Hello There:

I asked this question a while back about the Ross Spiral Lock type clips since a friend (machinist) wanted to know why I did not use them in my engine build.

The answer I got pertained to the way the channel on the piston itself is engineered/made. Looking closely at the Mahle or KS pistons you will notice that the channel the clips sit in are rounded, so the Ross Spiral Lock type which is squared-edge will not work for our application.

Also, as some knowledgeable engine builders here have pointed out, if Porsche race engines have used these circlips in their respective Race Cars for years winning at places such as Le Mans, why would I question that experience.

If you search my posts, you should find some answers to your question.

Hope this helps.
