Introducing our long awaited S2000 3.50" Diameter Aluminum CV driveshaft. On the Front (Transmission side) we've incorporated our proven 108mm CV design that has also been lightened to shed extra weight. To adapt the rear we've made an all new Billet Aluminum adapter plate/flange with a genuine Spicer solid 1310 series U-joint. This entire combo comes in at a very impressive 18lbs. While very close to stock weight, the vast improvements in strength and design lead to unparalleled high horsepower and high stress performance. Using our new internally dampened design to soak up gearbox and differential noises, there are no compromises for street driven comfort!
