ATI Performance Transmissions & Super Dampers

ATI Performance Products has been at the forefront of race-winning drivetrain engineering since the 1980s, with over a dozen U.S. patents backing a catalog built for serious competition. From drag racing's top professional classes down to weekend street/strip builds, ATI components are trusted when reliability and power transfer are non-negotiable.

Popular Upgrades

The ATI Super Damper is the gold standard in harmonic balancer technology, reducing crankshaft torsional vibration to protect engine components under high-RPM loads. The Superglide transmission series and Treemaster Converters are proven choices for automatic-equipped performance builds, while the Compu-Flow Valve Bodies add precision shift control. Flexplates, adapter kits, and internal transmission components round out the catalog for builders needing complete drivetrain solutions.

Are ATI Super Dampers street legal?

Yes. ATI Super Dampers are SFI-certified and designed for both street and strip use. They are a direct replacement for the factory harmonic balancer, offering significant improvements in durability and protection without requiring any special accommodations for street driving.

What vehicles does ATI support?

ATI's catalog covers a broad range of domestic V8 and V6 platforms, including popular GM, Ford, and Chrysler applications. Specific fitment varies by product line, so check the product detail pages for your engine family and displacement.
