It retains your factory front struts while correcting suspension geometry, clears up to 37\" tires with the right wheel backspacing, and is made in the USA. The FOX 2.0 Adventure Series rear shocks step up from the base Nitro Series with an IFP monotube design and race-developed valving. This is a more involved install than the 4\" kit — Zone lists a reciprocating saw among the recommended tools, alongside ball joint and tie rod separators. Confirm these application conditions before ordering: it doesn't fit diesel or Tremor trucks or anything with CCD, it requires frame bracket modification, and 2-piece-rear-driveshaft trucks need the
