Changes needed with suspension lift?

So, I've been reading the posts in the various forums and have been learning about what is needed when doing an aftermarket suspension lift. However I want to make sure that I'm not missing anything. I believe the follow are needed, please correct me if I'm wrong:

Suspension 2" lift: Front & Rear
UCA: needed for max travel of front suspension
LCA: needed for long travel
Diff Drop: optional?
Carrier Bearing Drop: needed
New bump stops: needed
Extended Brake lines: needed
Wheel spacers: needed with new UCA?
CMC: needed if running larger tires 33"+?

Am I missing anything?

 

Suspension 2" lift: Front & Rear
UCA: needed for max travel of front suspension

• YES, but you can get away with no UCA if you stay below 2"

LCA: needed for long travel

• or mid travel or strength

Diff Drop: optional?

• 

Carrier Bearing Drop: needed

• 

New bump stops: needed

• can go either way, nicer bump stops are preferred

Extended Brake lines: needed

• 2" or below, no, anything above yes

Wheel spacers: needed with new UCA?

• or wheels with proper back spacing

CMC: needed if running larger tires 33"+?

• depends on rims and tire width, CMC need with some 33s

EDIT: STRONGLY CONSIDER ECGS BUSHING!!!

 

What is the ECGS bushing?

ECGS bushing replaces a poorly designed "Needle Bearing" that attaches the front driver side wheel/axle to the front differential. Lifted 4x4 Tacomas have a very high chance of a failure in the needle bearing which causes a grinding/pulsating sound when driving in 2WD. Big enough known issue that Toyota has a TSB for it. Search the forum for needle bearing to learn more.

ECGS = East Coast Gear Supply. Stand up folks. Have dealt with their owner directly as a customer.

 

So, it sounds like if you decide to upgrade your suspension and are wanting at least a 2" lift, there are more parts needed than just the front and rear suspension. I also forgot about the AAL options.

 

front coilover, uca and lca (both optional), sway bar relocate, ECGS bushing, rear shock, leaf pack or AAL, 1/4" spacer to correct taco lean, carrier bearing drop
