The Serpent SER402194 is an RC antiroll bar identified as 1.2 X26 and specified for the Medius X26 steel EP kit (SER400052). As a direct-fit sway bar, it is used to adjust lateral roll stiffness between the chassis sides on electric scale cars.
The 1.2 X26 code describes diameter and length characteristics that determine relative stiffness versus other bar options. Changing to this bar modifies how quickly the chassis transfers load side-to-side when cornering; assess changes with measured testing and compare behaviour before and after swaps.
Installation is standard for kit sway bars: the bar sits in the chassis mounts and connects to the suspension linkages, replacing the existing component. Check fitment to mounts and linkage geometry prior to final tightening, and ensure free movement through full suspension travel. Inspect steel parts and fasteners regularly for wear or loosening after runs.
Use this antiroll bar as a simple mechanical tuning step to refine roll-stiffness balance on the Medius X26 steel EP chassis.
