Final Gears

Does anyone know what my final gear ratios are in my 84 4x4 S-Blazer Tahoe model, 2.8L auto? And what ratio works good in these trucks for on road and off-road use? thanks

Re: Final Gears

an 84 blazer stock should have a 3.42 gear ratio. that gear is great off-road and on-road if you have the stock or the same size as stock tires on it. anything bigger than the factory tires and you will notice a power loss. the bigger the tires, the bigger the ratio needs to be...

e.g.~
31 in. tires--3.73
33 in. tires--4.10
and so on...

Taken from S10Extremist.org
GM was nice enough to put a dash plaque (laminated paper inside glove box) in our vehicles that lists a bunch of codes... If you see any of the following codes listed then you have the axle ratio specified...
GM8 = 2.56
GU2 = 2.73
GU4 = 3.08
GU6 = 3.42
GT4 = 3.73
GT5 = 4.10
HO4 = 4.11
G80 = Posi

The 2.56 was a 2wd option only in 82 while the 2.73 option was only an option in 82-83... An interesting thing to find was the 2.73 was an option even on the 4wd in 83...
