This is the best way to convert your non-disc brake truck to modern disc brake stopping power. BROTHERS "Deluxe" 6 lug kit includes: caliper brackets, remanufactured calipers, caliper bolts, spacers, brake pads, hoses, all attaching hardware, new custom 6 lug rotors, and detailed instructions. This rotor mounts directly over your existing hub once you press the original studs out, therefore it does not come with new bearings and seals. BROTHERS strongly recommends upgrading to the new style tapered rolling bearing conversion (# TRB4759). The kit will work with 16 artillery style wheels, however will not work with stock 15-inch drum brake wheels. This kit utilizes the stock 6 x 5.5 bolt pattern. This item is Oversized.
