Heavy Duty Corvette driveshaft couplers are a must for all C5 & C6 Corvettes competing in motorsports events. Heavy duty driveshaft couplers will eliminate damage to the torque tube caused by the OEM rubber coupler having a catastrophic failure and coming apart. Recommended to be used with Zip Corvette's 2001-2004 Carbon Fiber Driveshaft or 2005-2012 Corvette Carbon Fiber Driveshaft. Not recommended for street use
