Meet the final solution for the ill-fated S-Caliper piston. You’re looking at the new DuroAno® S-Caliper pistons with metallurgy technology borrowed from every amazing caliper since the 917 caliper.

The thought came to us when we kept seeing S-Caliper pistons flake and fail due to dis-similar metal fusion and original “plated” pistons. The question; why dis-similar metal when we could use similar metal? 930 calipers have aluminum pistons. 951 calipers have aluminum pistons. 908 calipers have aluminum pistons... why not S-Calipers?

The coating process was a key component. As technology progressed, so did the coating process. These new aluminum pistons are harder and more durable than their original or stainless counterparts. Our special DuroAno® Coating makes them the perfect piston for the S-Caliper.

They are feather weight was well. These weigh 1/2 of what a stock S-Caliper piston weighs.

Put an end to S-Caliper woes. These pistons will right the original wrong and last forever.

OMG, these are awesome Eric! I have a set of S-Calipers on the shelf that will needs these come rebuild time. Still a number months (or years?) away at this point, but this is great news. THANK YOU. I'd better not wait years, huh?

Hacksaw, file, sandpaper and some silver paint and I could make them cheaper.

So what exactly is DuroAno? Looks like hard anodize to me?
