A vehicle suspension damper including: a cylinder; a piston assembly; and an adjuster, wherein the piston assembly compresses fluid as it moves within the cylinder and the adjuster obstructs fluid flow from a first side of a damping piston of the piston assembly to a second side of the damping piston.

An adjustment wheel arrangement for a shock absorber with a first adjustment wheel which is configured to connect in a torque-proof fashion to an adjustment tube of a piston rod of the shock absorber, and a second adjustment wheel which is configured to connect in a torque-proof fashion to an adjustment rod extending through the adjustment tube. The first adjustment wheel and the second adjustment wheel can be twisted relative to each other by means of a push-twist connection but are or can be connected by form-fit to each other in the axial direction. The push-twist connection is configured in the manner of a key-lock, such that the first adjustment wheel and the second adjustment wheel can be connected to or separated from each other only in a single relative orientation.

A damper assembly includes a piston and cylinder type damper with a piston (14) mounted for reciprocal movement in a cylinder (10) containing damping fluid. The piston (14) is acted on by a piston rod (11) which includes a reaction surface for engaging the piston. The cross-sectional area of the reaction surface is designed to be significantly greater than the cross-sectional area of the piston rod (11) in order to spread the load exerted on the piston (14). Also, the piston (14) is designed to engage the piston rod (11) at its inner end in a manner that provides lateral guidance for the inner end of the piston rod in its movement in the cylinder (10).
