      Excellent fit and finish; enabled to use a non-factory shift knob.

      Review from Jam Nut Collar Adapter - Silver (15-18 GT, EcoBoost, V6)

      Don't throw your money away

      Bought a new shifter knob and yes, when I tried to screw it all the way down it did lock up on the reverse pull up. But thinking out side the box, I simply took small, 1" square pieces of a rag and one by one stuffed them inside the knob carefully compacting each one. After about took 3-4 of them I then proceeded to crew down on my new shifter knob. After a few tries and alterations I got it just perfect and was able to tighten the knob down hard enough so it didn't move (without a lot of force) and was still able to put the beast into reverse. I then took this collar, wrapped it up the remaining rag and threw them both into the garbage.

      Reverse lockout

      Can't get any easier than this. Just screw on the shifter, adjust for lockout to engage and install the shifter ball of your choice.

      Necessary for aftermarket gearshift knob

      The black looks much better, but wish there was a "set screw" to keep it and the aftermarket knob in place.

      Don't work

      I think you should let your customers know that it only works with the stock shifter knob . I have a hurst knob and the collar too big won't work

      Jam but collar

      Works great. Would be better if it matched the polished look/finish of the reverse lock out. Other than that great product.

      Does the job!

      I went slightly un-conventional and used a BandM hammer shift knob. This Jam nut collar lets you keep the reverse lock out and use whatever knob you want. ALSO raises the knob, which I really like.

      To tall

      While it works as designed it raises the shifter to street truck proportions and also drastically increases the throw and vibrations felt while driving, so unless that's what you are looking for I would steer clear

      Jam Nut Collar adapter

      Only gave it one star as I still can't figure out how to install it. Neither this unit or the shift knob came with any instructions. In the "olden days" you simply unscrewed the old knob and screwed on the new. Apparently this is not the case with this one. If I could be provided with some instructions it would be helpful!!!

      The adapter is solid piece, you can feel the quality. Very easy to install and to adjust the shift knob, took less than 5 min. Overall very satisfied with this product.
