S14 240SX with JZ CD009 6 Speed With Collins Adapter ABS Steel Shaft. This is the ISR one piece driveshaft conversion for the 240SX platform. The ISR Performance driveshafts are designed to be the perfect fit for your conversion swap when using the corresponding ISR swap mounts. The shaft is built using Dana/Spicer solid high performance u-joints. By removing the factory 2-piece shaft and installing a single shaft the car will feel more responsive due to the fact the rubber carrier bearing is not moving up and down during acceleration. Please Note: Whether or not the car was equipped with ABS from the factory please verify if you are using a non abs or abs differential to determine which driveshaft you need. The change in differential will change the length of the driveshaft. Be sure to check your vehicle before ordering. This shaft is only guaranteed to fit if using ISR Performance swap components.
