I'm 6'7" with a 37" inseam and was having leg room issues in my TJ; received the Big Boy brackets for Christmas and installed them that afternoon. Amazing improvement made by moving the seat back only a couple of inches. Fully extended is actually too far back. Installation was simple, only took a few minutes. The only dislike I've noticed so far is that the chair sits noticeably higher although not actually that much higher; maybe 1/2" or less. I cannot wait to purchase the passenger side brackets so my 6'4" wife will start riding with me.
