The JR-TRX418-GU body post mount is a precision aluminum upgrade for the Traxxas TRX-4 platform. Its compact gun metal profile gives a stable mounting point intended to improve body seating and reduce unwanted movement while crawling.
Made to complement TRX-4 body mounting standards, this aftermarket mount replaces the original post arrangement to deliver more consistent body positioning and better clearance management when negotiating obstacles.
Fitment is aimed at builders comfortable with TRX-4 body hardware: the mount installs in place of the stock post and uses the vehicle's existing attachment points. The part is a non-invasive upgrade that leaves suspension and drivetrain settings unchanged.
From a tuning perspective the mount is a simple way to control body height, cut down on trail-induced rattles, and provide a robust anchor that stands up to repeated impacts. The aluminum construction favors stability over weight savings for scale-focused setups.
