The "Third Generation Camaros" require mount points on the differential for the torque arm, trailing arm links, spring pads, panhard rod and shocks. Many aftermarket options exist with all of the appropriate mount points.

The most common GM unit for the 1982 to 1992 Camaro is the Saginaw style 10 bolt Chevy differential.

  • 1982 to 1984: 7.5 inch ring gear, 26 spline axle
  • 1985 to 1989: 7.625 inch ring gear, 26 spline axle
  • 1990 to 1992: 7.625 inch ring gear, 28 spline axle
    PN 26010268 (drum brakes)
    PN 26028692 (disk brakes)

The "Third Generation Camaros" were available with both rear drum brakes and rear disk brakes. The hand brake is slightly different for each. The throw (distance of pull) is greater for the disk brake. This was achieved by utilizing a different hole position where the end of the cable connects.

Any change from a drum brake system to a disk brake system will require a change to a disk brake based master cylinder and proportioning valve as well as the aforementioned handbrake lever.

Full Floating Axle Conversion:

Performance brakes manufacturer Baer supplies a full floating axle "Baer Tracker" conversion kit for Ford 9" and Dana 10"/12" units to provide superior capability to handle lateral forces. Traditional flanged axle designs employ a single axle bearing to support both the weight of the vehicle and lateral forces. During cornering, the flange is levered by lateral forces causing deflection and bending. This often causes the brake rotor to press against the brake pad and a return push of brake fluid.

A full floating axle conversion allows the axle to only provide drive power to the wheels. The support of the vehicle weight and lateral forces are handled by the "Baer Tracker" conversion unit's strudy steel spindle unit. It will improve longevity of the bearings and improve braking predictability.

Also see our brakes page for more info.

Torque Arm:

The third gen Camaro uses a torque arm to position, stabilize and control differential twist under acceleration and braking. This arm is attached at one end to the differential housing by two large bolts and at the front-end to a mount on the trasnmission tail housing. The front-end mount is a metal mount which clamps upon a rubber bushing which encapsulates the torque arm. There are three styles for the third gen. Energy Suspension sells a durable polyurethane replacement:

  • 1982-1983: 3.1110
  • 1984-1992: 3.1111 (lips facing away from driveshaft)
  • 1984-1992: 3.1112 (lips facing towards driveshaft)
Given that the OEM rubber bushing dissolved from the transmission oil and heat, the polyurethane bushing seemed like a worthy upgrade. It is noeworthy that this bushing required trimming to make it fit the GM torque arm.

And of course don't forget to fill the differential with gear oil. Shown here are two viscosities of Liqui Moly synthetic gear oil.
