I purchased this chain from a forum member who claims it's a c5r chain. from the looks of it I don't feel like this is the infamous c5r chain but I had no earlier experiens with it at all. Attached are pictures of it and next to the stock ls2 chain.

Please advice if this is the true one as I'm really afriad to put it in my LS3.

Thanks.

 

says jwis right on the link which is the maker of the c5r so yes i would say that is one

 

Yep, but is it really thinner than the ls2 chain ?

 

There is another JWIS chain that sells for like $70-80 that is not the C5R chain. I don't know if that's what you got or not. Was the packaging open?

 

Yep its only the small bag you see. How do I know if this is the "cheap" JWIS ?

 

C5R chain is much beefier & tighter than the LS2 chain.
Do a google search & see what you can find, even on Tech there's been people wanting to know, have a search.
The chain should really be used with the right gear set...'hex a just' to get the full benefit.
