New 2018 with 2WD - going to upgrade to a pre-runner type offroad truck

The first thing I want to do is upgrade to a locking rear differential. This truck came with something called: "Automatic Limited-Slip differential". I'm assuming that's for traction control?

What is the best route to getting a locking rear differential without sacrificing my warranty? Normally, I wouldn't need to ask this question, but because it has the Limited-Slip rear differential thing, I'm thinking maybe I can upgrade it without a full kit. I'm not sure, and know you guys probably already have the info.

Once I have the locking differential, I'll upgrade the suspension and put a small lift/larger tires. And that'll the full extent of my mini-pre-runner for taking the wife and kids out to see the mountains.

Now.. since this type of thing will inevitably turn into a giant bash-fest about not needing 4 wheel drive. Let me say all the following to try and avoid getting nothing but those types of replies:

I live in the desert. I've had 4wd trucks and/or Jeeps my whole life and the thing about the desert is: You don't need 4wd. So this time, I bought a 2WD for the first time. I wanted to save that extra $2500 and put it into things I'll actually need/use (like a locking rear differential).

I know! You DO need 4wd if you're into rock climbing or sand dunes or any number of other specific sub-group of off roading (or if you live some place that actually sees rain and gets muddy)... But for typical desert trail running with mild hill climbs on pre-made trails/roads... You just don't need 4wd.

I've had 4wd trucks my whole life and have never put one into 4 unless I'm climbing a hill WHILE towing a trailer or while at the dunes or whatever. This truck is going to be for trail riding on decent trails/roads at 10mph with my wife and small kids to get them interested in the outdoors. Nothing more.

If you disagree with me that's fine, but please: let's argue about it another time. Right now I have specific questions about my new truck and would like some advice about my next steps.

Thanks!

 

2wd Crue!

 

I would think getting a real locking diff like the ARB would only modify the warranty if something goes wrong with the diff. Not sure

 

Once you modify the drivetrain, you’re risking drivetrain warranty coverage.

It will never be limited to the diff alone.

 

For what it would cost to add a locker, plus install, you may be better off getting a 2wd TRD Offroad that has a factory locker. Then it’s all covered under warranty. That’s how I got my first tacoma. After getting stuck with my family in a regular dirt road during bad weather, wife told me I made a mistake. But if you plan accordingly the 2wd and locker combo will suit your needs. I had a lot of fun bush wacking my way out of some sketchy spots. Oh and the sick burn outs with the locker engaged!

 

Have you even tried the traction control in your intended driving environment? You probably don't even "need" a locker...

 

I haven't needed one yet. All the times I have been stuck..... a locker wasnt going to get me out.

 

That's my point. OP talks about how he never needs 4wd, but thinks he "needs" a locker instead?

an open diff 4x4 will always have more traction than a locked 2wd... I always thought it was funny that Toyota put lockers in the pre-runners.

 

No point in debating.

The best lockers for Tacoma is the ARB air locker, it's instant and has the perk of on-board air, so you can air down for desert runs. A good gear shop can install this no problem. It will void your rear axle warranty 100% but its expected.

I would want a quality suspension if you plan to go fast, a external bypass shock would be ideal like a fox 2.0 or even the TRD Pro shocks.

As for tires, if you focus on sand, these look awesome, I'm not a sand guy but the tread looks appropriate for it. General Grabber X3 red lettering!!
