Questions & Answers

Is it also a good idea to replace the gears? 175k in 3ls1. I was replacing the oil pump, so I figured I'd replace a few other things while I was at it. thanks?

Yes, the gears should also be replaced. While I was at it, I'd also install a water pump.

Is this a link from the LS2 chain?

It was suggested to me that it would work with both ls1 and ls2.

Is this chain pre-stretched to break in length in order to prevent it from stretching and becoming tangled?

Sir, I'm not sure; all I know is that it's the same oem chain that came with the engine when it was assembled at the dealer.

Genuine General Motors components

5/5

OEM packaging for a genuine GM part. On an LM7 5, I installed one. 3 on an LQ4 and one on an LQ4 6. They're a direct replacement for the stock gears, but they're noticeably thicker.

It did exactly what it said it would do

5/5

My LS1 was full of slop. After doing some research, it appears that they all do. The vehicle is in good working order.

DOESN'T HAVE ANY SLACK AT ALL

3/5

I bought it hoping it would be tighter, but it has an inch of deflection slack, which makes it worse than the chain I was replacing. I bit the bullet and went with a double roller summit timing set because I couldn't even degree my cam in with this ls2 because of the slack.

During my DOD delete on my 2009 Impala ss, I used this to replace the stock chain. It's fine. (There's also a ls2 tensioner on it. ) cam gear for ls2.
