Just bought a brand new JKU Rubicon, was disappointed to learn that the lockers (Especially the rear) will not engage in 4 High or over 10 mph. When driving in deep snow having the locker engaged is a huge plus, but being in low range often isn't ideal. Anybody know of a way to override this?

 

Do a search for the "e-locker bypass switch mod"

 

Just had mine on a pretty treacherous trail with slick mud and did not use the lockers. The Rubi performed like a champ with the brake lock diffs doing their thing. This technology has been in use on Freightliner (a Chrysler product) trucks for years. As a truck driver I've been familiar with it on snow and ice. On the Jeep, in 4wd, it is amazing. I wouldn't go through the expense of this unnecessary mod, personally.
