Shot peening polished rod sides

[mike7570]

The rods that came out of my tunnel port were from the Mickey Thompson Bonneville car with the H/M engine. The beams were finished in a polished surface not shot peened.
They were heavy 956 grams and I eventually switch them out for aftermarket H beams.

Two of the comments above speak of shot-peening as 'stress-relieving'. Actually the reverse is true. Proper shot peening, as Barry said, compacts the surface of the rod. Think of it as the equivalent of putting a sleeve of harder and stronger material over the surface of the rod. This process actually induces stress in the surface, but in a good way. Of the total of five years I spent at T&C Livonia, the two after I graduated were spent as a metallurgical process engineer in Quality Control.

The aftermarket rods available now are far superior to anything we could produce by re-working production pieces. And they're NEW, not something that's had many years to accumulate difficulties.

Re-working race/use rods, perhaps. I have less than 400 miles on a set of NOS rods that were given the treatment.
