Spec anchored to the OEM owner's manual; the capacity, when it carries the verified badge, is cross-checked against an independent source. Never changed by what an affiliate link pays us. Your owner's manual is always the final word — and if your axle has a locker or an option package, double-check the capacity for your exact build.
