ATI Super Dampers, Harmonic Balancers and Pulleys

Shop ATI Performance Products Super Dampers, harmonic balancers, crank hubs, pulleys, elastomer service kits, installation tools, and exact engine hardware by manufacturer part number. Match every damper to the engine family, crankshaft, internal or external balance requirement, hub, shell, diameter, belt grooves, accessory drive, trigger arrangement, and intended operating range.

ATI Super Dampers

ATI Super Dampers use a tunable inertia-ring and elastomer design to control crankshaft torsional vibration in street, drag, road-race, and competition engines. The correct assembly is exact to the crankshaft and front-drive configuration, so similar diameter or groove count does not establish interchangeability.

Engine and Vehicle Applications

The catalog includes application-specific configurations for GM LS and LT engines, Ford modular and Coyote engines, Mopar Hemi combinations, import performance engines, and diesel platforms. Vehicle filters are used only where ATI supplies a defensible year, make, and model relationship. Engine-only products remain outside YMM results until exact vehicle coverage is established.

Pulleys and Service Components

Supercharger pulleys, crank pin kits, elastomer kits, bolts, dowels, installation studs, and puller or installer tools must match the exact ATI damper, hub, thread, interface, and service operation. Confirm belts, spacers, keys, washers, and companion hardware separately.

How to Choose the Correct ATI Component

• Match the exact ATI manufacturer part number
• Confirm engine family, crankshaft snout, keyway, trigger arrangement, and balance requirement
• Verify hub and shell construction, outside diameter, ring count, and SFI requirements
• Match every belt groove, accessory pulley, supercharger ratio, and clearance requirement
• Use ATI's current installer, fastener, washer, spacer, torque, runout, and service instructions

Frequently Asked Questions

How do I confirm an ATI Super Damper fits my engine?
Match the exact part number, engine and crankshaft family, balance type, crank snout, hub, keyway, trigger requirements, diameter, groove arrangement, and every ATI application note.

Can I choose a damper by diameter and belt grooves alone?
No. Similar-looking dampers can use different hubs, balance, offsets, keyways, trigger arrangements, and drive locations. Confirm the complete engine and front-drive specification.

Are ATI Super Dampers serviceable?
ATI Super Dampers are designed to be inspected and serviced. Follow ATI's current limits and procedure for the shell, hub, fasteners, inertia ring, and elastomers.

What installation checks matter most?
Use the correct installer and fasteners, verify hub and crank condition, key and spacer placement, pulley alignment, runout, belt routing, clearance, and final torque. Never hammer a damper onto the crankshaft.
