The 3Racing SAK-A567D Gear Differential Gasket is supplied for the Sakura Advance 21 chassis to provide a reliable sealing surface that supports consistent diff oil retention and cleaner internals. Consistent sealing is key to predictable diff behaviour during setup changes and track conditions.
Designed with competitive use in mind, the gasket contributes to stable differential performance by maintaining the intended lubricant environment. This helps keep finger-tight preload and tuning adjustments predictable between runs.
The gasket is manufactured to match the Sakura Advance 21 differential housing profile for direct replacement swaps. For race teams, confirm mating surfaces are debris free and install as part of regular diff service intervals to avoid oil migration and inconsistent diff action.
