How much stronger is a LS2 timing chain than a stock LS1 timing chain?

Comparing the two, the ls2 is substantially thicker.

have you seen the comparo pictures???

they're quite a bit beefier. i haven't seen a tensile strength/stress test or anything, but its definitely quite a bit stronger than the ls1 chain.

ls1 chain stretches a bunch - i replaced mine with a double,,,

I can't see how the chain would stretch as the material would need to yield. I think that GM intentionally put some slack in the stock chain to control bearing loads at the front bearing.

Dont think of the chain stretching as the actual metal links being stretched individually, think of it more like each hinge in each link wearing in to one another . As this happens each link moves ever so slightly further apart. The idea is similar to offset grinding a stock crank for increased stroke. Add up the small seperation between each link and the sum results in a stretched chain. Even so, after 75K miles on my stock ls1 chain, I couldnt really tell a difference in tightness when I put on the new ls2 chain. There was still some slack in it.

The LS2 chain is alot stronger than an LS1/Ls6 chain. In fact if you were to bring a stock LS1/LS6 car into your GM dealer for service work & it needed a new chain they would use the LS2 chain. We have built several 402 LS2 that are making big hp #'s, and that is the only chain we can use (for now).

We keep them in stock, if anyone is in need of one!!
