Overall Assessment

Customers praised the product for its problem solving abilities such as repairing engine vibrations and balancing their vehicles. Not only is it recognised for its usability, but its perfect fit and quality in comparison to more expensive alternatives is also appreciated. The product's positive effect on reducing stress on the crankshaft assembly, smoothing revolutions over RPM range, and potentially extending engine life is also emphasized. Its easy installation and high quality got noticeable mentions, making it a preferred choice over other brands. The product delivers performance as advertised, and it's considered a good dealer notwithstanding its lower price.

As with most front drive items, it was necessary to shim the WP pulley to line up. Maybe 0.050". The finish of this part is not as good as a REAL Fluidampr, but a close second and much cheaper. I am using it on a vintage sprint car so it won't see much more than 6200.

Less stress on the crankshaft assembly and vibrations smoothed out over the RPM range up to 18,000 rpm's. Smoother running engine, more horsepower available, & longer engine life!
