      I can not use it in my JK. It does not fit on the automatic version.

      nice addition

      Nice looking and feels comfortable. Heavy, so it vibrates around a bit. This causes the ring to bounce or vibrate. I may end up taking the whole thing out to weld it in place; since I like the look with it on but the noise is annoying. You could remove the pin and ring, but the spoon may come off if you do. Comes with a conversion kit, but it was not needed for mine. I plan to Loctite the set screws at some point. * 2012 Jeep JK Rubicon

      It was cool when I first got it but the screws would come loose often and it started to rust after three weeks.

      It's the bomb!!!

      It adds some grit to the rig. It looks like it belongs and it is a great fit. It handles perfectly and I much prefer it over the stock one it came with. It rattles at little bit depending on gear and surface. Adds character to the grenade

      Cool Shift Knob

      This is a great addition to the inside of our 2004 Jeep Wrangler. I give it 4 stars instead of 5, because the pin rattles a lot, which is probably common. I didn't think about it when I purchased it; but when it is cold outside the grenade is pretty cold and hot (warm) when it is hot outside. Other than that, it is a great conversation piece. It also stays in place, solid.

      Solid Product

      The install was easy, it is solid. The only part I don't care for is the rattling of the pull ring, but it's not bad and a small price to pay for the coolness factor

      Unique and rugged

      This grenade shifting knob is a heavy, unique, comfortable and rugged piece that was easy to install. I used lock tight on the set screws and the fit was tight but works well on my 2014 Jeep Wrangler.

      Awesome nob

      Everything fit perfectly. The only exception would be the pin\spoon rattling.

      Bad A**

      Bring a lover of military type stuff, I just had to get this on principle. Installed it the day I got it, man this thing looks AWESOME. Now. I want another one or even the baseball grenade for my 4x4 shifter!!!

      Cool Looking Shifter

      I received this shifter yesterday and installed it in about 20 minutes. Search youtube and there are plenty videos on how to remove. Make sure the grenade is angled just right for your preference and tighten it in! like the other reviewers have noted this thing rattles like crazy, I just used some superglue to hold the Clip, Pull Ring and Lever still.

    Will you guys eventually make one for an automatic and not just for manual?

    • This would look pretty nice on an automatic, Perhaps RockNob would come out with one for the Automatic Jeeps. Right now we solely have these for the JK's with an automatic transmission: 1. Item J18034 2. Item J18171

    I want to put two styles of grenades in the jk. Wondering if this one will mount on the transfer case shifter? I don't see why it wouldn't but would rather check before purchasing it

    • The RockNob WWII Pineapple Grenade Shift Knob is designed specifically for the shifter. We have not tested this on the transfer case, but it is expected to have clearance issues due to its horizontal mounting.
