Harrop Trutrack Or Circle D Hi Stall Convertor?

I spoke to an ARB rep @ a 4x4 show 6months ago. He said they had already done one of their ARB air locker diffs for a ford drag racer.

I asked if it was feasable for the air locker to be activated using boost pressure, the answer is no. Is recommended for stationary engagement, but low speed, no load is ok.

Still, an air locker should stop the asre end shaking around and stepping out over bumps from the lights, on the street.

I read a comprehensive review of the Trutrack, vs Detroit locker, vs ARB air locker for in an American 4x4 publication. The trutrack still allows differing left and right wheel speeds and is not considered the optimal solution for off road, but doesnt require input from the driver.
