Claim 8:
9. A shock absorber assembly, comprising:
a shock absorber comprising:
a cylinder having a first end and a second end;
a piston rod extending through the first end of the cylinder;
a cylinder piston disposed in the cylinder, the cylinder piston being connected to an end of the piston rod;
a reservoir fluidly connected to the second end of the cylinder,
the reservoir and the cylinder defining a fluid chamber for receiving a hydraulic fluid;
a reservoir base valve disposed in the fluid chamber, the reservoir base valve separating the fluid chamber into a first portion and a second portion, the reservoir base valve defining a plurality of passages fluidly connecting the first portion and the second portion, the plurality of passages including at least one compression passage and at least one rebound passage;
a bypass channel fluidly connecting the first portion of the fluid chamber to the second portion of the fluid chamber, the bypass channel being formed by the reservoir base valve;
a bypass valve disposed at least partially in the fluid chamber, the bypass valve being configured to selectively control fluid flow through the bypass channel, the bypass valve being selectively movable between at least an open position and a closed position, the bypass valve defining the bypass channel therethrough; and
a check valve disposed in the bypass channel, the check valve being configured to:
permit fluid flow through the bypass channel from the first portion to the second portion, and
impede fluid flow through the bypass channel from the second portion to the first portion; and

a coil spring disposed around the cylinder of the shock absorber.
