ARB AirLockers F/R 71 K5

[AsianBlazer]

Hello,

I'm considering ARB Air lockers for my front diff, a Dana 44, and my rear diff, a corporate 12 bolt. I believe they are both bone stock internally. Is there a simple way to determine what gearing they have to pick the correct ARB set up to order?

If the 44 still has the small ratio tag bolted to the front cover it will tell you. If not you can pull either cover and look at the ring gear. It should have the pinion and ring gear teeth numbers etched or stamped on it. For example 3:73 should read 41-11, I’ve seen them stamped the other way too; 11-41 either way if you do the math from there you’ll know what you’ve got.
