For the hardcore racer, Jato has available these trick metal driveshafts. They concentrate the mass for less overall rotational mass than the stock Jato driveshafts. This results in even quicker acceleration. The outside U-joint is lubricated and sealed by a rubber boot to protect it from dirt and grime. The U-joint pins are held captive by the ball bearings so you never have to worry about losing a pin. Computer-aided design permitted Traxxas engineers to design these shafts to handle the extreme articulation generated by Jato
