Safe Disposal of Heavy-Duty Shocks

Disposal Instructions

Appropriate protective measures, such as wearing safety glasses and protective gloves, should be taken when removing oil and gas from discarded and defective shock absorbers.


1. Secure the shock absorber in a horizontal position. Fully extend the piston rod prior to drilling the unit.
(see FIG. #A).
2. Using a 1/8” (3mm) drill bit, drill a hole in a downward direction approximately 1.0” (25mm) from the bottom of the shock absorber to a depth of about 1.0” (25mm) (see FIG. #B).
3. Drill a second hole of about 1/8” (3mm) at 2.0” (50mm) from the top of the shock absorber to depth of about 1.0” (25mm), in order to allow all of the oil to flow out.
4. By moving the piston rod in and out, begin stroking the unit to completely purge the oil from the cylinder of the unit (See FIG. #C).
