can you extract what rear end ratio is on my truck via the serial number 1gtek19v8z347602

That's not a VIN, a VIN has 17 characters and there are 16 there. But the answer is yes, with a VIN.

Call your local gm dealer service department, and they can get it from their gm site

look in the glove box there should be a silver coloured sticker with a bunch of 3 digit build codes. the codes that begin with G are for the rear axle ratios. GT4 = 3.73 GT5 = 4.10 GU5 = 3.23 GU6 = 3.43 G80 = locking rear diff G86 = Limited slip rear diff hope this is helpful

Thank you, helped, never knew about that code sticker.
