Spicer offers two ring and pinion types. Spicer Premium Ring & Pinion Gears are the same as used in OE applications. Process-controlled machining, heat treatment, face hobbing, shot peening, and lapping operations provide a smoother, quieter ride and years of trouble-free service. Spicer SVL Ring & Pinion Gears deliver quality and performance that meets or exceeds most popular aftermarket products. SVL Gears are available for Dana, Chrysler, GM, and Ford axles.
