Cummins Push Rods
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 6bt 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.
