The Serpent 402000 Magnesium Gear Diff O-Rings are intended for hobbyists maintaining or tuning their differentials. These 20x1mm magnesium O-rings help secure a tight seal to support smooth drivetrain response in touring cars.
Using the correct O-ring reduces the chance of seal-related issues and keeps tuning consistent between sessions. Serpent 402000 components are specified to meet the demands of regular maintenance and track use.
