I have ARB air lockers front and back in my Jeep. They are worth there weight in gold on the trail. I only have 31" tires and about 3" of lift, but can take most obstacles with ease because of the lockers. I get lots of questions about the lockers from other Jeepers on the trail after they see them in action. I have had the ARBs installed for over nine years with zero problems. I highly recommend them.

Do you need them for your truck? Depends on what your going to do with it...
