Body or Suspension Lift

That's the bump stop on top of the leafs

 

If it's on top of the springs it's effectively a giant bump stop which will keep the springs from coming any closer to the frame (less upward travel).

 

Ok. But that's all I have, so it's just a leveler in the front??

 

Ultimately, your truck has 184k miles on it and has some sizable front spacers. Put those two together and it makes sense that the front CV boots are bad. Lift + Time = Maintenance

That 4 leaf spring in the back could be a factory pack or could be aftermarket (which could provide lift in the rear). Hard to tell without markings and better images.

 

Thank you sir.

 

No problems! Get them boots/CVs fixed and enjoy your ride. If you ever decide to remove the spacers and do a suspension system check out the suspension forum section. TONS of useful info.

Or just hit up @HeadStrong Off-Road for a good deal on suspension lift kits. These guys are awesome and always seem to have the best prices too!

 

@Kyitty is spot-on. Within the Suspension forum, I recommend you start by perusing the Tacoma Lift FAQ/Guide and Suspension Lift Info threads.
