Just depends on your truck. Some trucks will and some wont for some reason. My truck would lay frame before the crossmember. I Z'd mine because i wanted to go lower, it just depends on how low you want to go. If you Z the frame you will need to cut off about 4 inches of your frame and if you are running semi wheels you will have to shorten the control arms.If your crossmember hits before your frame and you are just looking to lay frame you can just section your crossmember. There is a pretty good thread on here on how to section your crossmember. This thread is old I have since got my truck back together and i didnt have to tub my firewall just had to move up my wiring harness.
