Default JP Racing/N Motion Double Roller TOO LONG

I ordered the SDPC ls2 conversion kit for my new engine. The "JP Racing" Double Roller kit did not fit correctly. The chain was so long it was just hanging there. So I returned it.

I ordered an N Motion kit next from Byun Speed. Guess what? It's the same damn set. Same problem. WTF is up with these things?

Check out the pics.

This is the old, stock chain vs this new double.







Here is the old, stock ls6 chain sitting on the front of the this timing set. Perfect fit.



Any ideas? This BS has set me back 2 weeks already. I'm sick of it wasting my time.

Nobody has a clue it seems on this issue. My conclusion is that this timing set and JP racing are just junk.

Twice from 2 different vendors? Both with the correct ls2 part #?

Also, they do not make a chain for the RHS blocks, etc from what I can tell.

That chain has one too many links (count them). I put a rollmaster double on mine, works great.

Wouldn't it be great if you always got what you paid for?

I ended up ordering this from Comp Cams after reading up and calling them.

http://www.compperformancegroupstore...Category_Code=

I found an actual pic of it online verifying the 1x reluctor. We will just have to see on the length. It SHOULD NOT be a JP Racing chain.



I was hoping to find a shop with what I needed in stock so they could compare the length to a stock ls2 chain before shipping, but a 3-bolt, 1 pole, 24x reluctor, double chain is not super common. Only 2005 corvettes and a few other cars had them.

Yea. This shouldn't be a complicated deal imo. I'd have no concerns just running a stock ls2 chain in most cases. This setup will make 900rwhp+. I want something pretty strong.

You are absolutely right!
Hope someone is reading this. C5R chains are strong enough, in my opinion.

Well, I haven't install it yet, but it appears Comp Cams knows what size timing chain an ls1/2/6 motor uses. Not sure WTF this JP Performance out of Australia is up to. Both timing sets use a Rolon chain. The JP chain just had 2 extra links in it even though it is specified to work on a 2005 corvette just like this one.

It's not the quality that was an issue. They just keep putting the wrong chain in the box.

New comp cams timing set does fit. I put it on last night.

I just received my kit from Texas Speed and have the exact same problem. Man this sucks. Another 3-4 days before I can get my engine back together.

When you call them make sure to let them know I wasn't just some moron that couldn't install a timing chain, and I would like my refund already after 2 weeks. They lost a customer on this one.

The 2nd jp performance chain I bought from Colorado Speed. They handled it much better.

You can get the C5R chain in billet/ billet adjustable timing sets from SD! Just talk to Jesse.

Any style. No sensor hub, 1x, and 4x.

Daaaamn!
That **** is long!
Ls1x2, did they actually think you were full of it after those pics?
Not good! They need to do a quality check of those chains before a bunch of guys damage their motors.

I'm not 100% sure what they thought. They didn't show any interest in pics. They wanted to send me another one out and have me pay for it, or they would wait until they received this one before sending another out.

Nobody in their right mind would put the cover on after installing that chain. It is beyond obvious that it's not going to work.

I am sorry for the delay. You got one of two of the only N-Motion/JPPerformance chain sets that we shipped that had too many links. We have counted every other chain set we had on the shelf, and they were all correct.

Feel free to contact me if you have any questions about the exchange process or refund on the set if you decided to go that route. I am the sales manager here and would be happy to look into your order and ensure the process to get your chain set replaced is or was done quickly.

Thanks!
