Prepare a grill for indirect heat. If using a charcoal grill, build the hot coals on one side only. If using a gas grill, heat one side only to medium-high heat. Place a pan filled with about 1 cup of water next to the coals for additional moisture.
For the ranch rub: Combine all the ingredients in a medium bowl and mix well.
For the ribs: Using a dry towel for grip, peel the membrane (silver skin) off the bone side of the ribs and discard. Generously season both sides of the ribs with the ranch rub.
Place the ribs bone-side down over indirect heat, cover the grill down and cook until the internal temperature of the ribs reaches 140 degrees F, about 1 hour. Wrap the ribs in aluminum foil and continue to cook for another hour.
Take the ribs out of the foil and put back onto the grill, still bone-side down. Spritz with pickle juice, cover the grill and continue to cook until the bones start to pull away from the meat, another hour or so. Check the ribs by flipping a rack over so the bones are facing up. Press your finger on the meat between the bones. If there is some give and the meat starts separating from the bone, they are ready. If not, continue cooking for another 30 to 45 minutes.
Remove the ribs from the grill, cut into 1-bone pieces and pile onto a platter to serve!
(Alternatively, you can bake the ribs in a 300 degrees F oven for 3 to 4 hours.)
