I just put on 285/70r17's yesterday and have a bit off rubbing. Not bad but noticable. How many turns should I do? And will the stock Rancho's be over extended in travel??

 

I put 285/60 17 on my truck and the way I turned them up was put my truck on level ground. Which was a shop floor at the time. And measured to my bumper on each side. And then turned them both the same to increase the height by 1in. And then measured again to make sure thats how much the truck moved up. I think it was 1 3/4 of a turn. And the truck leveled out too.

 

2 turns to level usually does the trick.

 

got ya on the two turns but what about the stock rancho shocks , will the extra travel cause the shocks to fail
