I'm sure it's been mentioned here before but the stock gearing in the second generation is garbage. I don't understand how it could take such a step back from my first gen xterra. I will definitely be doing my gears asap.

I have the gears sitting here(only 4:11, only ones available with the 180).Will install soon.
I knew it needed gears the day I picked it up. On the test drive, I tried to take off in second gear, like my 3 previous trucks.It died.First truck without a choice of gearing.
My Dodge has 4:33 I ordered as an option.
Even with the new gears, I will continue to run 265/75/16.

Mine does second gear starts no problem. I can only imagine how terrible the non pro4x models are as far as gearing goes. Never owned a truck that you can't even drive over a rock without stalling. even with the rear locker it's far less capable then my stock xterra. I don't need it to be a rock crawler. Just able to get me up some rocks here and there without having to smash it. Kinda sad. But it does have more potential.

Probably because of the torque converter in automatics. My truck is a manual.

4.10 with 33's are in the near future and will work up from there.
4.56 gears and stock 31.7" tires + manual trans are AWESOME! If you are a manual and are going to spend the $$ to regear, get the 4.56. Then you have way more tire size options.

That's what my dad was telling me to rub if I was going to do gears. You run this set up? How is highway driving? Gas mileage?

Yes, I would prefer 4:56 but I am running a r180 differential. Lowest I can go is 4:11.

Highway mileage DOES suffer a little, however the performance and driveability improvement are worth it.
Stock gears = 18-19 mpg at 70mph
4.56 = 16-17 mpg at 70mpg

If I keep it at 65, maybe 18. 60mph about 19mph. In town is less noticeable, I can get 14 mpg fairly easy - 12.5 of I let her wind up to 3000rpm before shifts. (FUN!)
The real difference on the highway is that at any speed from 60+ mph, there is virtually no need to downshift to pass.

Here is a link to a neat gear ratio calculator I used this to figure out if I wanted to go all the way to 4.56. For instance, Stock 70mph = 2110 rpm 4.56 70 mph = 2606 rpm

Agreed. I have 4.10's with 35's. Mine's a stick shift. It's not bad, have to downshift on hills sometimes when I would prefer not to. 4.56's would be better. My rig is heavy as hell though.

Do they still not make 4.10 gears for the r180 in 6 speed? Everything I see says no but they are all old posts.

It's been awhile since I had to look into this, but what did the 3.54's come in? Tow package automatics came with the 3.36 gears and everything else I think got the 3.13's. I believe 2005-2007ish stick shifts came with the 3.54 before Nissan went to the 3.69 gearing in 2008.

If you wanted to swap 4.10's into a stick and keep the R180 you could find a carrier from 2005 or 2006, just the carrier, not the whole case. The carrier will fit into all R180 cases (I'm 90% sure of that.)

Search Results

^^ Hopefully that link works. Those should be all 3.54 carriers. Looks like Terryville Auto Parts (that's about 40 mins from me) has a couple for $150.

Or, you could go for broke (or go broke) and buy the R180 ARB (which is a 3.54 and down carrier) and the gear package and do it all in one shot. That's the route I'd probably go.

Thanks that's a lot of good info and I will look into it all when I get off work today.
