This shaft uses an Carbon fiber front and rear shafts with a specially designed hanger bearing and bracket that eliminates the violent hanger lag that occurs when power is put through the factory shaft. The weight on our driveshaft is approximately 14.55kg plus the weight of the hanger bracket which is 0.45kg (factory shaft is about 19.1kg). This driveshaft uses only 1 hanger bearing, instead of the 2 on the factory shaft and features greaseable / replaceable u-joints instead of the non-serviceable type on the factory shaft. We also include necessary hardware making this a direct bolt-on. More responsive, smoother transfer of power and capable of over 900HP, this driveshaft will stand up to anything you want to put to it.
