Suspension systems are made from many component parts. The racing shock absorber is one of the more important components in the suspension system.

A shock absorber is a velocity sensitive hydraulic damping device which uses hydraulic pressure to resist movement of the suspension spring to limit and control the spring’s action. Wheel movements, or changes in the relationship between the axle and chassis are controlled primarily by the spring. The movement of the spring is motion that must be controlled or dampened by the shock absorber.

The shock absorber accomplishes control over a moving spring by a relatively simple method. Resistance to suspension movement is produced in the shock absorber when hydraulic fluid is forced through a series of valves and orifices during spring movement. The energy produced by the spring movement is dissipated by the shock in the form of heat energy and is passed off into the surrounding air.

In simple language, the racing shock is a heat dissipating machine, so whenever possible, allow fresh air to flow over it while in use.

The Pro-Shock designed and manufactured gas-cell shock does not need additional fluid added after assembly. A gas-cell shock properly filled at the time of assembly has virtually no lag and needs no further work by the customer. Our superior concepts at Pro Shocks guarantee you the results of cutting edge technology across all racing categories from IRL and CART, NASCAR Nextel Cup, World of Outlaws, Haulmark All Star sprints, USAC Silver Crown, sprints and midgets, WoO and UMP late models, Dirt Modifieds,  to our domestic AMCA, ASCF super sedans and modified production divisions, litre cars,  compacts, vintage speedcars and classic machines.

Grizzly Dyno Shocks can guarantee you a faster, smoother and trouble free ride across the dirt and asphalt tracks of Australia – and we speak from experience.
