Differential Locker Spool: Traxxas Magnum 272R Transmission (HRATEDR125)

Differential locker spools are aftermarket upgrades for Traxxas RC vehicles, designed to lock the differential for improved traction and more predictable power delivery on challenging surfaces. Two variants are available: one tailored for Traxxas Magnum transmissions and another compatible with popular Traxxas models such as Slash, Bandit, Rustler, and Stampede.

Built for durability, these spools help transfer power more consistently by locking both wheels together, reducing wheel spin and improving handling during acceleration and cornering on loose or rough terrain.
