This adding of weight is nothing new in automotive applications. Chevy, Ford, and many cars install a harmonic balancer dampner on the nose end of the crankshaft to absorb some of the engine's harmonic vibrations (nodes). We originally designed this for our drag race cars to have more weight on the pulley end of the crankshaft to help EQUALIZE weight on both ends of the crankshaft. It stopped crank twist and aided the drag race cars as they left the starting line harder. Originally, we felt that a fluid, spring (Fisher type), or viscous dampner would improve the VW engine even more, however, all of our tests proved that none of those types of devices did anything more than what the Berg Equalizer was already providing.
The Berg Equalizers are extremely popular for sand drag 2nd gear starts and dune running. Offered in two sizes for high performance street cars or engines turning over 6000 RPM. One piece, solid steel construction assures concentricity and strength. Silver zinc finish with our exclusive hard anodized degree ring. Originated by Gene Berg in 1983. Made in USA by Gene Berg Enterprises.
