More About BHJ Dynamics
Pit Stop USA is The Online Motorsports Superstore! BHJ Harmonic Dampers have been second to none since manufacturing began in 1986. BHJ offers Street Performance and SFI Certified Dampers for domestic and import applications. B-H-J harmonic dampers meet all S.F.I. and racing association specifications. B-H-J Harmonic Dampers or "Torsional Vibration Dampers" offer the most precise and advanced execution of the proven elastomer design. BHJ precision harmonic dampers offer maximum protection from torsional, axial, and radial crankshaft vibrations while adding minimum weight to the rotating assembly. Elastomer-type dampers are preferred by most engine designers because of their durability, superior high-frequency damping qualities, and their ability to dampen all types of vibrations: Torsional, axial and radial. All-steel dampers have been manufactured by BHJ Products longer than any other company in the industry. They have proven their merit in thousands of applications, including off-shore boats, NASCAR Nextel Cup and NASCAR Busch Grand National stock cars, Short Track, Super Modified, Pro Stock and other drag racing cars, Formula 5000, Indy Cars, and street-driven grocery-getters. BHJ harmonic dampers are custom designed to meet each specific application. All BHJ dampers feature a TDC mark and are marked in degrees from 0 to 50 in 2-degree increments as well as 90-degree marks for valve settings. We feature BHJ Harmonic Dampers at low everyday prices!
