    Get the build sheet from gm using your vin.

    During business hours select: question about a vehicle I already own. Give them your VIN and ask for the RPO build sheet.

    Hate to resurrect a 6 mnth old thread but,my tahoe is in the shop for a rear end rebuild.It's a 2005 Ppv (ex trooper) tahoe,it has the gt4 g80 (3.73).What would be a good all around gear?I'm on the road alot and the 3.73 does Rev the engine a little more ,I rarely tow.How about the 3.42?Maybe 3.23??

    3.08 with the 4-speed will be pretty slow and doggy. If the 3.73 is a little high for your liking, try either of those two, the 3.23 being better for cruising on the highway of course.

    Update, found this, posi track and 3.73s, but I have 33s, it is a diesel, so, 4.56 will be bad?
