Yeah I'm glad he chimed in, I cab probably learn a few things from him. Well as far as the air locker goes I will have more to worry about breaking, but I get the advantage of turning it on and off. Altho I've never owed one, but what I've read is it gives an equal 50/50 ratio to each wheel unlike a tru trac or other lsd's. So in other words it 100% once it's locked and open diff when unlocked.
Becuase the air locker wont be under constant stress, it will more then likely but LESS wear on drivetrain, then a daily driven and tracked vehicle with a welded diff.
A welded diff eliminates the ability for a difference in wheel speed in all conditions. An air locker, when locked does EXACTLY the same thing. A spool would be the better version of a welded diff (less chance of failure). But are not available for our 8.25"/8.4" rear ends.
Lunchbox lockers/racheting lockers work fine for wheeling but can fail and be unpredictable when they lock/unlock. Nothing you want in drifting.
Clutch type lsds can fail over time, and need to be set up properly for the motorsport you are doing. Drifting in particular, a 2way lsd (lockin under acceleration and deceleration) set up for drifting would be set up so tight, that it would be terrible for daily driving and fail prematurely.
But if you have the money (and they actually make em) a 2way is the way to go for drifting. :top:
