I'm thinking about switching out the shifter knob for a grenade shifter. I think it looks cool, but primarily I think the weight of the grenade may buffer the vibration/rattle in the gear shifter it seems most manual jks are prone to have. Would there be any negative effects on the transmission if I switched out the knob? Anyone know of any other weighted gear shift knobs for the jk?

 

Not to rain on your parade, but I had a grenade shifter, had some decent weight to it. Kept popping out of gear, so I ended up going back to the oem knob. There may be a lighter solution out there - best of luck!

 

Good point! I didn't think it cause the shifter to pop out if gear. Hmmmm.

 

I ran one for 2+ years on my '07 with no issues and will be switching it over to my '15 as soon as I get around to it.

 

Do you have a link or more info? I really haven't looked much after my first experience. Is it fairly light?

 

I'm interested as well.

Nothing fancy, the lemon grenade fits great in the palm of your hand and there are 3 set screws to keep things tight.

 

I made one for my old YJ, it was very uncomfortable. Went back to stock.

 

Just some weights I pulled off of Wikipedia:

M67 (baseball) -.875 lb
M26 (lemon) -1lb
MK2 (pineapple) 1lb 5oz

I like the baseball but wish it mounted on its side. I may go with the lemon.

 

I've had this pineapple on mine for 3+ years. it's a dummy I drilled out and tapped a set screw into, it's rather heavy and haven't experienced any issues yet, I did remove the spoon and primer apparatus because it was rather uncomfortable
