Default rollmaster timing chain

Amazon.com: Rollmaster CS1135 Billet Roller Timing (Set with Torr. Brg, GM LS1), 1 Pack : Automotive Amazon.com: Rollmaster CS1135 Billet Roller Timing (Set with Torr. Brg, GM LS1), 1 Pack : Automotive

This is legit right? Spoke to Texas speed today they recommended this part number it's a bit cheaper than what they sell it for.

That’s the unit that I use 95% of the time on builds. Now…it it a genuine RollMaster being sold on Amazon, or a cheap copy? I’d pay a little more from a known vendor for the peace of mind personally. Lots of knock-offs and fakes out there.

I would call the Rollmaster customer service # and confirm whether or not they offshore their production.....

I've used Rollmaster before. I remember the first time I ever bought one. It was recommended to me by a knowledgeable performance shop. I'd never heard of them. I've never had a problem with them, either. Would use them again. Wonder who makes the C5R chain?...

I used a Rollmaster single roller chain in my iron LS3, they come with Iwis chains, I don't have a tensioner.




Summit has them so you can bet its gonna be an original one not the Chinesium stuff and cheaper than Amazon.

I buy mine either from WS5Store or Summit. They all have made in Australia on the box. The op’s first post with Amazon link has the unit made in China, hence my original thought of copy’s or fakes out there. buyer beware.

Yup. You can't be too careful. Its tough, because made in USA parts can, and do fail, occasionally. Throw a bunch of half-assed manufactured counterfeit China junk into the recipe, and the odds for a recipe for disaster increase considerably. Sadly, if they're a good looking fake, the manufacturer ends up getting blamed and flamed for something they didn't even make....

As far as the original post goes, at least the Amazon page that is linked does say the parts come from China.
At least there is SOME truth in advertising....

While everything said above about buyer beware is true, I wouldn’t think that the country label on Amazon is anything more than some copy paste action going on that mislabeled it when the page was created.

I went to the actual Amazon page where the timing set is sold from. It's in Amazon's description of the parts that says they are of Chinese origin. Not the label.

we are talking about the same thing. I should have worded it differently.
I was going to reiterate not to trust the description, as someone was either ignorant or lazy in coding the page, but.. lol, kinda proves the point. If you can’t get the website correct, how can one be sure the part is correct too?

I have bought a rollmaster timing set from them, and it was a genuine one. I’d say if you aren’t familiar enough with them though, you might not see the differences.
At the time I got my last one they were the only ones anywhere that had linebore sets available.
So not much choice if I didn’t want to wait an unknown time. (During Covid when there was 30+ shipping containers parked off Long Beach)
I did feel more confident that a -5 linebore set would be genuine and not counterfeit, as I’ve never seen a China linebore timing set.

I’m interested in knowing if your set comes with an instruction sheet concerning chamfering the cam retainer plate. It seems that some sets do, and some sets do not. The chamfering is for the Torrington bearing. Let us know please, if you don’t mind.

Mine did. Took about a minute to clean up the edge on a mahle cam plate. I don’t think there was any interference before, but taking the lip off didn’t hurt anything
