While we had junkyard calipers, they weren’t on the shelf. They had been in the backyard for the past five years exposed to the elements, so it was questionable if they would work. We were also missing some of the necessary installation hardware. Fortunately, Rock Auto stocks loaded calipers with mounting hardware for only $78.79 each, which includes a $10 core fee. Because they are dual-piston, we had to order one right and one left caliper. Also note the Warn hubs that we were able to reuse along with our Ford hub and Jeep stub shaft.
