I have an 07 nnbs lt1 crew cab 2wd and I am looking to trade gear ratios. I would like to swap my 3.73 open rear drum axle for a 3.23 open rear drum axle. If you have a 2wd lifted truck with big tires and the 3.23 rear diff than this could be a good swap for you. My rear diff is in like new condition and we would be doing a swap of the complete axle not just the ring and pinion. An axle from an 07-09 should work. I am in the Phoenix area of AZ. Would anyone like to trade axles?
