Based on the oem design, they are beefier everywhere. We have seen every attempt to make a stronger oem style rod ever done, and the Super Rod is the best. Perfectly sized big end bores and bronze bushed pin holes. Brightly polished to help prevent oil cling. The strength comes from their bulk. At 372 grams, they are 70 grams heavier than Carrillos, but at a very attractive price.
Now with Super Rods, there is no reason for modified street bikes to chance using stock rods any longer.
