2017 TRD PRO Lift

Anyone know how much you can lift a 2017 trd pro with fox suspension without voiding warranty.
Also, are spacers necessary for BF Goodrich
K03's?

 

K03's? Did a new tire come out or do you mean K02?
Lift on a pro is the same as every other 3rd gen. I've read a lot about the pros and seen a lot of measurements and the pro doesnt ever measure to be any taller than the other models. Most lifts give 2-3". Are you wanting to add lift to the stock pro suspension or upgrade to a better fox suspension? All lifts will void any part of the warranty that can be proven to have caused the issue by changing parts.

 

No lift will void the warranty other than the parts you replace and you can lift the truck as much as you want.

The need for spacers depends on the size of the tire and the wheel backspace and offset.
