Product Details

The StrongArm 7021 is a pressurized gas cylinder lift support designed to smoothly raise and hold your vehicle's trunk lid in the open position. This precision-engineered component replaces worn or failed factory lift supports that cause heavy trunk lids to slam shut or fail to stay open.

Key Features:

  • Custom engineered and manufactured to exceed OEM industry standards
  • Pressurized gas cylinder design provides smooth, controlled trunk lid operation
  • High-quality construction for extended service life and reliable performance
  • Direct replacement for factory lift supports on compatible vehicles
  • Designed specifically for trunk lid applications

Important Installation Note: Lift supports should always be replaced in pairs to ensure balanced, safe operation and to prevent uneven wear on the replacement component. Using a single new lift support with a worn original can result in improper trunk lid function and reduced lifespan of the new part.

StrongArm lift supports are trusted by professional technicians and DIY mechanics for their consistent quality and durability across automotive applications.
