As the title suggests, what are people's thoughts about replacing just the chain and not the gears for the timing set? I'm in the process of an engine rebuild after a spun bearing on my car and I've been going through the regular wear parts to see what to replace while I'm there. With 126,000 miles on the engine the timing chain is a little on the slack side from the look of it, so I figured I'd replace it. However, a full timing set from Mopar is $500+, which is just crazy to me. I can get a chain for around $75 without the gears, but I know the sprockets will wear a bit funny with a stretched chain, so I'm hesitant to replace one without the other, but $500+ for a stock factory timing set is just beyond dumb to me.
