American dampers and transmission parts for racing

ATI Performance Products is an American company well known in the drag racing and muscle car scene. The brand is especially associated with the Super Damper, a crankshaft harmonic balancer used in everything from street cars to dedicated race engines. Alongside its dampers, ATI works with automatic transmissions and torque converters for competition use, including Powerglide and other classic American transmissions. The focus is on parts that handle high revs and hard launches.

ATI’s key products

Super Damper harmonic balancers are the core of the range. A harmonic balancer damps the torsional vibrations that occur in the crankshaft, protecting bearings, crank and accessories. ATI offers dampers in many diameters and designs for popular GM, Ford and Mopar V8 engines, including SFI-certified versions for motorsport. The range also includes pulleys, damper bolts and tools, as well as parts for automatic transmissions and torque converters. See each product for engine fitment.

Frequently asked questions

Why switch to a Super Damper?

A factory damper is designed for the stock engine. When the engine revs higher or makes more power, a Super Damper can control crankshaft vibration better and protect bearings and accessories.

Should I choose internal or external balance?

It depends on the engine. Some engines are internally balanced, others need a damper with added weight. Check the description on each product, or contact us with details of your engine.
