I've had fairly good luck with the stock halfshafts until recently . I have well over 300 passes on the stock shafts without a half shaft failure until recently . The last 2 weekends in a row I've gotten one . I broke the driver side last weekend and the passenger side this past weekend . It seems since I installed the DFX clutch it has found the weak link in my car . Oh well no more playing around I've got a solid axle that's going in either this week or next .
