Product Details

StrongArm 4078 is built as a trunk lid lift support for the Nissan Maxima, using a pressurized cylinder design with a steel outer body, rubber and Teflon materials, and nylon ball socket ends for secure attachment. The 79.0 maximum force rating and compact stroke dimensions help maintain consistent rear lid support during opening and closing. This part cross-references AMS Automotive 4078 for the same application.

Common Replacement Reasons

  • Trunk lid drops too quickly after release
  • Rear lid will not stay open
  • Weak or inconsistent lift support pressure
  • Binding, slow movement, or uneven trunk lid operation
  • Noise or wear at the lift support mounting points

Installation Notes

Verify vehicle fitment before installation on 2004-2008 Nissan Maxima models. Inspect the mounting ball studs and attachment points for wear before installing the new support. For safe, reliable trunk lid operation, replace lift supports in pairs when the vehicle uses a matched left/right setup.

Quality Assurance

StrongArm states that each lift support is custom engineered and manufactured beyond industry standards to support smoother operation and longer service life. Part number 4078 is built to meet the demands of trunk lid service on the Nissan Maxima.
