This product is a gray aluminum center driveshaft designed to improve strength, durability, and power transfer in high-performance RC drivetrains. The aluminum construction reduces flex compared to stock composite shafts, helping deliver smoother acceleration and more consistent drivetrain response. It is built for precise fitment and reliable operation under demanding conditions such as high-power setups and aggressive driving. This part is compatible with Traxxas 4x4 platforms including Slash 4x4, Rustler 4x4, Stampede 4x4, and Hoss 4x4, depending on vehicle configuration and drivetrain setup. It is an excellent upgrade or replacement option for drivers looking to enhance durability and performance using quality components from Traxxas.
