The Serpent 500897 rod end is a replacement component intended for RC dampers that take 13mm style rod ends. Supplied as a +3 offset set of 4 pcs, it is used where a slightly increased rod-end projection is required to modify linkage or preload settings.
Installation uses conventional damper servicing steps: remove the old rod end, fit the +3 unit and verify correct thread engagement and smooth articulation. Typical workshop tools such as hex keys and pliers will suffice; this is an aftermarket part for suspension tuning on scale models.
As a tuning tool, the +3 option changes the effective link length and can affect roll center and shock leverage. Make incremental changes and record handling effects to build a setup baseline.
