1. A hydraulic lift actuator for adjusting a height of a vehicle, comprising:
a damper tube including a closed end;
a damper rod disposed at least partially within the damper tube and protruding therefrom opposite the closed end;
a sliding spring seat having a disc shape disposed annularly around the damper tube, the sliding spring seat including an upper surface facing away from the closed end and configured to engage an end of a coil spring disposed coaxially around the damper rod;
a support collar having a tubular shape disposed annularly around the damper tube and fixed to the sliding spring seat, wherein the support collar is configured to translate axially relative to the damper tube;
a lifting bracket connected to the support collar and protruding radially from the support collar; and
a hydraulic cylinder disposed adjacent and parallel to the damper tube, the hydraulic cylinder having a lift piston rod disposed at least partially within the hydraulic cylinder and extending outwardly therefrom toward the lifting bracket, wherein the lift piston rod is connected to the lifting bracket and configured to actuate the sliding spring seat between a retracted position and an extended position spaced apart from the closed end,
wherein the hydraulic lift actuator further includes a peg extending radially outwardly from the damper tube, wherein the support collar defines a slot extending in an axial direction and configured to receive the peg for preventing the sliding spring seat from rotating relative to the damper tube while allowing axial movement therebetween.
