Hello, I'm Ron Bobian from Diamond Racing Pistons. This is Mike Panetta from Diamond Racing Pistons. Today we're going to highlight some of our new products. I'm going to start with this big block Chevy line. It's called the Competition Series. We do these in a pretty good variety to fit a bunch of different boris sizes from 400, 500 up to 4, 6, 25. We have them available in a bunch of different compression distances for all the different combinations with the 24 and 26 degree heads. We also do the SR20 for the Brodix head. All of these pistons have a 3D radius dome. They will not require any kind of deburring or radiusing on them. It is a true drop-in style piston. They come with gas ports. It's got an 043 top ring. It comes supplied with tool steel pins. It also has a skirt coating. We also offer the Competition Series in the L. S. Chevy based engine in many configurations. Anywhere from a street style replacement to a full out race type box style short pin power adder type forging. We offer them with a 185 wall, 4130 wrist pin, molly skirt coating. Also, we do the same process we do Full 3D milled pockets for your basic drop-in replacement type part. Thank you for your time.
