ATI Performance Products is proud to introduce new lightweight steel modular trigger shells available in a variety of tooth counts and compatible with Motec, Holley, Haltech, BS3, AEM & other stand-alone engine management systems! These fully CNC-machined, bolt-on trigger shells fit our 7”, 3-ring dampers, and require a non-serpentine custom aluminum outer shell (Part #916518). These shells can be ordered & installed on a new damper or retrofitted onto your current 7” ATI Super Damper. If installed on new damper, deduct $100.

ATI currently offers the following tooth counts:

• 916517 TRIGGER WHEEL - STEEL BOLT ON – 7” - 12 TEETH & -1 AVAILABLE
• 916511 TRIGGER WHEEL - STEEL BOLT ON – 7” - 24 TEETH & -1 AVAILABLE
• 916512 TRIGGER WHEEL - STEEL BOLT ON – 7” - 32 TEETH & -1 AVAILABLE
• 916513 TRIGGER WHEEL - STEEL BOLT ON – 7” - 36 TEETH & -1 AVAILABLE
• 916516 TRIGGER WHEEL - STEEL BOLT ON – 7” - 60 TEETH & -1 OR 2 AVAILABLE
• 916514 TRIGGER WHEEL - STEEL BOLT ON – 7” - 24 TEETH - BIG STUFF PATTERN
• 916515 TRIGGER WHEEL - STEEL BOLT ON – 7” - 24 TEETH - AEM PATTERN

All trigger wheels are sold without a missing tooth and ATI will deduct $40 if no modifications are required. If your application requires a tooth to be removed, at the time of order, ATI will remove them at whichever degree mark the customer specifies and will rebalance the trigger wheel once the tooth is removed.

OEM dampers are optimally tuned to a narrow band of “perceived normal driving conditions” and do not perform well outside of those limits. The ATI Super Damper can handle any engine speeds and driving conditions that get thrown at it to better protect your engine. ATI Super Dampers provide balanced dampening of torsional crankshaft vibrations through all RPM ranges especially during competition use.
