I'm getting the idea that most people are not using a double roller chain on a LS2 or L92 block. What are you using, just the GM chain, or is there something better. What would be best for endurance racing with .600 lift and 918 springs. Got Part Numbers??

I'm using the OEM LS2 chain and original timing chain dampener. I was shifting at 7000-7200 rpms at the track. However that is drag racing and not road racing.

If it's OEM, it should last for 100K right? Are the sprockets heat treated, or soft steel.?
I found a part number for a GM HD chain 12586482. What are the numbers for the sprockets.

100K on a street car should be no problem. I can't say the same for road racing. I honestly don't know about the sprockets. I use the OEM LS2 sprocket because I have the LS2 block which has the cam sensor in the front cover. Otherwise the LS2 chain works fine with the LS1 sprocket.

We use the GM LS2 chain and sprockets on the Nascar spec engine. No problems. Sorry I don't have the part numbers with me, I'm at home right now.

With 20k on the clock my chain has stretched quite a bit. I'm going with the Rollmaster Red Label set.

i got the comp timing chain and both gears double roller timing chain, it will also work with the cam sensor on the LS2 , its accually especially made for LS2 engine with the cam sensor on the timing cover , plus there is no problem with it hitting the oil pump , the only thing is its like $200 but im sure its worth ever bit ..
The GM single for the LS2 will work well in a road race engine, and the stock gears live well also.

I have always run a double roller, but it's a new ball game with LS engines.
The Comp 918 springs are not that heavy, and with .600 lift it sounds like you guys are confident that the LS2 chain will work for 30 minute road racing and street, Right???

I paid the extra money for the Katech chain along with Comp Cams Hex-a-just LS2 (heat treated) gear set. Mostly for my peace of mind!

I would be very interested in finding out if this set really has a Torrington bearing. Comp says it does, others have stated it doesn't. If it does, I will order it in a heartbeat.

That comp set is a single roller. Only doubles out there is the JP, N Motion, and Cloyes that I've seen.

It doesn't.
I just finished installing one about an hour ago.
Its definately a nice piece though. I really like the hex adjustment.

Only for information, N Motion and JP are one in the same, N Motion is private labeled for SDPC by JP. Also, JP bought out Rollmaster so they "may" become identical parts going forward. Not sure what their plans are at the moment.

Thanks for the input. Curious, did you notice much cam retainer plate wear? That's one major advantage of the Torrington but in another thread someone stated they found the most cam retainer plate wear on the cam side of the plate, which the Torrington won't help with.

WHAT the !@#$ The Comp chain is a single (?) roller with no Torrington bearing, for over
$200 !! I'm sending it back, I thought I was getting a double. For all of the downshifting and endurance of road racing, I am going with a double so it will last forever.

That is what I have. I bought the Katech chain to go with it! There is nothing stonger! You don't get much wear behind the cam gear. Most of the wear is on cam side.
Most of the time you get what you pay for!

I have the Katech chain right now but nothing to run it on because I have been looking for one with a Torrington bearing. Do you have more information on the wear of the cam plate?

The only LS2 single chain timing set with the torrington brg that I know of is the N-Motion from sdpc.
As far as rhe wear on the plate, my original LS1 had vitually no wear on the plate after 100,000 miles. I just put a new one in my 427 because I wanted no stone left unturned. I really don't think that the plate wear is something the average LSX/owner has to worry about. If it was gm would have included the torrinton brg. on the LSX high performance engines.

I have a 2006 LQ4 with less than 5K that I'm doing now, on inspection for the cam change this motor had some cam plate wear that was obvious. This motor has hex head bolts that hold the plate. Some earlyer models have bolts. If you check the Vinci web site you can read more about it there. As for chain sets I'm using a single Rollmaster that does have a torrington bearing with billit gears. It will serve my purpose and has a good price.

FYI
I broke my Stock 2005 GTO LS2 chain last Wed going down the highway boosting it in 3rd gear
we made 735RWH last fall, then after about 2000 miles about 130 street passes and 30 or so Drag Strip runs, we dynoed it with the full 3.5 single exhaust and it made 749RWH, this was earlier in the day before the chain broke and bent my valves.
35K on the car.

I know someone else that broke their stock LS2 chain a couple months ago as well, bye bye valves and pistons, had under 500 whp as well. Buy a good chain!

I bought the SDPC chain & gear set (HD single). Its a nice piece & what they use on their built engines. LOL
