This Serpent 440157 pin is a 2x6.2mm RC spare intended for the Serpent Mini Spyder chassis. It replaces worn or lost retention pins used in linkage points and drivetrain connections to preserve correct component positioning.
Pay attention to fit and alignment when swapping these small pins; clean mating holes and remove debris to prevent unwanted play. The nominal 2x6.2mm size secures link ends and small joint assemblies commonly fitted on Mini Spyder RTR setups.
After the first outing and following heavy impacts, recheck pin seating since correct retention directly influences toe, camber response, and drivetrain alignment at scale.
Compatible with Serpent Mini Spyder Monster truck RTR EP (SER440001).
