1. A shock absorber comprising:
an inner tube defining an inner volume;
a piston slidably disposed in the inner tube, the piston dividing the inner volume of the inner tube into a rebound working chamber and a compression working chamber;
an intermediate tube on the inner tube defining an intermediate chamber between the inner tube and the intermediate tube, the intermediate chamber being in fluid communication with the inner volume of the inner tube;
an outer tube;
the inner tube and the intermediate tube being in the outer tube, the outer tube defining a reserve chamber between the outer tube and the intermediate tube;
a valve fluidly connecting the intermediate chamber and the reserve chamber;
a transfer ring fluidly connecting the intermediate chamber and the valve;
the transfer ring including a body, a first seal positioned at a first end of the body, a second seal positioned at an opposite second end of the body, and a connector;
the first seal being between the body and the intermediate tube, a second seal between the body and the valve, and the connector being connected to the first seal and the second seal, the body including a surface defining a bore extending between the first end and the second end to fluidly interconnect the intermediate chamber and the valve, the body including an internal channel spaced apart from the surface of the bore, the connector extending through the channel from the first seal to the second seal.
