squish almost all the way out…they are widening and if I keep torquing it down they will just pop out. Can I replace with nylock nuts? Grade 8? The 2 bolts that hold the tow hooks torqued down just fine. Was able to hit 200 ft lb.
