Fully assembled and factory filled with 1.000 viscosity silicone oil. Including springs which can be adjusted via a threaded collar. The excellent quality GPM shocks fit all cars of the HPI Baja 5 series, Carson Wild GP Attack and feature an extremely massive 7 mm rod. The GPM shocks cases and rod ends are completely made of aluminum and equipped with replaceable bushings at the upper and lower mounting points.The external volume control is more efficient than built-in versions with membrane or foam element. Compared with the technically similar solution of a floating balance piston inside of the shock absorber body there is the advantage that no length of the shock absorber is needed for the volume compensation. Furthermore the additional housing surface of the equalizing chamber helps in cooling the oil. Dimensions (front):distance between mounting holes (extended): 187 mm travel: 62 mm li> Outer diameter: 28 mm Mounting specifications: top and bottom 12 mm wide ball mount with 4 mm bore The GPM shocks are filled with 1.000 viscosity silicone oil. For a firmer setting 1.500 or higher viscosity silicone oil is recommended. If a softer setup is required, 900 or lower viscosity oil should be used.
