Description
Smith Brothers pushrods are built of heavy wall 4130 Chromoly steel and are recommended for those that will be pushing close to 40psi of boost and above. Factory pushrods can deflect or bend under higher boost. These are the SAME pushrods that we have done over 1000hp to the wheels with on the dyno!
It is also recommended to upgrade the valve springs as well when upgrading pushrods.
