I ordered one from GMpartsdirect and they send me something that looks like it is off a cavalier. So not only did it take 2 weeks to get it is the wrong thing! Any help will be very appreciated. Thanks!

 

hey my friend,there are two types of lt4 chain,the one that comes with the lt4 its dinky lookin but it can handle alot and the HD-lt4 chain .

 

But shouldn't it match up to the it4 chain? Whats the dif between the lt1 and lt4 chain?

 

Oh I'm sorry, the only item I had to order was the cam sproket.My bad.

 

the lt1 chain is not a performance chain at all i had freinds breaking them with typical upgrades,stock chain cannot handle excessive rpm.the rare lt4 engine came with a stronger chain due to the needed rpm of the lt4,then they came out with the heavy duty chain that is beefier and can handle the hi rpms the lt4 hot cam/kit provides.i wish i had a pic of all three chains so you can see for yourself the differences,i can say this the factory lt1 chain looks similar to the old school ugly chains,the lt4 chain is more like a heavy duty bracelett,the cam gear is solid and the lt4 HD chain is a beefy bracelett and has a solid cam gear as well.what was the part number of the 4 peices you recv'd
chain #
cam gear#
crank gear#
h2o drive#

 

I didn't think you could use just the cam gear with stock other pieces, but I might be wrong.

set

 

hmm, i am not sure about that!

 

That I don't know. I just bought the chain and and cam gear from a member og this board and ordered the crank gear from gmpartsdirec pn 12555886.

 

I'm confused. First you say you ordered the set. Then, only ordered the cam gear? Now you say it was the crank gear.

 

I bought the lt4 chain and cam gear from a member of this board. Then I ordered the crank gear from gmpartsdirect. Thats it.

 

You may have the correct crank gear. I too was a little skeptical when I saw how whimpy the dang thing looked. It came in my complete extreme duty lt4 timing kit. Its on the car now, so no photos, but the piece is whimpy as hell compared to the monsterous cam sprocket!!

 

Yeah, I saw that you posted that. It's all the stuff before that didn't say or said something different. Confusion could have been avoided.

 

This is the LT4 extreme duty set (ignore the holes in the cam sprocket ). Unfortunately, the socket and bar are blocking the view of the crank sprocket a bit:

Thanks. I'll try to get a good pic of what I have on here tomorrow.

 

Here's a pic of the stock (installed) vs the LT4 (not ED, but stock replacement for LT4 engines) chain:

I thought it looked pretty whimpy at first, until I looked a bit closer--there's strength in the design that won't be noticed by most eyes.
