Traxxas 9584R Mount Center Differential Carrier Red Monster Trucks The package includes 1 pairCenter differential carrier mount machined from 6061 T6 aluminum with a red anodized finish. The mount locates the center differential in the chassis and holds it square to the front and rear driveshafts. Any flex or misalignment here loads the driveline unevenly and accelerates wear on the diff and shafts, so aluminum is a worthwhile upgrade on a 6S truck. Fits: Traxxas Sledge (95096 4). Direct replacement for the factory center differential mount.
