I purchased the Curt 60609 "Ford Factory-style Gooseneck Ball and Safety Chain Anchors" kit from a local trailer supply shop, for my 2014 Ford F250 with factory-installed 5th wheel hitch prep package. The kit's gooseneck ball fits perfectly, but the safety chain anchors won't turn into place (yes, I removed the locking pin before trying).

The trailer shop had to grind down the upper surfaces of the bottom flanges for the anchors to fit. Is this a known problem the Curt kit? I called Curt about this, and they sent a new set of anchors, but they also don't fit. I'm worried about using the anchors that were ground down.

 

Ok how much did they grind off of them, couldn't be too much.

 

Looks like about an 8th of an inch was ground off.

 

I really don't think 1/8th is going to comprimise any strength but I would definately take a few pics and send them back to Curt mfg. They are going to want to see what's going on so they can fix it on their end and hopefully reimburse you for your trouble.

 

I test fit the Ford OEM chain loops branded by Ford and manufactured by Reese/Cequent several years ago, after reading reports from early adopters who described how their chains let loose in the bed, hooks, holders and all.

I found that by simply wiggling the factory chain loop, it would come free from the puck receiver in the bed. Mentally picturing a gooseneck horse trailer trundling over the unpaved roads on the ranch where I worked for 6 years, there was no way that I would trust the original chain holders to stay put, unless the hook were large enough to keep the little plate inside the loop from popping up. Even then, a change in position from 90 degree turns can shift those hooks inside the chain loops, altering the position of the chain hook over the pop up plate, giving it clearance to pop up.

The Curt design appears to be better, although I've not seen these Curt loops personally. I don't blame you for going this route, compared to the factory loops. As long as the ring to the lynch pin doesn't pop up over the ears on top of the Curt casting, the combo J pin / Lynch pin set up should keep the Curt holder from rotating 90 degrees regardless of the hook position inside the loop.

 

I heard about the problem with the Curt chain loops and ordered the Reese chain loops instead. No problems.
