NOTICE: WE INCLUDE THE BELT GUIDE WITH EVERY PURCHASE! If you're looking to protect your investment, don't be fooled about the conventional single strip elastomer dampers.

The 36-2 Trigger Wheel will have the missing teeth between the 9-10 when the engine is at top dead center and you're looking at the front of the engine. 

Bottom line is - you want a damper that is effective at multiple RPM ranges! You may have seen dampers that appear to be machined copies of the OEM pulley, these are static weighted, single striped and BONDED dampers that are only capable of being tuned for a single RPM range.

The ATI Torsional Super Damper® - the unconventional, unbonded elastomer Super Damper™ that is actually 2 dampers in 1 diameter.

In contrast, the ATI Super Damper employs a combination of O-rings and a unique, full-captured inertia ring to dampen harmful crankshaft vibrations. This configuration allows the damper to actually absorb crankshaft harmonics over a wide rpm range. It is not uncommon to find a Super Damper on race engines exceeding 9,000 rpm.

We not only recommend replacing both the hub bolt and keyway, we INCLUDE it with your purchase of your Super Damper® Harmonic Dampers! Simply choose the application or remove it with the NONE option. 
  • The 96-05 Miata is equipped with a trigger wheel that unfortunately can not be installed on your new ATI Damper - To solve this problem we have produced our own trigger wheel that can easily be installed to the ATI damper prior to installation.
  • Can be used on a long nose 1.6 engine when used with the 1.8 water pump and alternator pulleys.
  • Not compatible with short nose crank 1.6
  • Outer Diameter: 5.67" slightly larger than the OEM balancer.
  • If using a 1.6L you'll need to change your water pump and alternator pulley to a 1.8 configuration

ATI has designed a 5.5” damper - for the '94 - '05 Mazda Miata engine for high horsepower street & race use. This new design is a direct replacement for the stock OEM damper. The heart of this unit is the tried and true “damper within a damper” design that has put ATI ahead of the rest. The outer shell is machined to utilize the factory serpentine belt set-up

No trigger wheel:  For 1.6 or 1.8 engine using CAS
Modified 4 tooth trigger wheel:  For 96-05 using OEM triggering or aftermarket ECU that supports OE wheels.

    ATI damper for NA

    Posted by Chris Rummel on Apr 19th 2021

    This review is not so much on the ATI damper which is a great unit, but more as to why you should buy it from FAB9. I got it from Fab9 because I used to work at ATI and used to be the one selling them to Fab9, so I can personally tell you that they are selling them for the cheapest price you will get this damper for anywhere on the internet or otherwise. The miata damper is expensive for an ATI damper because it has a lot of extra machine work that goes into it and it doesn't have any common parts with other dampers. Bryan sells the damper for next to no margin at all, and not much more then an employee of ATI would get it for either. That is why when the time came to get mine, I got it from Fab9. Given that ATI can be hap hazard with getting shipments out, I had to wait for it and Fab9 had it drop shipped directly to my house and even gave me the option of picking it up. Either way they got it to me ASAP and I appreciate it. If you are in the market for this damper this is the place to get it.

    Quality parts, difficult installation

    Posted by Jacob Ortega on Aug 26th 2018

    High quality pieces, best price on the net, difficult installation mostly due to the woodruff key being difficult to get right when installing this piece. Mine ended up getting jammed behind during installation. HOWEVER, Fab9 was very helpful with this mishap and is sending me another key. Great company with great customer service.

    Haven't installed it yet but I can tell it's superb quality and the price is well worth it if you're pushing big power.
