Specifications
The TDA2234K271 Side Gear from CCC Parts is a direct aftermarket interchange for Meritor/Rockwell 2234K271. Side gears sit inside the differential carrier, spline to the axle shafts, and engage with spider gears to allow speed difference between wheels during turns. This gear is precision-machined from hardened steel to handle high torque loads common in commercial trucking. The 2-1/4" 23-spline profile ensures correct axle-shaft fitment and stable contact patterns. Replacing a worn side gear during a rebuild helps reduce chatter, restore backlash control, and extend the life of the entire differential assembly. Sold by Wofford Truck Parts.
