Reese 20k for RAM oem hitch prep

Good evening everyone hope all is well. I have a question for those of you using a reese hitch with the RAM factory hitch preparation. I purchased another reese elite 20k for this RAM, as I really liked its operation on my 2015 gmc with universial rail system.

Upon mocking up, and test fitting my new reese elite 20k on my ram I have found that she just wont fit! As instructed I assembled the unit with everything loose, placed hitch in pucks, obviously slid into place with no issues. Tighten the head unit bolts which sucks the legs in and boom! the hitch is as tight as kryptonite. HOWEVER! I couldn't lift the hitch out with a crane if I wanted too so I loosen the bolts, make some adjustments, re-install, tighten bolts same thing!

I then measure my center to center distance on the factory hitch prep pucks, and the center to center distance on the TEE-pins on the hitch (with the head bolts snugged up)39-1/16" on the pucks, and 38-11/16 on the hitch so bang on3/8" too short on the reese hitch itself. This would be fine if it was the length of the truck as you are able to adjust the tee-pins front to back but not side to side. I have a plan to fix this... being a welder I can easily make up two full 3/16" spacer plates to cover the full face of the adjustment holes. However I am going to have to call reese to inquire about these spacer plates just for safety sake. I know there wouldn't be an issue with such a smaller spacer plate however I don't know what reese will say. I don't want liability to be passed onto me that's for sure. SOooo if I cant do the spacer plates I would say I am screwed as theres zero adjustment available in the puck system.

anyone else have this issue? with any hitch on the market ? I know I could use the hitch in this fashion as the t-handles do lock in place and there is zero play up and down but I feel as though there would be far to much tension on the Tee pins as they would be sucked into the sides of the pockets from tightening the legs, and there would also be zero chance of actually removing the hitch without undoing the hitch head bolts.

  • I don't have a Ram with a 3600 hitch, but have heard a few owners mention the leg bolts may need to be loosened a little for install. In any case the 3600 always fits, and the owners are happy with them.

    You can always call B&W and ask them. They do many installs, and have helpful people that answer the phone and your questions.

  • Most guys with factory prep seem to love their B&W and I don't recall hearing about any fit issues. They cost a lot but they're a quality product.

    You can also buy rail adapters that drop into the factory pucks. That would open you up to any rail mount hitch on the market, including non-traditional options like a rail mount Andersen. Here are a couple of options but there are others too.

  • WELL just made my phone call, not impressed. They wont go for the spacer plate idea which I kind of assumed. Aparently this fitment issue is a well known issue for the reese model for the RAM factory OEM prep.... which would've been great to know. So I guess my question is... before I go and send this hitch back in and buy the B&W.... does the B&W fit with zero issues?
  • I thought about the B&W, however when comparing it to my reese elite I wasn't "blown away" by the B&W. Not to mention its a 2400$ hitch here in Canada. I suppose if that's my only option I may have to go that route. Just about to give Reese a call
  • Send it back and get one of these. Drops right in and you will be impressed with the quality and ease of hitching.

  • yea I slid under the truck to have a look to see if I could adjust the pucks, but as hoefler stated, they are welded directly to the frame rails. I would have to think this is maybe a Reese issue, as I imagine the RAM frames "should" be pretty standard in measurement... I guess 3/8" difference is possible between different trucks? I re-checked the part number on the manual which is
    RP30160, and it checks out being for a 2015 RAM with OEM pucks.
  • My pucks are factory welded. I had the Ram 25K fifth wheel included with the purchase of my truck.
  • I could be wrong here but I THINK that the pucks themselves (on the truck) can be adjusted.
