LIEBHERR PAIR OF GAS PRESSURE SPRINGS FOR ENGINE HOOD

Ask about product

A pair of gas pressure springs (gas struts) serves to support the open engine hood or service cover, maintaining constant lifting force through internal nitrogen charge and oil damping. This component is critical for personnel safety, as pressure loss or chromium-plated rod damage from corrosion and abrasion causes rapid hood collapse, creating direct hazard to service technicians. Planned replacement of both springs as a pair is mandatory—installing a single unit creates asymmetric loading that accelerates material fatigue and destroys the new component within months. This replacement prevents costly repairs to hinges and hood from uncontrolled drop impact, and eliminates risk of head injury during maintenance work. Use of original ball and fork ends ensures precise fit to machine frame, eliminating play and dangerous vibration during operation.
