Wouldn't surprise me ... Gotta maximize profit margin while maintaining market point.

Both JP and Rollmaster are made by the same company, My understanding is that JP are a more of a budget brand, like the rollmaster blue/red series are.

Yes they are now, but weren't when JP were having the failures. From memory it was rolon chain they were using then.

My Rollmaster double row set in my current L67 is IWIS Chain, & from memory it was stamped. It also had the one piece crank sprocket with the adjustable position for timing cam degreeing. Then they started that shit two piece crap which most find has to be heated up to get on. Where as the one piece crank sprocket had a fit similiar to the stock slide on crank sprocket.

Both of mine were 2 piece and fitted fine. But if quality control isn't the best they could vary from batch to batch.



btw, I sent a message to Precision engine parts asking if their gold series ones come with Iwis or Rolon. They are pretty helpful so I should get an idea if its wide spread or not.

Great spotting guys

Ive sent a message to the seller first asking what's going on with the Rollon chain, it even says it on the box that it comes with "Exclusive" IWIS Pro chain. I think rollmaster do whatever lol, unfortunately who else do you buy these kits from, they have the market?

[vlad01]

As far as I know, no one else makes a kit so we are all stuck with what they make. Real shame for the quality to be so hit and miss for the world wide good reputation they have.

supplier is asking Rollermaster what the go is as they just onshipped from them apparently.

If im outta luck ill use the new sprockets with the old chain, but pretty sloppy production just in my experience so far. Even if it's now ment to come with the cheaper rollon chain it still says iwis on the box.

That, I would not do!

The old chain is the other kit iwis chain. It's new, well 2000km

Any updates on this? I am trying to sus it out with one supplier and a v6 builder on what their experience is with them recently but haven't heard back yet.

I need to get a timing set for my next engine and I certainly do not want cheap parts being the weak link in what will be an expensive build. And as it will be a very big cam with lots of valve train load I can't afford any problems.

Not looking good
