These 89.5mm front universal swing shafts are crafted from high-strength hardened steel, providing superior durability and smooth power transfer for the Kyosho MP9/MP10 drivetrain. Engineered for the front axle, they replace traditional dogbones to offer increased articulation and consistent performance during aggressive cornering and jumps. This upgrade is essential for maintaining drivetrain integrity and responsiveness in high-speed racing scenarios.
