Trunk Lid Lift Support for Infiniti G20

Restore steady trunk lid operation with this StrongArm trunk lid lift support, part number 4028. It is a specific-fit replacement engineered for 1991-1995 Infiniti G20 applications and built with a steel outer cylinder, nylon ball socket ends, and a 126.0 maximum force rating for controlled lift and hold.

StrongArm 4028 is a direct-fit trunk lid lift support for Infiniti G20 owners who need consistent rear compartment support and smoother opening action. The compact design measures 7.8 inches compressed and 10.44 inches extended, with a 2.64-inch stroke for the correct operating range.

  • StrongArm part number 4028
  • Steel outer cylinder with black finish
  • Nylon ball socket ends, 10mm at both ends
  • 126.0 maximum force rating

  • Stroke length: 2.64 in
  • Rubber and Teflon materials for internal sealing and movement control

Detailed Description

This StrongArm trunk lid lift support is engineered for the rear compartment on 1991-1995 Infiniti G20 models. As a pressurized cylinder, it helps maintain trunk lid position during opening and closing while supporting smoother, more controlled movement. The specific-fit design, 10mm nylon ball socket ends, and compact dimensions make part number 4028 a practical replacement when the original support loses pressure or no longer holds the lid properly. This part cross-references AMS Automotive 4028 for the same application.

What It Helps Fix

  • Trunk lid that drops instead of staying open
  • Weak or slow lift action on the rear compartment lid
  • Uneven or inconsistent trunk opening effort
  • Noisy or rough movement from a worn lift support
  • Loss of support pressure in Infiniti G20 trunk lid applications

Installation Notes and Tips

Verify the existing support’s compressed and extended lengths, end style, and mounting points before installation. For proper operation and balanced support, replace lift supports in pairs when the vehicle uses two supports on the same lid. Confirm the 10mm ball socket connection and match the specific-fit application to the 1991-1995 Infiniti G20 before installation.

Quality Assurance

StrongArm manufactures lift supports beyond industry standards and custom engineers each unit for smoother operation and longer service life. Part number 4028 is built to meet the demands of trunk lid support use on the Infiniti G20.
