The Arrowmax BB DJC Set upgrades the Serpent X20 drivetrain by swapping out blade-style shafts for ball-bearing double jointed cardan shafts, cutting friction and improving drivetrain efficiency. This change helps the chassis deliver power more smoothly to the wheels.
Ball-bearing DJC components lock into the drive cups with minimal slack, reducing free-play and promoting consistent rotation under load. The tighter fit improves both component longevity and on-track response during acceleration and turning.
These driveshafts are manufactured for a direct fit on the Serpent X20, allowing a simple install with no major trimming or mods. They are a sensible upgrade for drivers seeking better traction and cleaner drivetrain behaviour.
