Saenz rods are polished and shot-peened before final dimensional finishing of the overall thickness and bore sizing. Polishing relieves stresses incurred on the material from the machining process and shot-peening creates an external hardened layer that enhances the rods overall performance. These processes also increase the rods useful life and can be used as an indicator of excessive stresses on the rods after being used.
We recommend these rods for use up to 1000+hp forced induction.
