Are they tundra 5100s? Assuming they are you shouldnt go above the third perch on them with tundra coils. I never even went that high with mine. How much lift are you getting out of the front end at that perch height? Anything past 3" of lift will push your truck pretty hard. Stuff wears faster, gets harder to align, cvs break easier. if your at 3" front lift your best bet is to drop the rear down with some different springs. If you like the height then add a body lift.
X2 on what he said ^. I will say when I got mine from him they were on the second perch. Which means they had 3 more spots to go up not two. If they only have two notches left then he has bumped them up once already
