If you look at the broken timing chain poll, the amount of stock chains has gone up to about 50%. Just something I noticed in the past couple of days. I myself am running a rollmaster double chain set-up.

 

I'd have to ditto that.

 

One thing to keep in mind with that poll also is, think of how many cars are running the stock setup vs. cars running ANY aftermarket chain. There is ABSOLUTELY going to be more failures shown in the poll for stock chains. Keep that in mind when you're using words like "better" pertaining to aftermarket parts. Not stock doesn't always mean better, it just means it's different.

If you've got 10,000 cars on the road with stock chains, and 1000 cars on the road with rollmasters.. 20 broken stock chains, and 3 broken rollmasters, according to your math, what part has the better service history? (the numbers are just pulled out of thin air to make the point.)

 

OH LORD I hope this does not happen to me

 

I just got this guy, any complaints?

 

Just got what? I was looking into the Rollmaster double with the IWIS chain, but there seems to be a lot that have broke. I found this problem everywhere, Mustang guys, GN guys, etc. I decided to look elsewhere.

 

i have used rollmasters for years zero chain failures,race engines/street engines turning serious rpm/spring pressures way above std should have chains replaced periodically they all have a life limit.....think about that....front cover removal,chain replace(chain cost $30.)cheap insurance i reckon........
cheers dave...

 

oy, i feel like a douche. this guy: http://www.sdparts.com/product/SD3SR...ollerIwis.aspx
Single Roller, Iwis timing chain from SDParts

 

That is the one I went with.

Ahhh, I believe that is new to SDPC. Not sure how it differs from the Katech chain, which is also JWIS. IWIS Ketten makes several chains in this pitch of various quality.

 

Wow 5 years and back from the dead!!

 

It's a new chain, and a great chain at that. You found a thread with issues from 2003 No worries present day.

 

2003.... I did not even notice.

Bill

 

just using the search function.

Thanks scogggin. cant wait to get my parts. should arrive tomorrow. yay

 

If you bought their new IWIS chain, how about snapping a few close-up photo's prior to installing it.

 

definitely. it should be here tomorrow. Pics coming soon.

 

Sorry for the crap pics, i'll take some tomorrow in the day light:

Stock timing chain:


IWIS Chain:

 

Its not the same as the Katech chain. However, note the new chain has one piece rollers and the stock chain doesn't (there is a split in the roller).
