yeah that will do nothing for our trucks. and honestly, unless their steering racks have some kind of lock for the amount of turns the wheel can go, adding those spacers does nothing cause the rack can only go as far as the teeth that are in it.
they are also talking about rack and pinion steering compared to our draglink setup. adding spacers would make the tire toe out, so when you went to set them back straight, you essencially jsut jsut got rid of the spacers. to change any kind of steering angle or input you would have to change the centerlink, pitman/idler arm mount position, or knuckle connection to the tie rod
