Question about 1999 Chevrolet K2500
How do I find out what the gear ratio is in my 1999 chevy k2500 crew cab 4x4 p/u truck?
Look on the glove box door. There should be a label with the a bunch of codes:
GT4 = 3.73
GT5 = 4.10
GU4 = 3.08
G80 means it has limited slip
If none of those match, Google GM RPO codes
