That's a very good kit, it doesn't get any better than Revolution Gear & Axle.... it's definitely worthy of 35" tires.



So far as the ring & pinion gears go, the only thing that has to be done is to set the backlash which is not difficult, at least not nearly as difficult as setting the R&P gears up from scratch. Setting the backlash only involves shimming the ARB carrier left or right until the right amount of backlash between the ring & pinion gears is achieved. Enough preload also has to be included to make the ARB tight enough to require a couple blows from a mallet to seat it into the housing.



However, there's a lot more to getting the rest of an ARB air locker installed properly than just getting the backlash set. That is why ARB strongly urges it be installed by someone who is experienced at installing ARB air lockers. Not just lockers, specifically the ARB Air Locker which isn't an easy install. For that reason, I wouldn't consider this kit really installable by Joe-average shadetree mechanic even if setting the backlash would be an easy job for him.
