This massive 8 piston caliper was originally developed as a "Quick Change" caliper for the 99-04 F250/350 trucks.. This caliper will replace the factory caliper, fit over the factory rotor and fit in all the factory wheels! Yes an 8 piston caliper in a 16" wheel!! Of course we could not stop there, other applications include C5/C6 Corvette, 05 & up Mustang and the front brakes for Worlds FASTEST production car, the Ultimate Aero TT! Just like all of SSBC's calipers the V8 8 piston caliper is built to out perform and out last the competition. Made from billet aluminum this massive 8 piston caliper includes stainless steel pistons, stainless steel pad guides, internal oil seals, dust seals and a smooth exterior design..
