A stock non-T/A factory box is 3.5 turns lock-to-lock; the T/A ps box is ~2-2/3 (~2.66) turns lock-to-lock, and that is caused by the internal stops within the T/A box (cannot be removed, per info from FF... told to me by FF).

So, for the Borgenson ps box, regardless of which pitman/idler arms, what is the actual turns lock-to-lock? In other words, the Borgenson ps box will NOT be having internal stops AS the T/A box has that makes it different from the non-T/A factory ps box.

In fact, the Borgenson ps box -- by adding the longer pitman/idler arms -- should allow a smaller (tighter) turning radius with the longer arms, BUT, the lock-to-lock will remain the same. The only way it could be less, is IF the extended arms causes the tires to more quickly hit the inside frame rails, thereby, limiting the turning radius (and that can happen the same way the factory boxes already allow).
