Typically the stock lines/hoses will work even with a 2 body lift. If you have 2-3 of slack in the hoses you won't have a problem. IF you are using hard lines from the master to the valve you will need to take a closer look. Most aftermarket hard lines will have a few large coils which will allow you the stretch them out. Without seeing exactly what you have existing it's hard to know for sure if it will work.
