Product Details

The StrongArm 6578 Trunk Lid Lift Support is a precision-engineered gas strut designed to provide smooth, reliable operation for trunk lids in automotive applications. This pressurized cylinder is custom-manufactured to exceed industry standards, delivering consistent lifting force and controlled motion for safe trunk operation.

Key Features:

  • Custom-engineered pressurized gas cylinder for optimal performance
  • Manufactured beyond industry standards for extended service life
  • Provides smooth, controlled trunk lid operation
  • Direct replacement for worn or failed original equipment lift supports
  • Designed for reliable, long-lasting performance

Important Installation Note: Lift supports should always be replaced in pairs to ensure balanced, safe support and prevent premature wear on the replacement component. Installing only one new lift support can create uneven force distribution and compromise trunk lid safety.

StrongArm lift supports are engineered to restore proper trunk lid function, eliminating the need to manually prop open your trunk and ensuring safe operation every time you access your cargo area.

best price

Fast shipping and saved $60 on a $399 item. However you have to verify your part #'s with the vendor. The part discription on autoplicity sometimes is not what you get. I ordered an item that said it was an O2 plug and bung but when it showed up it was just the bung plug sold separate and customer service basically said it was my bad for not checking for a more accurate discription on the Allstar web site.

I haven't received my order yet but I am satisfied at how fast the order was processed and shipped. The website was very easy to navigate and best of all the prices were hard to beat. I believe I will be visiting this site again.
