Dana 30 Reverse Ring & Pinion | Yukon Gear & Axle

Dana 30 Reverse Ring & Pinion High performance Yukon Ring and Pinion replacement gear set for Dana 30 Short Pinion.

Dana 30 Reverse Ring & Pinion set transfers power from the driveshaft to the axles. The pinion gear is mated to the driveshaft via a yoke and universal joint and drives the ring gear. The ring gear is mounted on a carrier assembly which in turn drives the axles and wheels. Different gear ratios are desirable for different applications and usage. Gear ratio is calculated by dividing the number of teeth on the ring gear by the number of teeth on the pinion gear. The higher the number, the lower the ratio: a 5.29 gear has a lower ratio than a 4.10 gear. With a lower gear ratio the drive shaft (and thus the engine) turns more for each revolution of the wheel, delivering more power and torque to the wheel for any given speed. Lower ratios are generally desirable when going off-road. Higher ratios are better for freeway driving since they run at lower RPM’s and offer better fuel economy.
