Differential Gear Spacers (4pc) - Compatible w/ X-Maxx & XRT

Function & Usage
Replace the internal differential gear spacers in your Traxxas XRT or X-Maxx differential with these 7075-T6 aluminum spacers from GPM. These small spacers sit behind the spider gears on the spider gear shafts and help maintain proper gear positioning, backlash, and thrust support inside the differential. Maintaining consistent spacing helps keep the spider and output gears properly engaged across the full tooth face, especially under the high drivetrain loads of 8S power.
