A bump cap includes: a tubular main body part; and three or more protrusions provided at different positions in a circumferential direction of an inner circumference of the main body part. A plurality of protrusions are press-fit protrusions having a radial height higher than a radial height of the other protrusions, and the number of the press-fit protrusions are smaller than the number of the other protrusions, and the bump cap is configured to be mounted on an outer circumference of an outer shell of a shock absorber in state where the press-fit protrusions are pushed against the outer circumference of the outer shell.

A stroke sensor system includes a conductor, a coil which moves relative to the conductor and is fitted to one end side of the conductor; and a ferromagnetic body which is arranged on an end position side of the coil. A position of an end portion on one end side of the conductor in a state where a fitting ratio between the conductor and the coil is maximized is defined as the end position. The ferromagnetic body is located on an opposite side to the conductor with the coil interposed therebetween.

A vehicle strut assembly includes a boot and a coil spring. The boot has a vertical wall, a spring receiving portion and a centering portion projecting from the vertical wall. The coil spring has an end section, a transition section and a main section, the end section being fitted to the spring receiving portion encircling at least a portion of the vertical wall and defining a first radially inner diameter. The transition section has an increasing inner diameter extending from the end section to the main section. The main section defines a second radially inner diameter greater than the first radially inner diameter. The centering portion is positioned to contact a radially inner surface of the transition section of the coil spring restricting movement of the end section of the coil spring relative to the spring receiving portion of the boot.

A suspension thrust bearing device provides a lower support cap, an upper bearing cap and at least one bearing arranged between the caps. The lower support cap includes a rigid main body in contact with the bearing, and a flexible vibration damping seat delimiting a bearing surface for the upper end of a suspension ring. The vibration damping seat of the lower support cap is secured to the main body and is provided with at least one retaining hook extending at least in the radial direction and axially offset with respect to the bearing surface on the side opposite to the bearing.

A mounting eye (21) is fastened to a rod by pushing, partially or over an entire periphery, an outer periphery of a joint portion of a mounting eye into an annular groove of the rod. Accordingly, an axial length of a fastening portion can be set shorter than that of a related-art structure (screw fastening), thereby being capable of securing a stroke of the rod of a shock absorber in which the mounting eye is fastened to the rod.

A top cap assembly for a shock absorber includes a cap which has a first locking member connected to the center thereof, and an inner plate which has a second locking member connected to the center thereof. A first section of a piston rod extends through the first passage of the first locking member and is restricted by the first ridge of the first passage. A second section of the piston rod extends through the second passage of the second locking member and is restricted by the second ridge of the second passage. When installing the top cap assembly to different shock absorbers with different diameters, only the first locking member and the second locking member need to be replaced, and the cap and the inner plate do not need to be replaced.

A shock absorber for a vehicle suspension system may include a damper tube defining an axis, a rod operably coupled to the damper tube to be movable along the axis relative to the damper tube in response to jounce and rebound events, a dust boot operably coupled to the rod and extending along peripheral sides of the rod and at least a proximal end of the damper tube relative to the rod, the dust boot being movable with the rod, a target disposed on a damper bump cap operably coupled to the proximal end of the damper tube, and a measurement assembly affixed to the dust boot. The measurement assembly may include a PCB elongated parallel to the axis to track relative movement between the target and the measurement assembly responsive to the jounce and rebound events to generate ride height information based on the relative movement.
