      Unless you damage it, you don’t have to replace it. At least on a Gen II.

      I recall 2003 (and 2004?) Having balanced bolt issues.

      The 03/04 from factory is known for loosening up and the balancer spinning. Add lock right to the crank bolt. If you are inclined, Roe Racing sells a crank pin kit.

      The 2005/2006 bolt is bigger and will not fin in a 2003/2004 crank.

      Are some of the bolts in the 2003 Model Year the old, larger style? I note that the part number in the parts list is only different for the 2004MY. The Parts lists for 2002, 2003, 2005 have the same old larger bolt part # listed

      Thanks everyone. I will put it out and put some lock tight on it. I hop to have the viper running again soon.

      Late to join the thread I know….I was lucky, my bolt and balancer fell out in my driveway! Definitely an issue on 2003 vipers. Our year had a larger diameter, shorter bolt with a different torque spec than later years. I would definitely pin it. I upgraded to ATI at the same time. I would not trust anything other than pinning if you are boosting it.

      Does the balancer bolt have to be replaced? I just want to make sure the bolt is not one of them use once and throw away type bolts.
