A shock-absorbing device (10) includes an inner cylinder (22) surournded by an outer tube (12) whose ends are enclosed by end caps (14, 128). A piston (42) within the cylinder (22) forces hydraulic fluid through holes (106-116). A metering sleeve (130) slidable over the cylinder (22) includes cross-cut openings (132-142) therein defining rectangularly-shaped metering orifices which selectively close off the openings (106-116) in the cylinder (22) to adjust the flow of hydraulic fluid, and thereby alter the shock-absorbing characteristics of the device. The cross-cut openings (132-142) may be formed by passing a cutting element along a straight stroke through a side of the metering sleeve (130) at a depth sufficient to create an orifice in the inner wall of the sleeve (130).
