Anybody else have to do this?

so did you raise your steering linkage too? if not you might run into some pretty wild bump steer and when you lay out your truck your tires might do some funny tricks...

Hahaha, now here is someone that works smarter not harder. Whats a little bigger wheel tub and who needs room in the engine compartment. Z'ing the frame just gives much more hassles as speedster said steering linkage too. Just keep doing what you are doing it will be just fine.

I did something close to the same, I z'ed my front in two places after I sfbd my stock frame and moved the steering linkage more then the arms( put it just like yours but got there from a different way) and it was not driveable at all any time I hit a bump or played with the air it was all over the road, you may want to look in to moving your linkage to if you havent already
