Pull the thin membrane off the back of the ribs (grab it with a paper towel), then cut the racks into 3-4 rib sections.
Mix the brown sugar, paprika, chili powder, garlic powder, salt, and pepper and rub it all over the ribs.
Stand the rib sections upright around the slow cooker, meaty side facing out, and drizzle with 1/2 cup barbecue sauce.
Cover and cook on LOW for 7 hours (or HIGH for 4) until the meat is tender and pulling from the bone.
Line a sheet pan with foil, lay the ribs on it meaty side up, and brush with the remaining sauce.
Broil for 3-5 minutes until sticky and lightly charred, watching closely so the sauce doesn't burn.
