If you are wanting to rebuild your T56 yourself or have your own shop do it, we offer T56 rebuild packages from mild to wild to suit your F-Body! If your F-Body is making under 600ft/lbs of torque than we reccomend the level 2 rebuld package, however if you are making more than 600ft/lbs rear wheel then you may want to consider upgrading to the level 3 Extreme "Viper" rebuild kit which is good over 1,000ft/lbs of torque!!! And remeber if all of this is to confusing, just give us a call and we will be more than happy to go over it with you...
