Greetings & Salutations......First off...Thank you to everyone who has ever posted on this or any other board. The access to information and folks willingness to share said information has proven to be invaluable. Many thanks!!! Now, I'll apologize right off as I'm sure this has been beat plum to death, but be damned if I can find the info anywheres. I'm a brand new Titan owner. Just bought a 2012 SV 4x4 C/C with a 6" RCX Lift and spankin new Nitto Terra Grappler G2's. Gosh I love this truck!!!! I've been reading and reading and reading about gearing and options for Titan owners but the only reference I've found is for the M226 rear and M205 Front ends. Does anyone know for sure if the install is the same to put a Tru-Trac in the C200 rear end? Also how can I find out the model number for the Front end in my truck and what kind of gear options exist for that? I've read near about every post I can find and haven't run across anything for those of us without Big Tow/Off Road options.

Many thanks!!! And again, I do apologize if this is a dead horse I've saddled.

You should have the M226 rear axle and M205 front diff. The C200 rear is used on Frontiers and Xterras, but to the best of my knowledge, was never used on the Titan (others here will surely correct me if that's not right).

There are only two rear axles listed in the Nissan parts system for the 2012 SV 4WD - standard, and a second for SV "sport" and "big tow" (same P/N). The standard axle has the 2.94 gearing, while the sport or big tow has 3.36 gears. Front gear ratio will match the rear. SV should not have an e-locker rear diff (no switch on the dash to lock the rear end, right?), so a TrueTrac installation is fairly straight forward, although correct setup is not trivial.

You can find other gearing options from the site sponsors who carry differentials/related products (use the Forum drop-down menu, and go to the Supporting Vendors list - JTS has the parts, for example). Front and rear must always match, so if you change one, you have to change the other, of course.

Hope this helps!

dreep is correct. C200 is Frontier lighter duty intsy weentsy axle assy.

but the sucky part is if you go beyond the gear ratio of whatever was installed in your rig, the cruise control won`t work.

ie: installing something simple as a 3:36 into a diff that originally had the 2:94`s...

that sucks bc I like CC. and stepping up to a better gear will kill it. or I should say be in need of an ECU of that flavor with the lower ratio. But I have yet to come across any info here stating that another ECU will get the CC working...

if I am wrong, please correct the info.

NP... some here won`t bust your balls, but there are some that will without a doubt...

ie: if I choose a D60 axle set up and ratio of my choice that is different than what My ECU, output shaft speed sensor and ABS see, the cruise no workie...
same applies if I go with a fabricated F9, lots of precise gear ratio`s, but ya lose the cruise...
there were a lot of past members who did nice mods asking for a fix years ago, I never came across any such fix in recent times...

Not my style, not PR's style, lots of other good folks here. We all have to learn. My pet peeve is those who don't listen, certainly not those who ask good questions, or ask for help.

These are great trucks. I'm sure you will get a ton of fun from yours. For improved fun-factor, if you truck isn't already UpRev tuned, check it out. Jeff and Joe from Cajun bPipes (site sponsors) have the stuff to help with the fun factor!

Welcome!
