Professional Products is famous for their large selection of high-performance street and race dampers. As a result of numerous requests, they have engineered two inexpensive (approx. $200) Powerforce+Plus 6.95-inch dampers for the early 1992-’02 (#90016) and the 2003-’09 (#90017) Dodge VIPER engines. A front timing cover change was made in ’03 necessitating the damper change. These dampers meet SFI specifications for extreme race applications on high-horsepower engines. The SFI Foundation establishes strict standards for specialty/performance auto and racing equipment.
Professional Products Powerforce+Plus Dodge VIPER dampers duplicate the factory damper dimensions for easy installation, are manufactured from forged 1045 steel, and include a keyway for those who prefer to add a keyslot in the crankshaft to provide extra safety. These dampers provide the best value and race ready quality when compared to anything on the market.
