ATI now offers 8" & 9" Bolt-Together versions of our popular Treemaster® Converters for TF 904 and 727 Transmissions. For racers who frequently send out their converters for stall changes, overhauls or to be cleaned after a transmission failure, you will save both time and money by having the option to service and adjust the converter at home or at the track! Want to change your combo at the track, all you need is another stator to drop in! Oh and you can save up to 4.5 lbs with our 9" version!

These new bolt together converters are made with a 2024 billet aluminum front cover, cast or optional billet aluminum stator with or without a sprag or diode. Of course, just like all ATI converters you get furnace brazed, American made, pump and turbines, as well as double o-ring seals. ATI offers many different stator options specific to your application. If you already have an ATI converter and would like to convert to a bolt together, that is an available option as well!

At ATI, we race what we sell! Our 8" & 9" Bolt Together Mopar converters are the result of in house research & development and track testing in our own Drag Pak Challenger and champions like Doug Duel!
