Are there pinion gears in a Camaro axle carrier?
Are there pinion gears in a Camaro axle carrier?
The pinion gears used in COPO carriers are actually the same as those used in standard open carriers. The clutch plates are the same for the COPO and regular 4-series posi units, with 18 plates (9 per side). There are some other parts that are specific to the COPO carriers.
Where is the differential carrier in a Camaro?
The differential carrier case (often commonly referred to as the carrier) in this gear train is located inside the center section of the axle housing (differential carrier and axle tube assembly). It transfers motion from the driveshaft to the axle shafts using a ring gear and pinion shaft.
Can a Camaro axle be converted to a Posi?
(In 67-68, it appears that positraction was not a requirement with the 3.73 ratio for non-Z28 cars.) If an axle has an open carrier, then it can be converted to a posi by installing a posi carrier of the same series. The pinion does not have to be removed, but the ring gear does have to be swapped over from the open carrier to the posi carrier.
What was the axle ratio of a 1967 Camaro?
Specifially, in 1967, the 2.73 posi axle was of such low volume that all 2.73 axle ratio with positraction were 12-bolt axles. This was independent of other options on the car. Even some 6 cylinder cars have been observed with 12-bolt 2.73 posi axles.

What should I do if my Camaro differential is broken?
Remove the ring gear bolts and tap the ring gear off the carrier with a soft faced hammer if you plan on preserving the gear. Tap it off evenly around the perimeter; otherwise it will get damaged or at least get caught up at an angle. If excessive wear or cracks are discovered, the carrier must be replaced; it’s not worth rebuilding.
What’s the gear ratio for a 12 bolt Camaro?
For the 12-bolt: 2.73 and 2.56 gears use a small carrier; 3.08 through 3.73 gears used the medium carrier; and the 4.10 and numerically higher gear sets used the large carrier. The higher (numerically) gear ratio has a smaller diameter pinion head, so the ring gear has to be closer to the centerline of the pinion.
