Determining location-

Generally speaking the JounceShock should be located such that the cylinder (large end) is permanently attached to the chassis of the vehicle. The position of the JounceShock is determined by the vehicle suspension. The shaft end (small end) of the JounceShock should be driven by an area of the suspension that is strong enough for the forces that will be seen. Typically this means that the shaft end will be contacting the axle housing, lower control arm, or other major suspension component. In most applications, the Jounceshock is positioned so that it is engaged in the last 1/4 to 1/3 of suspension travel. The JounceShock should determine the limit of the suspension travel in compression, the maximum desired suspension position should coincide with the JounceShock being fully compressed. Since the highest forces are experienced when the JounceShock is fully compressed, the unit should be mounted parallel to the direction that the suspension is moving at full compression or as close to that as possible. This limits the side loading that the JounceShock experiences when the pressures are at their highest which in turn increases durability and load capacity.
