nope. the fabtech 6 inch kit has the same upper arms as the 7. the difference is a 4 inch lift spindle versus the 3 inch one.
my advice: im guessing this 6 incher is a used kit, based on your wording. if so, dont get a used fabtech lift. they arent that great, unless you are getting a killer deal....the CST 7 inch is obviously a huge step up in quality, and its not THAT much more than a fabtech
