As cylinder pressures, springs pressure and rpm increase, the stress on your factory pushrods increases far beyond the level of stress your factory pushrods were designed for. If you are above 500hp with your ISB you need to upgrade to the heavy duty pushrods. If you are over 750hp, the stresses in your engine dictate that you go with our extreme duty pushrods.


Push Rod Specs: 3/8" x .120 Wall.

Don't settle for light duty stock replacements that are only .083 wall thickness.

Great for street & strip application.
