Hello,

I recently upgraded to a 3/4 ton truck and it has the 2.5" receiver. I didn't want to mess around with the adapter so I picked up a Reese Titan shank however it doesn't fit correctly.

Please explain why it doesn’t fit correctly.

Doesn’t fit into the receiver?

Not long enough as you state below?
.

So my question is what are you using for a weight distributing hitch that has a 2.5" shank with about a 12" extension from the hitch pin to the holes for the WD head? I need the clearance so I can put the tailgate down when I'm hooked up.

Note that the longer the shank, the longer the lever arm on the receiver cross tube (a torque tube).

That would reduce the rating of the receiver and also increase the amount of WD bar travel required to do the same work a shorter shank would require

Thanks,
Mike

You also said you don’t want to mess with a 2” to 2.5” adaptor, so using the old one is out, right?

What is getting in the way with opening the tail gate ? Most TT’s have room to drop the tail gate and what is different with yours ?
