Traxxas 6788 front differential assembly for 4×4 is a rugged drivetrain component designed to transfer power smoothly from the transmission to the front wheels while allowing them to rotate at different speeds during cornering. Built to factory specifications with durable gears and housing, this differential helps maintain traction and stability in a variety of driving conditions, from high‑speed runs to off‑road terrain. It installs easily using standard mounting hardware and helps restore proper drivetrain performance if your original front differential becomes worn or damaged.
