Detailed Description

The Stabilus Lift-O-Mat hood lift support is built for precise motion control on the Chevrolet Corvette. Part number 5B-258643 uses a gas spring design with dynamic damping, where internal flow control is tuned to the application so the hood opens smoothly and closes with a controlled finish. This makes it a practical replacement for a worn or weak hood support on 2020-2025 Corvette models.

Stabilus engineered this support with ball socket ends, a 57 mm stroke, and a 410 N maximum force rating to match the hood’s movement requirements. The compact compressed length and extended length help maintain proper hood positioning while supporting consistent operation over time. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Hood that drops too quickly when opened
• Weak support that no longer holds the hood in position
• Uneven or jerky hood lift motion
• Excessive effort needed to raise the hood
• Controlled-stop issues at the end of hood travel

Installation Notes and Tips

Verify the ball socket attachment points and compare the compressed and extended lengths before installation. Replace the support only after safely securing the hood, then confirm smooth operation through the full opening and closing range. For 2020-2025 Chevrolet Corvette hood lift support replacement, confirm the part number 5B-258643 matches the original application before installation.

Quality Assurance

Stabilus is known for application-specific gas spring and lift support engineering, and the Lift-O-Mat line uses dynamic damping geometry to control extension speed and end-of-stroke movement. This part is built to OE-style specifications for the listed Corvette applications.
