Right Stuff builds front, rear and complete disc brake conversion kits for popular models. Upgrading to more modern disc brakes is a great idea for safety and performance reasons. Many disc brake conversion kits are available for front as well as the rear. Right Stuff rear disc brake conversions are popular on 10 and 12 bolt Chevy rear ends as well as 9 inch Ford rear axles. Right Stuff also bends brake lines to factory specifications in steel and stainless steel for many cars and trucks.
