What would you be most worried about of breaking first on a stock Tacoma?

Not me personally, but a few people I know even with chromoly axle shafts have broken them.

 

Spacer lifts are the ONLY reason that would happen to your stock Bilstein. I have seen it so many times.

Back on topic:

U-joints

 

So no one agrees that after upgrading shocks and spindles next step would be upgrading LCA's or UCA's?

 

The plastic armrest on the drivers door. I cracked it within weeks.

 

I mean, you can upgrade them, but the stock ones should not be breaking.
upgraded upper control arms could net you with a little more droop due to the unibal unstead of the ball joint.

or you could just say fuck it and go full blown long travel

 

Anymore of your concerns TW?

 

How about that plastic crap that snaps in on top of the factory rear bumper.

 

Hate that even on my first gen. Excuse to build a rear bumper

 

Crushing in the stock skid plate, and cracking the bed

 

Tie rod

 

I'd be more worried about breaking my wallet on all the mods listed on TW

 

on a stock tacoma, with stock tire size, you'd be hard pressed to break things. That's if you keep the wheeling within the capabilities of a stock truck. Push your limits, and cv's and axle shafts are likely to be the weak links, but that's almost on purpose. They're the cheapest to replace.

 

Tie rods, they are cheap so carry a few spares
