This Serpent 440157 pin is a 2x6.2mm spare built for the Serpent Mini Spyder chassis layout. It replaces small retention pins in linkages and drivetrain connections to keep suspension and drive components positioned correctly.
Focus on hole cleanliness and exact fit during replacement to avoid play. The nominal 2x6.2mm sizing secures small joints and link ends found on typical Mini Spyder RTR configurations.
During tuning routines, recheck pin seating after the first test run and following heavy hits, since proper retention affects toe, camber response, and overall drivetrain alignment.
Compatible with Serpent Mini Spyder Monster truck RTR EP (SER440001).
