is the stock one good enough, or would i better installing an aftermarket one?? my shop would start my cam installation tomorrow, and since they would be working on the engine i thought of getting an aftermaket one, i remember Katec is making one for the c5-r corvette, i wonder if that one would fit on our engines??, or maybe the new era double roller timing chain?? or any other recommendation??

I've had a hard time finding a good double roller LS2 timing chain. Only single rollers seem to be available. I'm not sure why.

 

[BlueGoat06]

what's the difference between the double and single roller ???

new era seems to have a double roller for the ls2

Kewl. Good news about the double roller timing chain.

The difference between the double and single roller is kind of explained by looking at a bicycle chain. A double roller chain has two chains that are connected and the sprockets are also doubled up. Whereas a single roller just has a wider single chain.

The Katech timing chain is awesome thats what I am running. Yes their timing chain is used in the c5r race motor with no failures so I trust it.

I too went with the Katech...

 

[BlueGoat06]

can i use the katech in the ls2 engine??

 

[BlueGoat06]

or better, do i need a katech timing chain???, do i need a new timing chain at all???

If you are low mileage you can definatly get away with not changing it as from what I understand the LS2 chain is better than the Ls1.

i have 15k miles.

changing the chain, requires removing the oil pump. My point is it will add additional cost to your cam change. with 15,000 miles you should be OK.

I would just evaluate your driving habits, or how you anticipate you will be driving once the new cam is installed. If you are an occaisional romper I wouldn't bother with the swap. On the other hand if you flog the car consistently changing the chain now would be relatively cheap insurance.

I replaced my 44,000 LS1 chain with a LS2 timing set. I have had no problems and I beat on the car pretty good. It is smart to replace the chain and sprocket at the same time. They have certain wear patterns. Problems could arise if only one piece is replaced. I would keep the stock LS2 chain.

I actually got my double roller for my 403 LS2 from Mike at New Era Performance which is a sponsor on here he gave me a great deal.

I've been using the Comp Cams single roller timing set on the LS2 blocks. It features a pre-stretched Reynolds chain. Strong as a SOB...

Rollmaster is coming out with their own LS2 double roller timing sets very soon. I have them coming in on my next stocking order. Billet steel sprockets, nitrided, Torrington roller bearing and nine adjustments. They will use the same reliable German JWIS chain and not the weaker Roll-on chain.

Let y'all know as soon as they clear customs.
