About this part
Component Box, fitment-checked
A JK-generation component box covering a 3.5-4.5 in. band, supplied against kit JK42RLSBO. Coverage is the 2007-2017 Wrangler including the 70th and 75th Anniversary editions, plus the 2018 Wrangler JK.
This is the older JK platform rather than the JL that succeeded it, so check which Wrangler you have before ordering: the two share almost no suspension part numbers. The box covers a 3.5-4.5 in. lift band and is supplied for kit JK42RLSBO. Coverage runs the 2007-2017 Wrangler across Rubicon and the 70th and 75th Anniversary editions, and the 2018 Wrangler JK in Sport, Sahara and Rubicon. 43.6 lb boxed. As a component box it belongs to a larger kit rather than standing alone.
