Dana Spicer 513376 5.29 Ratio Ring Gear & Pinion Kit
The Dana Spicer 513376 Gear and Pinion Kit is a genuine heavy-duty differential ring-and-pinion service gear set designed for select Dana Spicer tandem drive axle applications. Featuring a 5.29:1 axle ratio with a 37-tooth ring gear and 7-tooth drive pinion, this matched gear set is engineered to restore proper final-drive reduction, torque transfer, and differential performance during axle rebuilding or repair. Dana lists the 513376 for DSP40, DSP41, DS344, 404, 405, and 454 axle families.
The ring gear and pinion work together as the primary reduction gear set inside the differential. The pinion receives rotational power from the driveshaft and transfers it through the larger ring gear to the differential carrier and axle shafts. With its relatively deep 5.29 ratio, the 513376 is suited to applications where strong low-speed pulling capability and torque multiplication are more important than high road-speed gearing.
Dana manufactures Spicer gearing using tightly controlled machining, heat-treatment, and finishing processes. Dana specifically notes the use of three-axis face hobbing, controlled heat treatment, shot peening, and a chemical gear finish intended to promote smooth initial operation and reduce noise, vibration, and harshness.

Gear Components
Dana service literature identifies the traditional components for the 513376 5.29 gear set as:
- Ring Gear: 129734 / 130196 depending on catalog revision/application

Dana’s heavy-axle quick-reference literature identifies 513376 as the 5.29-ratio service gear set with a 37/7 tooth combination.
Heavy-Duty Dana Drive Axle Applications
The 513376 is used in Dana/Spicer heavy-duty drive axles from the DS/DSP family, including several generations of 40,000-lb-class tandem axle designs. These axle families are commonly found in Class 8 tractors, vocational trucks, dump trucks, refuse vehicles, mixers, and other applications where high drivetrain torque is required.
The 5.29:1 ratio means the pinion must rotate approximately 5.29 times for one rotation of the ring gear. This deeper numerical ratio provides increased torque multiplication at the wheels, making it particularly useful in heavy-load, vocational, severe-service, and lower-speed applications.
