This driveshaft is rated to 650WHP and a top speed of 155MPH and is not recommended for use above this speed. This aluminum driveshaft is 3" diameter and your vehicle may require some minor modifications to the driveshaft tunnel in order to ensure proper fitment. Make sure there is at least 3/4" clearance around the driveshaft before use, and that the differential bushings are not worn as this can cause damage to the driveshaft. Damage caused by improper fitment will not be covered under warranty.

ATTENTION 2003-2007 Subaru WRX and STI owners. We have had some warranty issues regarding damaged driveshafts (aluminum and carbon fiber). After some research on our part, we found a common denominator that the driveshafts were damaged 11-12 inches from the differential. The culprit it turns out is either subframe, differential, or transmission mounts/bushings failing and allowing movement of various drivetrain parts resulting in the driveshaft striking the rear brace. As this is not an issue with Driveshaft Shop parts but a maintenance/age issue, we will not be offering warranty for this issue any longer. Regardless if you have one of our driveshafts or not please be aware of this issue for the health of your vehicle and its parts.
