The Dana Spicer 37069 or 037069 side gear is listed in our parts manual for three units: the DS/RS 340-402 Tandem Drive Axle (item 18 forward, item 14 rear), the DS402 Single Reduction Tandem Axle (item 18, forward tandem axle differential carrier) and the DT/RT 340-402 Two-Speed Tandem Axle (item 40 forward double reduction, item 38 rear). Each side gear drives an axle shaft to a wheel. When one wheel meets less resistance, the spider gears rotate so that side runs faster than the other, letting each wheel turn at its own speed through a corner. A genuine Dana Spicer part from Pro Gear and Transmission.
