A shock absorber for a vehicle suspension system may include a damper tube having an axis defining an axial direction extending between a first end and a second end, a bumper cap, and a dust gaiter operably coupled to the bumper cap. The bumper cap may have a cover portion and a retention portion. The cover portion may be operably coupled to the second end of the damper tube, and the retention portion may extend along a lateral periphery of the damper tube to an opposite end of the bumper cap relative to the cover portion. The retention portion may include a continuous ring at a distal end of the bumper cap relative to the cover portion to define a limit for movement of the dust gaiter along the bumper cap in the axial direction. The continuous ring may be retained by a plurality of fixed fingers that extend from the cover portion to the continuous ring. A movable finger is disposed between each of the fixed fingers, each instance of the movable finger having a radially extending locking tab to engage the dust gaiter. Each instance of the moveable finger has a radial deflection rate of less than about 8 N/mm.

A temperature compensating shock strut health indicator system for use with a shock strut comprises a visual indicator comprising a plurality of sectors and a pointer configured to rotate with respect to the visual indicator to point to one of the plurality of sectors. The sector to which the pointer points to is dependent on the shock strut stroke (i.e., the position of the piston with respect to the cylinder). In various embodiments, the visual indicator includes various rings that correspond to a different temperature compensated ideal stroke whereby a crew member can correspond the pointer to the appropriate ring depending on ambient temperature. In various embodiments, the pointer comprises a temperature sensitive material configured to cause the pointer to rotate with respect to the visual indicator to actively compensate for temperature.

A bumper cap for a damper, the damper including an outer tube with a tube end. A rod extending through the tube end. The damper including a damping fluid, such as a hydraulic oil, that is movable within the damper in response to movement of the rod to provide a damping effect. The bumper cap has a cup shaped body having a side wall and a base, the side wall having an inner surface and an outer surface, the inner surface having a dimension that is sized to be press fit over the outer tube. The base of the bumper cap has a through hole in the base, the through hole configured to have the rod pass therethrough. The base has at least one fluid passage extending away from the through hole that is in fluid communication with a fluid reservoir in the side wall.
