    Always good to change wearing parts when you have the chance. If you're in there why do only half the job.

    so you're saying the stock gears for the timing chain only support a single roller chain rather then a double and if I get a double roller chain that it won't actually be used properly?

    sorry kind of a newb and haven't seen under the timing cover of our engines yet...

    the double roller has 2 chains, therefore it needs 2 gears on each shaft. they arent a picnic though. ive read that you have to do a little minor machining to some of them to get them to fit. i just got the ls2 timing chain for mine. i spin up to 6800 before i shift

    Stick with the single chain LS2. I spin over 6800 as well and have no problems. Plus, it can be a bitch to get the timing cover to fit with the double roller. I don't think it's worth the headache. If the car has over 60,000 miles on it, go ahead and change out the gears while your at it.

    What are you doing to the car and how many miles are on it? It's pretty much a must if your using dual valve springs.

    No. On your average car with a timing chain, it never needs to be serviced unless it develops excessive slack or it breaks, both of which are pretty uncommon.

    However, our engines are high performance and are subject to high RPM's, and therefore more likely to stretch or break, so changing the timing chain while you are in there is good idea.

    +1. Unless your doing some major mods to the valvetrain, I wouldn't worry about changing it.

    I would always change the gears with the chain. If you have ever had a dirt bike or chain driven atv you would know why
