I have recently seen where Manley is now offering a MUCH better chain set up for our Gen3 Hemi's but it involves some spacers for the timing chain cover and I HIGHLY doubt ANY dealership will approve installing one....other than that....I don't know of any "better" chain package that is available to us right now.I inquired if I could pay the difference and get either a dual roller or aftermarket performance of some king instead of the weak looking replacement chain, Chrysler approved of course. Have not heard back yet if I'll be able to.
The information I have shows the old part numbers are the same for the timing chain, the chain guide and the chain tensioner between the 5.7 with and without MDS.First I've heard of this. (With mine in hibernation over the winter, I spent little time on the forum.)
I'm curious why the timing chain would be different on the AT vs. manual version of the 5.7. I wouldn't question different cams. But, a different timing chain? Granted, I'm a noob when it comes to this stuff!
Thanks. I should have guessed it would be related to MDS.... The general conclusion drawn by many (yet unproven through Dodge documentation) is that the MDS system somehow causes an unbalance in the cam which stresses the chain and guide, ultimately resulting in the failure....
