that rod is a LSPV i think. load sensing proportioning valve...when there is a lot of weight in the back of the truck the rear of it starts to sag...as the back goes down from the added weight it pushes that rod downward which applies more fluid to the rear drums to aid in better stopping with the additional weight. you can take if off, its not needed anymore. with a hole in your bed floor the hauling of rock days are over.
