The GPM TXM8011 differential case is CNC-oriented hardware intended to increase chassis stiffness and improve heat transfer away from the gearset on Traxxas X-MAXX 8S machines. The unit reduces case deformation under torque, protects gear bearings, and supports repeatable gear mesh during high load cycles. Available in six finish options, it is a direct-swap upgrade for TXM 8S configurations where durability and thermal performance matter.
