Serpent 401122 - 3.15mm Tungsten Carbide Diff Balls  [SER401122]

Durable Tungsten Carbide for Touring Diffs

Give your 1/10 touring car diff a durability boost with Serpent 401122 tungsten carbide balls. These 3.15mm balls are made from hard-wearing tungsten carbide to resist surface damage under heavy loads. The upgrade helps minimise wear on rolling components and keeps your differential performing consistently over many running sessions.

Resistance to Deformation

Tungsten carbide is chosen for its ability to resist deformation and maintain a round profile under stress, reducing problems like flat spotting. Fitting these balls supports smoother power transfer through the diff and lowers the need for frequent component swaps.

Ready for Race Day

Whether refining setup for club races or regular track practice, these tungsten carbide balls help keep differential behaviour predictable. That predictability makes it easier to dial in handling and focus on driving performance rather than drivetrain repairs.
