3.43 Automatic and 3.73 Manual
I believe it's 3.43.
It depends on the gear ratio and rear tires (automatics had 3.42 and Manuals had 3.73's) But as an example. My 1979 Z28 with 600cfm carb and cheap headers and the stock 3.42's in the rear buried the speedo at 130mph and the rpms were still climbing.
The 1982 Camaro Z28 typically came with a rear axle gear ratio of 3.42:1 as standard. However, some models could be equipped with an optional 3.73:1 gear ratio for enhanced performance. These ratios contributed to the car's acceleration and overall driving dynamics, aligning with the performance-oriented nature of the Z28 trim.
most Z's had the 3.42 gear ratio.
3.42
yes the rear end is the same from 82-2002 the breaks and gear ratio's are what makes the difference
The fourth generation General Motors F-Body (Camaro/Firebird) was offered in multiple rear end gear ratios. These included 3.02, 3.42, and 3.73.
I think it varied on which engine The car originally came with, but mine is A 1992 Z28 with the 5.7 TPI and I have 3.42:1 gears ratio, and my 1987 Iroc-z with The 5.0 carbureted has 3.23:1
My RPO says my 1996 Z28 has a 273 Posi ? Is that for real ? It doesn't feel like 273....feels much more like 373 or 342 !
Checking the build code, GU2, shows the rear gear is 2.73 and not 3.43 as noted with the six speed on most web sites. 3.43
80/90 gear lube
It might. Depending on width and bolt patterns. But the gear ratio maybe wrong. Consult a locak mechanic about checking into your gear ratios
