Reservoir shocks are recommended for aggressive off-road use.
Making the proper shock choice would be determined by the individual's use. A reservoir would be recommended for long periods of off highway use at high speed. This would mean extended use in washboard roads, fire roads or just wanting to keep consistent damping during heavy off highway use. By adding oil volume and addtional cooling surface area, a reservoir can extend service life, and vehicle control during extended off road use. The addtion of a reservoir also gives the shock better extened and compressed travel or range by moving the dividing piston and gas compartment into the reservoir tube.
