I really wanted to do the timing chain also, I know it will be a lot more work but I just can't have my truck down for any more than a day, I plan to take the cover off to reseal it, it leaks anyways, I'm gonna look at the chain and see how bad it really is, then I'll just have to open it all back up this summer to do the chain and gears, I don't have the extra 70 or so bucks to do it right now

The double roller is less prone to stretching. Once you see the stock unit, and how bad it is, you will have a much better idea of why your engine is down on power. The double roller fellers are a bit more accurate, and will last quite a bit longer before being stretched to the point your stock unit is. It's a cheap upgrade, I can't see any reason NOT to do it.

I just got the water pump and double roller timing chain I ordered from rock auto. The water pump and timing chain are good quality replacement parts and worth buying. I have never seen the stock timing chain on a dodge engine, but I have on other engines, and there total junk. So do your self a favor and get the double roller timing chain, its worth it.
