Secondary dampening assembly for shock absorber

A shock absorber assembly comprising:

• a pressure tube extending between an upper end and a lower end;
• a rod guide disposed adjacent said upper end of said pressure tube;
• a compression valve assembly disposed adjacent to said lower end of said pressure tube;
• a piston assembly disposed in said pressure tube between said rod guide and said compression valve assembly;
• a rod operatively attached to said piston assembly and having a first end supported by said rod guide so as to concentrically align said rod with said pressure tube, and a second end disposed within said pressure tube;
• an extender coupled to said second end of said rod;
• a hydraulic stop piston having a diameter less than a diameter of said pressure tube, said hydraulic stop piston carried by said extender with a gap defined radially between said hydraulic stop piston and said extender to allow radial movement;
• a hydraulic stop sleeve disposed within said pressure tube such that said hydraulic stop sleeve engages said pressure tube, said hydraulic stop sleeve having an open end for receiving said hydraulic stop piston and a closed end and defining a non-tapered bore shaped to receive said hydraulic stop piston;
• and
• wherein said hydraulic stop sleeve has a flow groove extending longitudinally along an inner surface of said hydraulic stop sleeve.
