HRSXRT93511R - 35t/11t HT Helical Diff Ring/Pinion Rear Gear TRA XRT X Maxx

This helical rear differential ring and pinion gear set is engineered to upgrade the rear drivetrain of Traxxas XRT and X-Maxx models with smoother, quieter operation. Featuring helical tooth geometry, the gears distribute load more evenly than straight-cut designs, reducing noise and vibration while improving traction and drivetrain efficiency. Precision machined from hardened steel, the 35T ring and 11T pinion resist wear under high torque and aggressive driving. The direct replacement design fits into the stock rear differential without modification, maintaining correct gear mesh and alignment.
