Hi all. I recently bought an Aug 2015 Challenger Hellcat and have been reading a bit about pinning the crank pulley to avoid slipping but cannot for the life of me understand why this would need to be done on a reasonably new car. Anyone know the story behind this and why it is still an issue?

Is it that common for crank bolts to be incorrectly torqued at the factory or for them to loosen on a stock car?

Crank pinning kits are reasonable cheap but I just don't fancy the idea of ripping out the entire front end, drilling and putting it back together. I also have an aftermarket warranty with a £7k limit per job but if I got slip, it would be an engine replacement job and they wouldn't cover it.

Any ideas if one should do this? Is the chance of failure high? I don't plan on modding.

I don't think that there are enough owners in the UK to get a good idea of whether or not it's an issue & if it affects standard cars or just ones that have been modified. I'm sure that there are some US forums that might shed a bit more information.
A quick Google search says to me that it's more an issue with supercharged engines which makes sense as the increased load will spin the damper. Most of us here have old school stuff that has a keyway to locate the damper on the crank.
