    I have a friend who flat tows his fullszie bronco everywhere and he used a 2 5/16" hitch to make it. He claims that the 2" ball is not strong enough to flat tow the weight of the bronco. This concerns me because I have a 20' 10k bumper pull trailer that I bought brand new and it has a 2" hitch on it. If a 2" ball is indeed not strong enough for flat towing a bronco, then it certainly is not adequit for towing a 1500 lb. trailer with a 6000 lb. trail truck on it. I towed the trailer 250 miles to school with me and didnt have any problems. Logically the 2 5/16" ball is better but since the hitch is welded to the tongue of my trailer I want to know for sure if the 2" ball is strong enough for the load. Thanks

    Check the marking on the ball you are using. Each ball has it's own weight rating depending upon how it was made. In general most 1 7/8 are 2000#'s 2" range from 5-7k's and 2 5/16 range fron 6-14K's. I have seen 5K 1 7/8" and 10K 2" balls so I would assume the coupler you have would be good if using the properly rated ball. Also, look at the coupler, most have a weight rating engraved also. My 2 5/16 says 20K #'s, although the trailer is rated at 7K #'s And I use a 14K ball. So I know I'm good! :D

    My trailer has a 2" ball and I have used it to tow an 80 K20 many times before.

    I checked the ball that I have been using and its rated to 5000 lbs. but my truck/trailer combo is about 8000. I checked TSC's catalog and they have a heat treated 2" ball with a load rating of 10000 lbs. so I guess I'll be getting one of those. I forgot to check the hitch and if its no sufficient I'll be buying one of those solid forged ones.

    Eh, check your coupler to see what it's rated for. You won't find a stamped steel 2" one rated for more than 10,000lbs.

    You can buy 2" trailer hitch balls up to 12,000lbs. The difference is the shank diameter. I have a 10,000lb one I bought for like $15 from JC Whitney (it's name brand, but I forget what).

    Most drop ballmounts are only rated for 5,000lbs. Ballmounts rated for more usually cost a pretty penny.

    It'd take a lot to break a 7,000lb rated 2" ball that is properly torque. The coupler is probably more likely to break. The next weakest link is probably the weld on a large drop ballmount (~5" or so, usually rated for 5,000lbs or less).

    Yah the coupler I have is also rated for 5k. Its ok because I have found 2 companies that both make solid forged ones rated to 10k so I'm good to go.
