Install the shock onto your frame using the appropriate hardware. Do NOT use old or worn hardware & do NOT use bent or rusted fasteners.
Remove air cap, depress the schrader air valve while pushing down on the bike to fully collapse the shock.
While shock is collapsed, check for any interference or contact points on the frame, shock, tire, and linkage. Make sure there are NO contact points, if there are, you may have the wrong size shock and or a defective or damaged frame.
Run the shock a few times through its travel, check for any binding that may be coming from the mounting hardware and the shock.
After everything checks out and there aren’t any clearance issues, inflate the shock to 50 psi and cycle it through the travel a few times then inflate the shock to the recommended air pressure for your weight and riding conditions (200-300 psi). Then bounce on the bike compressing the shock multiple
times making sure the negative air chamber is set to the positive air chamber. Set SAG according to the recommended setting and enjoy your ride!
After your first trail ride on your new shock, check all fasteners that may have come loose.
