I'm looking to swap my 05 Nisomo 3:36 gears to 3.69. First of all, anyone know if they are campatitble with lockers? (i would assume it would be since they would be from a manual Frontier) Second, is there any other place to get them besides a Nissan dealer? I have 33's and i'm looking to some of the power back and more since I'm still towing. I have been looking to get 4:10 but I don't know if I really need that much power. Thanks
Where could I find some 3.69 gears?

KC Manual Nismo has 3.69's so that answers the compatibility question.
rarely find just the gears. Typically you buy the whole axle assembly used and install that. Keep in mind with 4WD you will need both.
The 3.69 is the rarest axle around, and one of the most desirable (for the same reason you want one).
Whole axles are more expensive, but are easier to find. About the only time you will ever see a used set of 3.69 gears is if someone had a set and went with even more gear. But the extra expense does have benifits. You are not setting up gears, or more typically paying someone with the proper tools to setup your gears. It is now an easy axle swap.

I have both ring and pinions , front and rear.
I also have a whole 4 banger assembly with 3;69 gears .
Made a mistake and bought ,then realized it was for a banger.
Will sell but the carrier, ring and pinion is still in the diff.
Installed a a separate diff I bought.

I'll side track this a little. Have you thought of installing an XTP intake spacer? it's quite a bit less money and helps move the power to the low and midrange rpms a bit. NOT a replacement for a gear change, but, a good stop gap. It helped get rid of that engine lugging I was having in the 35-45mph range around town.

The 3.69 uses a different carrier than the other gears, so you can not just buy a set of ring and pinions and install in your truck . The rear 3.69 is the harder axle to find. S see it on carparts.com though. Seems like a front 3.69 diff is fairly easy to come by. I bought a used one for about 300$.
