The 7300 Series damper is the damper of choice in all levels of professional stock car racing. The 7300 has also been adapted to some modified racing that uses coil-over shock absorbers. The 7300 is a simple, high-performance shock absorber that can be internally configured easily for any track and can be tuned externally with a single shaft adjuster. This shaft adjuster can affect compression, rebound, or both depending on the type of jet used. The 7300 also features a head valve piston that was born out of the desire to run lower gas pressures for grip and reduce “fade” while maintaining the performance of the shock. The head valve, depending on its build, can optimize the response time of the damper and allow the use of extremely low pressures to be used for reduction in friction and increased in grip and driver feel without the danger of cavitation. The reservoir in the 7300 is generous for good consistency over a large temperature range and features a reservoir piston that has been designed for low friction and maximum volume. A strong 2-piece body completes the design to maximize strength and minimize weight. This coupled with a strong chrome-moly shaft that is hard chromed, makes the 7300 a durable, high-performance damper with a proven track record of championships. Whether your a top Sprint Cup team or a Grassroots asphalt or dirt racer, the 7300 will give you maximum performance and reliability!
