Detailed Product Overview

StrongArm 6407 is a pressurized trunk lid lift support built for the rear compartment on the 2004, 2005, and 2006 Kia Amanti. The cylinder uses a steel outer body, nylon ball socket ends, and internal materials selected for smooth operation and long service life. With a 19.0 mm cylinder outside diameter and 8.0 mm inner shaft diameter, this lift support is sized for direct replacement service on the specified application. This part cross-references Monroe Shocks & Struts (e.g., 819-6510, E6407) for the same application.

For buyers searching for a 2004 Kia Amanti trunk lid lift support, 2005 Kia Amanti lift support, or 2006 Kia Amanti rear compartment support, StrongArm 6407 provides the fitment and dimensions needed for the listed vehicle range. The part number 6407 is also a useful reference when matching an OE-style trunk support for Kia Amanti rear lid service.

Common Problems This Part Can Address

  • Trunk lid that drops too quickly when opened
  • Rear compartment lid that will not stay raised
  • Weak or inconsistent lift assistance
  • Binding or uneven trunk lid movement
  • Loss of support from a worn pressurized cylinder

Installation Notes and Tips

Verify vehicle fitment before installation and confirm the ball socket end style matches the existing mounting points. StrongArm recommends replacing lift supports in pairs to maintain balanced operation and reliable support of the trunk lid. After installation, cycle the trunk lid several times to confirm smooth movement and secure engagement at both ends.

Quality Assurance

StrongArm lift supports are custom engineered and manufactured to exceed industry standards for smoother operation and longer-lasting performance. StrongArm 6407 is built as a specific-fit replacement for the listed Kia Amanti applications.
