GPM Racing Traxxas XRT 8S Rear Bumper Mount for Traxxas 1/6 4WD XRT 8S-78086-4 (XRT040R)

Engineered rear bumper mount for XRT 8S

This aftermarket rear bumper mount is a precision moulded replacement part intended to secure the rear bumper on TRAXXAS XRT 8S platforms. The component focuses on consistent fixation and impact tolerance rather than appearance, using a reinforced thermoplastic formulation to reduce the risk of cracking under typical off-road loading conditions.

Installation follows the factory mounting points: the mount aligns to the existing chassis holes and is fastened with the supplied long and short pins plus stainless washers and lock nuts. Careful alignment and confirming full pin engagement reduce lateral play and help ensure repeatable bumper position during heavy use.

From a workshop perspective, this part is a service and durability component rather than a tuning element; it maintains bumper alignment so rear protection and body mounting remain stable throughout repeated runs.
