Detailed Description of StrongArm 4966 Lift Support

This trunk lid lift support is a specific fit for the Buick Riviera, designed to replace worn or failing gas struts. The steel outer cylinder and nylon ball socket ends provide durability and reliable connection points, while the 40-pound maximum force rating ensures the trunk lid remains open safely during use. The 13.48-inch compressed length and 22.88-inch extended length match the original equipment specifications, allowing for proper trunk lid movement without binding or excessive force. The inclusion of rubber and Teflon materials reduces friction and wear, contributing to longer service life. Note that this lift support does not include an internal rebound spring, which is consistent with the original design.

Common Issues Resolved by This Trunk Lid Lift Support

  • Difficulty holding the trunk lid open due to weak or broken struts
  • Unstable or jerky trunk lid movement when opening or closing
  • Excessive force required to lift the trunk lid
  • Corrosion or wear on original lift supports causing failure
  • Loose or damaged ball socket connections leading to rattling or detachment

Installation Notes and Tips

  • Ensure compatibility with Buick Riviera models before installation
  • Use appropriate tools to remove and install ball socket ends without damage
  • Check that the lift support is oriented correctly with compressed and extended lengths matching OEM specifications
  • Lubricate ball sockets if necessary to maintain smooth operation
  • Replace lift supports in pairs for balanced trunk lid performance
