## Description

(Street Series - O.D 6-3/8" - 5.5LBS - Bore Dia. 1.590min/1.592max - Aluminum Housing) Built for the (89-94) Plymouth 1G Eclipse-Talon... A good aftermarket damper protects your crank. Fluidampr is in a class all by itself, because it is designed to provide maximum control of all engine harmonic vibrations, regardless of the rpm at which they occur and regardless of the crankshaft's natural frequency. This translates to maximum protection of the crank, main bearings, related engine components and more consistent power output. Also, Fluidampr is maintenance and repair free. Fluidampr is effective on both race and street applications. Other dampers on the market use rubber or elastomer as the insulator for the internal flywheel. Rubber deteriorates and wears down from repeated movements. In laymans terms, the more you work it, the weaker it will get. The inertia ring that balances an elastomeric damper becomes unstable when the o-rings start to wear. Think of it this way, what does a car wheel feel like when it looses one of its balancing weights? How would a fan missing a blade function? A damper with worn o-rings can unbalance a crankshaft and destroy it. The reason car manufactures install elastomer dampers at the factory is not for performance but for cost. The rubber dampers are cheaper and easier to make. Scroll over the picture on the right to see what makes the Fluidampr unique.

### ⭐⭐⭐⭐⭐ 







  
  
    Great design.
  

*by S***O on Reviewed in the United States on September 22, 2016*

I like the quality and engineering dedicated to the pulley, but, be warned some 4G63T motors need to have the timing cover shaved a bit for clearance, I have yet to install the pulley on my 1990 eagle talon tsi, and they say in the instructions that it may be necessary to trim the timing cover, I really hope thats not the case, I may end up returning the pulley for the updated version that clears the early dsm timing cover correctly, I heard the company updated the design so maybe I got a new old stock pulley, "sigh" regardless I'm going to contact the company and see if thats the case, maybe they can ship me a new one in turn of this one, I don't want to risk damaging my timing cover otherwise I like the concept and design if it goes on smoothly [without contacting my t belt cover] I'll update the rating of the product and let you all know.Update: well it turns out they don't make one that clears the stock cover, because the 2g dsm timing cover does not have a ring around the cover like the 1g 6 bolt and 1g 7 bolt motors do, and after looking at my stock cover it looks like it's not that hard to do, just take your time and use a mini rotary tool, and be careful, I suppose if your a 1g owner or a 2g with a 6 bolt motor make sure you adequately trim the timing cover 2g motors don't really have this issue but do check it anyway.
