Complete System, we pride ourselves on delivering complete and detail oriented performance brake solutions to our consumers. We do not cut any corners. To give an example of this, we assemble the hubs prior to sending them to you, installing all the bearings and races, packing them with Redline synthetic grease. When we send you your brake system, everything is already installed, all you have to do it bolt it onto the control arms. Fits 1963-82 Chevy Corvette w/Ridetech TruTurn Suspension & Spindles
