S14 ABS with RB25 5-Speed (Syko mounts) Carbon Fiber Shaft. This is our single shaft conversion for the 240SX platform. The shaft features larger, replaceable and greaseable u-joints and can handle about 650WHP. By removing the factory 2-piece shaft and installing a single shaft the car will feel more responsive due to the fact the hanger bearing is not moving up and down during acceleration. Available for most popular motor/trans combinations, if you don’t see yours listed, custom shafts are also available.
