    Dude he just wants to swap gears not carriers. ASR and TCS have nothing to do with gears. I put 4.10s in my M6 without changing squat and retained both. Just get the gears and a full install kit you may as well do it right while you are in there.

    Just so nobody is confused, we don't know what you mean by a ''4-channel posi.''

    All F-bodies have the OPTION for ASR, beginning in 1996 or so, or maybe it was 1998 with the advent of the LS1. I am glad both of my LS1 cars did not have this intrusion on my driving pleasure.

    Anyway, non ASR (or TC, if you want to call it that) cars have a 3-channel ABS system, where the ABS brain checks the RF, LF, and the back two tires as one assembly. ABS is more important for the steering wheels, hence the individual front speed sensors. On this system, it has a sensor on the top of the diff to measure cumulative rear wheel speed.

    On ASR cars, the brain needs to know actual wheel speeds to figure out if rear wheel(s) are spinning faster than the fronts, to invoke the (dreaded, IMO) ASR. So therefore they have a 4-channel ABS system, with wheel speed sensors at the outer ends of the rear axle.

    So, if somebody has ASR, and they want to keep it, and they are changing the whole differential (to a 9'', perhaps?) then they need to be sure the new diff has the wheel speed sensors for the 4-channel ABS/ASR cars.

    Otherwise, they can get a new diff with the standard single wheel speed sensor mounted on the center part of the diff itself, since this is the only wheel speed sensor needed for the 3-channel ABS system which was stock on these cars. The ASR was an option on all cars, but towards the end of production more and more cars had it, but could be deleted on special order.

    cliff notes:
    These cars come with 2 or 3 series posi carriers
    and 3 or 4 channel ABS/TCS
