Frequently Asked Questions
The Innovators West dampers are a friction style damper. Inside the damper is a wet friction clutch pack assembly. Spring Loaded inertia rings work in conjunction with clutches to provide the dampening action. There is a small amount of fluid inside that acts as a lubricant as well as dissipates heat. The free floating clutch pack design allows for a broad dampening range in a small package.
Unfortunately at this time we are not building custom products due to a backlog on making production parts. We are hopeful that we can add additional staff and machines to reduce that backlog and to be able to make custom parts in the future.
All Innovators West dampers exceed the SFI 18.1 standards. A SFI sticker is placed on the damper as well as the SFI number is stamped into the back of the damper case.
No, they are as light or lighter than OEM to reduce rotation weight.
Most dampers are marked every 5 degrees for 360 degrees and marked every 2 degrees from 30 degrees to 50 degrees. Serpentine dampers such as the Ford Mod Motor and GM LS dampers are not generally marked as the timing is computer controlled.
Yes, and we also offer dampers for street use, drag racing, marine applications, and off-road use as well.
Yes, all dampers have a industry standard dual keyway option available. The double keyway option requires that the factory or aftermarket crankshaft be removed from the engine and a second keyway cut into the snout of the crankshaft. DO NOT run a double keyed damper on a crankshaft without the double keys. Failure to the damper hub can happen without the supporting key in the broached keyway slot. The dual keyway option is for Supercharged or Extreme Duty Applications (typically over 750 rwhp). Without the double key modification your crankshaft in these high horsepower applications can lead to the failure of the damper hub and/or the single keyway which results in damage to the damper and the crankshaft snout.
For street and street/strip engines making under 750hp we recommend the damper be sent in for service every 6-7 years. For race engines or engines making over 750hp we recommend the dampers be sent in for service ever 1-2 years. We also recommend sending the damper in for service if your engine should experience any catastrophic damage that would send a large shock load through the damper (such as a broken rod or crank). The standard service fee is $95 plus return shipping charges. When shipping your damper in for service, please fill out and include our RMA form (PDF Format) with your shipment.
The standard service includes complete internal and external inspection, new SFI decal (if needed) and repolish of the outside of the damper. The internals of the damper are freshened and resealed. Any other repairs such as thread repairs or hard part replacement is additional and an estimate will be provided.
No, since the parts of the damper are manufactured in house and the fluid can not be bought off the shelf, we ask that the dampers be sent in to allow us to properly service the damper and inspect for any problems. When shipping your damper in for service, please fill out and include our RMA form (PDF Format) with your shipment.
Yes! Failure to lube the crankshaft snout during installation will likely cause galling on the snout and damper hub. It will also likely make it very difficult to get the damper fully seated, and if you do get it on, you may not be able to get if off easily.
We highly recommend using CMD Extreme Pressure Lube as sold in our store for this purpose.
Yes, we recommend that a damper installer tool be used to install any harmonic damper. This tool is available at most auto parts stores and may also be available for rent at the same auto parts stores.
