ls2 timing chain i have a ls6 and just put a ms4 cam in it, is it true that a ls2 chain and gears are stronger if so would a timing set for a 06 trailblazer fit, just looked at jegs and they offer 3 diffrent sets for different years what do i need thanks
I have bit my tongue long enough.... What is it about the ls2 timing set that makes them so special? Aren't they double roller? Ya know i've never heard of anyone jumping time or breaking a ls1 setup. Have You? Or anyone else? I mean obviously they wear out and stretch but all setups will do that.
Heck My Vortec 5.7L will roll over this weekend to 239K and it still has the original timing set in it.
Im building a "ls1" (5.3L bored to 5.7l) and i am putting a ls1 set on it. Im a firm believer in not trying to fix stuff that AINT broken.

The ls2 chain is beefier than the ls1 chain. When u get that new timing set if it is a gm part it will be a ls2 chain anyways. Unless u get the junk chains for ls1 at a parts house. There is a very noticable difference in a ls1 chain and ls2

LS2 timing chains are stronger then stock LS1 timing chains. LS1 timing chains are known to stretch over time so its not a bad idea to replace the stock chain with the LS2. For only 42 dollars I feel that it is definitely worth the time as you are already down there doing the work anyway. You can buy aftermarket chains for not that much more money but for someone on a budget looking for a decent chain on a mild build it is a good deal.

GM replaced the LS1 chain with the LS2 it is a stronger unit...and to the poster that asked has anyone ever broke a LS1 chain or known anyone breaking one the answer is a resounding YES...for the $$ you cant beat the LS2 chain.

Are you saying to JUST replace the chain for $42 without replacing the cam/crank timing gears? If you are....i would have to totally disagree with that. The gears are already wore in to the old chain and the NEW chain would start to wear in and tear the hell out of the gears or vice versa.

I just got done pulling apart a RUNNING 5.3L with 255k miles on it and yeah it was stretched but hey i would say 255K is pretty good mileage!
I saw the pics posted above (link) and its obvious the ls2 setup is alot beefier.
Im not putting the ls2 down but i would weigh cost vs. appication BEFORE i just ran out and got a ls2 setup just because everyone says they are "better".
Looking at the pics, if the price is right....I am putting a ls2 setup on my LSX build.
Yes i am running in circles!
Need a little bit more info.... was the engine in a drag car or DD? Did car have nitrous or supercharger? How many miles during the break?

The engines that broke chains were built/modded engines...(a couple of them were high $$ builds) some with single row chains and some with double row chains. All were being used for road racing or autocrossing. I am sure that a lot more people than myself know of them breaking too they just have not read this thread. But breaking timing chains is few and far between problem. But you made a statement that was far from true. Just an FYI for ya...you cannot buy a LS1 chain anymore ...as was posted numerous times already GM superceded it with the LS2 chain...if a $35-$40 priced part is hard on your budget you are in the wrong hobby/sport.
PS There is a big difference between the strain on a truck/SUV engine than a modified LS engine being run hard up and down threw the gears. I see LS engines with well over 200,000+ miles on them all the time I work at a Chevy dealership.
ALL timing chains stretch over time. As a matter of fact ALL chains stretch over time. Bicycle, chain saw, motorcycle....you name it. But how much of a TIME frame are you talking about? Of course they will be stretched with 150k miles on them.

Its not a question of affording $35-50..its common sense...why spend $50 on a DD engine when you can get away with $35 and take the extra $15 to spend on spark plugs.
That is how i have made it this far doing well....by not squandering $$ just because.....But your point is well taken....High end engine and/or trackstar needs the heavy duty equipment.
