The GPM rear gear cover for Traxxas XRT 8S is constructed from 7075 aluminum alloy to provide a stiffer mounting surface and a durable anodised finish. The part retains OEM attachment points while adding an extension groove to accommodate larger or additional bearings, improving axial support and reducing shaft deflection or cracking associated with the factory component.
The cover accepts 8x19x6mm bearings on an 8mm shaft to increase drivetrain rigidity and service life. When combined with XRT033TS and XRT035TS large gear sets, the assembly permits a four-bearing fixation for enhanced bearing distribution and load handling.
