This is an optional Serpent 811 Plus4 Chassis Upgrade Set. Serpent has introduced this optional part for the gas-powered Cobra buggy, the Plus4 Chassis-set. This chassis is standard in the 2.1 Cobra Buggy. 


  • The Plus4 Chassis: The hard anodized chassis is 4mm longer in the rear, creating a more stable rear end, vastly improving handling on tracks with short bumps and rough surfaces while still maintaining performance and handling on flatter surfaces and smooth transitions.
  • Included Longer Aluminum Rear Brace: the longer aluminum brace also helps to make the rear end more stable.  The shorter nylon or aluminum version can also still be fitted.
  • Included Longer Rear Central Shaft: To suit the longer chassis a longer rear central shaft is included.
  • No other modifications needed!
