S13 ABS with KA24/SR20 5-Speed Aluminium Driveshaft. This is our steel 1-piece replacement shaft for the 240SX platform. This shaft is about 5lb less than the factory 2-piece and will give the car a faster throttle response due to the fact the hanger bearing is not moving up and down during acceleration. A less expensive alternative to our Aluminium shaft, it has been suggested by a few of the drift cars that we sponsor the steel shaft breaks the tires loose quicker than the Aluminium. This steel shaft will give you most of the benefits of the Aluminium shaft, without the cost.
