Some of the after market cases have a steel liner that slips inside the case and surrounds the planetary. Why some must have one to certify and some don't I haven't a clue....

David, I've used an ATI case and it's a very nice piece. Only problem was that it did't come with any instructions on where to drill for a pro tree brake. I called ATI and they said it was just like a stock case. Unfortunately, while in theory it is, the rear of the case has none of the familiar landmarks, like the horseshoe shaped cutout etc. I didn't have to stare at it for long to figure it out, but some specific instructions would have been nice....

Thank you,John.

In the DEDENBEAR the liner is in there so you dont have to run a flywheel OR the trans SHIELDS If anuthing blows up youve got the liner !!! And you dont have to mess with the DAM shields!!! Hate the shields!!! David,

You guy that have used the ATI case have you had any problems with it ? I've heard a few problems before and wanted to know if this was in the past or not ?

I lean this way because Top Dragster pays to win with these cases $200 to win and $100 to runnerup and its a decent amount of price difference to start with. But if its going to be a problem case I'll just buy the other.

I have ran a ATI case for 3 seasons now and have had no problems.
I have a 3000 lb class3 muddrag jeep with over 1300 hp.

No problems at all. I heard that there were some dimensional issues when using one of the Ford pattern bells, but nothing else. The specs with the Chevy bell were on the money. What have you heard?

Heard of several problems with the ati all different from different tranny guys

I pulled the trigger on a new Reid Case today

All in and a done deal ! Very Nice Cases !
