Toytec ultimate lift

If I install the Toytec ultimate lift or the Toytec Boss lift will I have to replace UCA? Will these lifts work with stock UCA?

 

The lift will work with the stock UCA's. The question is, will you be putting larger tires on? UCA's are generally required to fit larger tires. Stock tires will certainly be fine, but larger tires may rub on the stock UCA's.

 

Using stock rims. 2014 TRD off road 4x4. Will be adding terra trails 265/75/16

 

Depends on if you like the way it handles with low caster. Make sure when you get aligment ask tech to get as much caster as he can cause most techs wont even pay attention to your caster.
