Diesel Super Damper® Harmonic Dampers
Trusted by top shops like SoCal Diesel, Pure Diesel, East Coast Diesel, Diesel Innovations, Power Products Unlimited & more! Whether you have a mildly tuned street 5.9L Cummins or a 700” International Sled Puller, ATI has a damper to fit your needs. At ATI we’ve been building elastomer Super Dampers for nearly 30 years and we know how to build them right. ATI Diesel Dampers range from 6” to 10” in diameter and weigh between 10 to 36 lbs. They are tuned in-house to fit your exact application, and if you make a change, your Super Damper can change too. Each part is replaceable and rebuildable. No need to replace your entire damper at service intervals or if something happens. Don’t be fooled, treat your diesel engine like the professionals do, with an ATI Super Damper!

[8] Timing for a 466 John Deere will line up TDC on the bottom side of the damper at 180° so you will be under the engine to set from the 180° mark. Request a second 1/4” keyway to be cut for topside timing at no additional charge if requested at time of new order. The 619 timing will be set at TDC and straight up at 12 o’clock
