How do I find out what kind of differentials I have

Can someone assist me in finding out what type of diffs and gears I have in my truck? I have a 1994 chevy silverado ext cab. 4X4 with the 5.7L engine and 4L60E transmission.

if they havent been changed before.... call ur dealer and give them ur vin number and they'll give it to you.

Thanks. I need to call them about the windshield wiper recall any how.

If it's a half ton it should have an 8.5" IFS front. Rear is either a 8.5" 10 bolt or possibly a 9.5" 14 bolt SF. Count the number of bolts on the rear diff cover to find out. 10 is a 10 bolt and 14 is a 14 bolt :smokin:

The 14 SF is a decent rear, and IIRC as put under the truck that got the factory towing package.
