Demand genuine Spicer. Made in the USA and complete with all the components needed for the repair. Dana design, engineering, testing and manufacturing processes all work in conjunction with one another to ensure unparalleled performance that non-genuine parts simply cannot deliver. Spicer gearing offers the easiest possible set-up, a quieter ride and strength that cannot be beaten. All gears go through a rigorous production to ensure quality. Statistically controlled heat treatment optimal hardness. Three axis face hobbing reduces noise, vibration and harshness while delivering the smoothest possible ride. Shot Peening doubles fatigue life by shooting micro beads at the root of the tooth. Gears are luberized by adding a chemical finish to remove the break in period other aftermarket gears require.Features:
Superior Metallurgy: Ensures more consistent, higher quality product
Hobbed and Shaved Gearing: Provides optimal mating to minimize stress and maximize life
Precision heat-treating and shot-peening delivers consistent quality, enhanced life by reducing residual stress doubling the fatigue life of the gear
High-grade steel for maximum durability
Differential Identification Guide
To order the correct ring & pinion, it's crucial to know the differential type and gear ratio on your vehicle.
Next, determine the gear ratio on your vehicle using one of the following methods:
Count The Teeth: Divide the number of teeth on the ring gear (big gear) by the number of teeth on the pinion gear (small gear). If you have 37 teeth on your ring gear and 12 teeth on your pinion gear, you have a 3.08 Gear Ratio (37 ÷ 12 = 3.08).
Verify Through A Dealer: Verify the ratio using your VIN number. This will only be accurate if the differential has not been previously modified.
