The install is not terrible, but difficult enough that you should set aside a few hours. I would rate it a 2 out of 5 with 5 being most difficult. You will need to a jack & some jack stands since you have to remove the shifter from below after the exhaust & drive shaft are out of the way.
I've got the TiC short shift lever, front shifter bushings & knob. I love the difference they made regarding gear engagement. The bushings alone will make a noticeable difference. I recommend doing all 3 even if you decide to only use the TiC shifter & bushings while using another shifter.
