Best 3" lift option for stock '15 TRD Off-Road?

For the price? Light Racing/SPC

 

It all depends on your budget. There's wide range of prices out there from 250-850, I only have experience with LR racing UCA'S also known as SPC UCA's. Each has their own pros and cons. There is so much info on this site I recommend doing your due diligence and read what you can on each one. I'm just not knowledgeable enough to recommend any particular one.

 

Have you heard of Camburg's Balljoint UCA? the Total Chaos UCA I heard that you have to constantly re-grease them. Is there true with all of them? Budget is 650-850.

 

Haha, I've heard of all of them at this point but, I only know what I've gleaned from reading about others experiences with them. With your budget your looking at the higher end of the spectrum. You may want to look at Total Chaos which seem to be TW a favorite despite the greasing and Icon.
