Final Drive Gears

Final Drive Gears

Final drive gears determine the overall multiplication ratio between the engine and the driven wheels, with the ring and pinion gear set inside the differential carrier providing the final stage of ratio reduction that translates transmission output into the torque and speed delivered to the axle shafts. Changing the final drive ratio is one of the most effective ways to tailor a vehicle's character for a specific purpose, with numerically higher ratios improving acceleration and towing torque at the cost of higher RPM at cruising speeds, while numerically lower ratios reduce cruise RPM and improve fuel economy at the cost of off-the-line acceleration. Performance builders choose gear ratios based on the engine's power band, the transmission's gear spacing, tire diameter, and the primary intended use whether that is drag racing, road course, towing, or overland travel. This collection covers ring and pinion gear sets for domestic trucks, muscle cars, and import performance applicati...
