hi there I am new to the forum. I have a 2015 denali. I have the rear 2" levelling kit from mcgaughy's. I am wondering if anyone who has done it before can shed some light on what I have to do with the sensor arms ? They told me they might not be building the correct length arms for a while. I have had some people tell me that it can't be done and others tell me it can but you have to cut the sensor arms. If anyone has any knowledge on this please let me know. Thanks
