7300 Series Damper

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 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!

 7700 Thru-Rod shock

The 7700 Thru-Rod shock is the latest development in short track shock technology. The thru-rod design eliminates the gas pressure feel entirely. Thru-Rod design eliminates any displaced fluid, so the need for a separate head valve or nitrogen chamber is no longer needed. This drastically reduces running friction and improves consistency by eliminating the effect of rising gas pressure commonly associated with gas shocks. Also by eliminating the head valve, this reduces the amount of pieces and flow paths the fluid must take. This allows the shock to change direction quicker, resulting in more mechanical grip.

 7500 Single Adjustable

The 7500SA has been run for the past 20 years in multiple racing markets. One of the first ever rebuildable shocks, the 7500SA is a quality single adjustable shock that uses standard Penske parts. CNC machined to hold the tightest tolerances, the 7500SA is the most repeatable aluminum bodied shock on the market. Cost effective and reliable, this is the best single adjustable shock on the market. Optional internal jets allows the customer to choose either compression, rebound, or open jet configurations.

The design features a separator piston in the reservoir which has been proven to maintain damper performance and improve response, as well as a single shaft adjuster if desired. The 7500 is available in both coilover and non coil-over style in all body lengths. There are also several options for body cap style which allows its use in many regulated spec series that require a sealed shock. Due to its design, the 7500 can be made to fit many applications simply by changing its modular body cap and eyelets. Currently, the 7500 is being used in all forms of Short Track Racing (NASCAR Weekly Racing Series, USAC Sprints and Midgets, Asphalt and Dirt Late Models and Modifieds).
