Not really. A lot of those OBS trucks had 3.42's. Look at the gear gode in the glove box. I don't remember exactly what they are but its like g4 or g6 or something to that effect.

Guess my 95 that my grandpa bought new wasn't a true one then cause it had 3.42s. Said Z71 on the bed too.

WRONG, but good try.

Now, in the new body trucks 99-03 they were optioned only 3.73 or 4.10.

Here are the gear codes though for the OP to identify an axle. Those ten bolts are quite pricey for the **** piles they are. I would look for a 6-lug semi-float 14 bolt to swap in.

GT4
Rear Axle: 3.73 Ratio

GT5
Rear Axle: 4.10 Ratio

GU4
Rear Axle: 3.08 Ratio

GU6
Rear Axle: 3.42 Ratio

G80
Rear Axle: Positraction

HC4
Rear Axle: 4.56 Ratio

HC7
Rear Axle: 5.13 Ratio

If it was purchased new that way it probably was a Z71. There is also a RPO code in the glove box to check if it was optioned Z71 as well though.

WRONG!....A lot of people get z71 facts fudged up. I have had them with 3:42, 3:73, and 4:10. They also made tahoes that were z71 without all the body color crap on them.

My bad guys. ALL Z71s had GT4 & G80 as standard equipment, but other ratios could be special ordered. So 95% (or more) of them are probably 3.73s, but not all
