Specifications
The SPX127645 Output Side-Gear from CCC Parts is an aftermarket replacement for the OEM Eaton/Dana-Spicer 127645 differential side gear. It is engineered for the DS404 series and related DA/DD344/405/454 forward drive axles, specifically versions produced before June 2008. Machined from high-strength steel and finished for corrosion resistance, the gear features a 34-spline inner bore and 14-tooth outer profile to mesh correctly with spider gears. Installing a fresh side gear during a differential rebuild helps maintain correct backlash, improve traction balance between axle shafts, and extend carrier life. Sold by Wofford Truck Parts.
