Radtec RAD-BEL-10002 is a low friction white front drive belt (S3M510) built to enhance drivetrain smoothness in Serpent 4X stock configurations. The reduced surface resistance helps the car accelerate and respond more predictably.
By minimising internal resistance, this Radtec belt supports steadier power delivery and better belt tracking. It is a practical upgrade for drivers chasing consistent handling across runs.
The belt installs into the Serpent 4X routing without special tools or chassis changes. Its snug fit keeps belt tension stable under race conditions.
