Re: ZR2 3.73 Rear End Gear Question????
Early ZR2's did not come standard with the G80 Gov-lock. Sometime around 97 or 98 this changed, and from then on all trucks were so equipped stock. As someone mentioned above, check the sticker in your glove box... you'll see G80 as one of the many codes listed. The G80 does not kick in until one tire is spinning quite a bit faster than the other (I've heard 100 rpms, but I'm not sure on that), so its quite possible to feel one side pulling hard off the line.
