Hey guys...installing my LT4 Extreme duty timing chain. I was curious. Is there supposed to be play in the chain. I know the stock one didn't have any. But this one appears to have quite a bit.

thanks...

 

i believe they are suppose to be pretty loose. I have a extreme duty, but i never tried the stock crank gear. Thunder racing sells an oversided gear to take up the slack and thats what i bought. When i put that on it was nice and tight. I would recommend getting one.

 

Anyway, the more I look at it...its like a bike chain and any other type of roller. I know they are supposed to have play. Just wondering if its the same for this application.

 

Mine had some play....but not too bad.

I was concerned about the slop in mine so I called the guys at Lingenfelter and was told that it wasn't an issue. Still would have felt better if it was tighter.

Anyone else. I wanna close this boy up. I would say it moves like 1/8th inch.

 

With the car running, the chain will have slack on one side and be tight on the other. That's just how it works, so yes, there should be a small amount of slack in the chain.

 

I also got the oversized crank sprocket from TR. Slack

 

I did not notice much slack when I installed the LT1/LT4 ED timing set. It certainly was tighter than the loose and whimpy oem chain that I removed.
