Spicer 708125-4 Dana 60 Ring & Pinion Gear Set 3.73 Ford E-Series Install Kit

The Spicer 708125-4 Differential Ring & Pinion Kit is a genuine Spicer replacement gear set for Dana 60 rear axles requiring a 3.73:1 ratio. The matched 41-tooth ring gear and 11-tooth pinion provide the factory 3.73 ratio and are designed for the 4.10-and-down carrier.

This is an installation-kit configuration, not simply a loose aftermarket gear pair. Dana confirms the ring gear, pinion gear, pinion nut and installation kit are included. Genuine Spicer gears are manufactured to Dana OE specifications and use matched gear geometry intended to provide proper strength, durability and quiet operation.

A particularly useful application for this part is the Ford E-Series/Econoline Dana 60 rear axle. Denny's identifies 708125-4 for 20012019 Ford E-Series vans with Dana 60 C-clip rear axles, while Spicer's own Ford axle documentation shows the 708125-4 used across multiple standard and Trac-Lok Dana 60 configurations. Exact axle/BOM should still be verified before purchase.
