Shock Options
	Adjustable Compression Reservoir (ACR)    An Adjustable Compression Reservoir (ACR) is optional on special applications for Pro Series, UltraCross and UltraSport based on available space requirements. If you purchase UltraCross or UltraSport shocks without the ACR option these can be added or retrofitted at some future date to allow you to fine-tune the compression.    Advantages: Works shocks are pressurized with nitrogen. Standard Works Performance shocks are gas-emulsion type, which means that the nitrogen is charged into the oil. The ACR unit is attached to the shock through a hose that transfers oil and helps dissipate heat. Inside the ACR unit is a polyurethane bladder that separates the nitrogen from the oil. There are two advantages to this; One is the oil capacity of the shock is increased, which aids in cooling the shock fluid which increases the service life of the oil; and second is that the compression and rebound valving will stay consistent under the most severe of conditions.
