V8 Roadsters Ford 8.8 upgrade kits include a Ford 8.8 mount designed to eliminate twist and flex without relying on the subframe brace mounting points – which were not designed to support these components. This also means you can retain the factory bracing. The carrier is offered in both steel and aluminum and has a wide variety of ratios and positive traction differentials. The 8.8 is bulkier and heavier than the Getrag but has enough clearance for a 2.75″ exhaust system. Recommended for the drag racing applications or goals of 700whp.
