So my truck is a 01 suburban 1500 4x4.i run some 24s with a 305 tire.my question is has anyone run a dingo pulley they are suppose to be a smaller diameter an I was hoping would speed up the pump to help turning in parking lots an driveways..plus they look good😁.the 24s make turning very slow.all the front end has been rebuilt even the steering shaft,pump,and plastic vearing so I no it's not mechanical.i no the truck wasn't built for the 24s but looks good.or has anyone done an oem pump upgrade?
