I have a two inch lift block on rear springs. Will it change anything on my yota if I put a three inch block in the front?

 

Very dangerous and very illegal. Blocks in the front act as leverage causing side to side movement which can end up with ubolts loosening and spitting the blocks out which can lead to causing loss of control of your vehicle. Welding them in is also out of the question, blocks in the front are just a big no-no.

 

Thank you rockrunner for getting back to me.
I will get a spring lift for my 85 then.
wanted to know before I did anything.

They have some 2.5" Orbit Eye springs it says on the front page.

If I'm not mistaken, Leonel runs the Orbits on his '89 SAS'd rig.
