This matched gear set drops in as a direct-fit replacement for a long list of GM cars, trucks, vans and SUVs, and is cataloged for both front and rear differential applications — including the 1973-1975 Buick Apollo, 1971-1989 Buick Electra, 1968-1981 Chevrolet Camaro, 1968-1996 Chevrolet Caprice, 1999-2013 Chevrolet Silverado 1500 and 1995-2013 Chevrolet Tahoe, plus many more (157 applications in all — see the Buyer's Guide tab for the full list).
- Ring and pinion set: the pinion gear meshes with the ring gear to carry driveshaft torque into the differential and turn it toward the axle shafts.
- Final drive ratio: the gear pair sets the ratio that gears engine rotation down to the axle.
- Front or rear use: cataloged for front and rear differential applications on the listed vehicles.
- Replacement job: designed as a direct-fit replacement for worn or damaged original ring and pinion gears.
Signs the gears may need attention include a whine or howl from the differential that changes with vehicle speed; if worn ring and pinion gears are the cause, this set replaces them. Diagnose the noise before ordering, since other driveline parts can produce similar symptoms.
