You will be fine man, the differences are the RE7s can handle more weight than the RE6s at the same pressure so you will just have to run more pressure in the RE6. When I switched from the RE6 to RE7 I ran 20 less psi to get the same amount of lift. RE7s have a larger stroke as well. They have a chart comparing all their air springs if you want more information.
