Ultimate setup - so freakin' expensive (Like $9000 installed), but look at that final ratio. I love the idea of a stock looking rig on 33's-34's that has some stupid low crawl ratio choices available.

You win so far.

I don't have a damn clue what my ratio is but I just got a 98 5 speed so I assume it's fairly lowish (I know it's definitely lower than the 4 speed auto) and it can definitely go slow in 1st 4lo. Not currently planning on turning it into a total crawler since it will be my only personal vehicle for all sorts of mountain fun once I sell my Nissan Rogue (I still have a company car for work). Seems to be plenty enough for me atm just doing moderate offroading.

Okay you got me to actually look this stuff up and learn more about my truck

Please tell me if I got any of this wrong.

Looks correct to me!

How does that work for you on/off road?

I've only offroaded twice so far but it works really well offroad. Just Saturday I went wheeling with a group and we did a trail with many sections that had 2"-3" of consolidated snow and it was awesome downhill keeping it in first except for one section with very deep ruts (it actually resembled moguls) where I picked up a bit to much speed and ended up bouncing at the bottom and stalling out (I'm a noob so I hit the brakes and then the gas when I should have rode it out). No damage thankfully.

Onroad (in 2hi obviously) I don't like how first and second interact but only a minor annoyance. Just a little jumpy going into second if I'm not gentle with the clutch. I'm also trying to improve the clutch anyway (worn spring bushings and possibly spring and I might need to bleed the system) so it might get better.
