I'm wondering how far I can crank my torsion keys. 99 f150 scab lariat. I already have done some to make it level but I'm looking at putting some 2" blocks in the rear.I know putting too much stress on everything up front is bad but honestly the truck is on the highway95 percent of the time and will be getting it aligned after cranking them. A slight rake is ok I just don't wont it to look like an NHRA funny car. Or should I just put some1" blocks and crank a tad more

 

You can crank as far as the factory key's will allow you and you'll still be okay. However one side won't be able to go as high as the other, so you'll have to crank them to max, measure, and then lower one side down.
