ATI Offers the Industry's First 8" & 9" Bolt Together Converters for Chrysler / Mopar 904 and 727 Transmissions!

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!

New ATI Super Damper for Cummins Onan 12.5 KW Generator with Isuzu 3LD1 3-Cylinder Engines - 125 - Part #917182

ATI Performance Products is proud to introduce its Super Damper for the Isuzu 3LD1 3-cylinder diesel engine found in popular Cummins Onan 12.5KW Generators. ATI Part #917182 is a 4.93-inch steel shell damper with a single V-belt drive (125mm x 18mm replacement size) in the outer shell and is a direct replacement for OEM Cummins Onan Crankshaft Pulley Part #512-0261 and Isuzu Part #8-97226831-0. The damper comes marked for TDC, features a single OEM-sized .276-inch keyway in the steel hub, and exceeds SFI 18.1 Certification—just because that is the only way we know how to build them!

The ATI Super Damper is synonymous with the highest quality dampers found in the aftermarket high performance engine world. OEM dampers are optimally tuned to a narrow band of “perceived normal operating conditions” and do not perform well outside of those limits. For example, the OEM damper does not perform well during start-up and shutdown of your generator. The OEM damper is also a common single elastomer strip design that holds the v-belt drive to the rest of the damper. When the rubber fails, the damper fails and possibly your engine fails as well. The ATI Super Damper can handle any engine speeds and operating conditions that get thrown at it to better protect your generator engine, and even better, you can have it rebuilt during an engine work or overhaul. The ATI Super Damper provides balanced dampening of torsional crankshaft vibrations through all RPM ranges!
