Detailed Description

Stabilus 5B-677601 is a gas-charged lift support for power trunk opening and closing systems. It is specified for 2017-2020 Genesis G80 and 2014-2016 Hyundai Genesis, making it a focused replacement for vehicles that rely on controlled trunk movement and consistent lift assistance. The part number 5B-677601 also cross-references 81771-B1010 and 81771-B1011 for the same application.

With a 370 N force rating, 236.5 mm compressed length, and 379 mm extended length, this support is sized to match the original trunk support geometry. The plastic socket end connections and 10 mm attachment diameter help maintain OE-style fitment on the listed Genesis G80 and Hyundai Genesis applications.

What It Helps Fix

• Trunk lid that drops too quickly
• Weak or inconsistent power trunk opening
• Trunk support that no longer holds the lid in position
• Binding or poor movement from a worn gas strut
• Reduced lift assistance on the rear trunk opening system

Installation Notes and Tips

Verify the existing support’s compressed length, extended length, force rating, and socket style before installation. This part uses plastic socket connections at both ends, so confirm the mounting points match the original hardware on your vehicle. For best results, replace supports in matched condition when the trunk lid no longer opens or closes evenly.

Compatible With 2017-2020 Genesis G80, power trunk opening/closing, and 2014-2016 Hyundai Genesis, power trunk opening/closing. Use the vehicle’s original mounting points and compare the OE part number before installation.
