All 2011 Drag Paks come from the factory with a Strange Nine Inch rear axle assembly Mopar P/N P5155850. No Drag Paks came from the factory with an 8 3/4. 2009 Drag Paks had an independent rear suspension cradle with no diff and 2010s had a trailer axle for transportation purposes only. Several racers equipped their 2009 and 2010 Drag Paks with 8 3/4 or Strange/Dana 60 rear axle assemblies but the factory never installed any rear diff in a Drag Pak Challenger until 2011.
