I’ll just try to keep this as simple as possible. For any of the coil spring lifts available, it is impossible to damage your CV axles by running those coils. AC coils of any kind, as well as OME coils of any kind, will not harm your axles, though they may accelerate wear on the cv boots (hence manual hubs). The trouble with CV axles can only occur when spacers are added. Usually a 1” spacer is safe. So, what we’re really talking about is the lift heights that are available. Check the weight ratings in the MD springs, as they’re rated to give .5” of lift under a specific load (likely similar to the weight of a front bumper). The HD coils generally give 1.25” of lift with no weight, but sag down below that when a bumper is added (.5-1”). AC coils will give a minimum of 2”, and will sag minimally under the weight of a bumper. It comes down to what you want your pathfinder to do in terms of weight capacity, lift height, and handling. Generally OME is conceded as the better feeling spring in terms of ride quality, but plenty of people like their AC coils as well. As for the rear, go with LR springs, there’s really nothing better.
