i remember reading a while back about eagle h beam rods and for turbo it's wiser to go with the one what has the bigger bolt that screws the cap together like a 3/8 vs 7/16 head, is there a name or part number for the specific rod? is it the esp? i've been looking at piston + rod combo but wasn't sure if i should specify the rod or are they now all one size? or don't worry about it. thanks in advance.

 

there used to be an option for the 2 sizes. Now I believe that they are ALL the same 3/8ths inch size, so there would not be a separate part number. those 2 sizes were from a few years ago.
