The Cometic AFM differential cover gasket for GM 8.875in, 12-bolt passenger car applications uses a nitrile-synthetic rubber bonded to an aluminum core for durable sealing. AFM retains torque, recovers up to 85%, and resists temperatures over 205°F. The asbestos-free material typically does not require sealants or re-torquing, simplifying installation for service and maintenance.
