Detailed Description

StrongArm 4321 is engineered as a direct-fit lift support for 1996-2004 Nissan Pathfinder and 1997-2000 INFINITI QX4 models, with INFINITI QX4 coverage noted through 09/1999. This part number 4321 is built to match the required length, stroke, and force for the application, helping the hood, hatch, or rear glass move with controlled support. The steel cylinder construction and nylon ball socket end help deliver consistent operation in daily use.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. StrongArm lift supports are custom engineered and manufactured to exceed typical industry standards for smoother operation and longer service life. Part number 4321 is a direct replacement choice for owners searching for a Nissan Pathfinder lift support or INFINITI QX4 lift support by exact fitment.

What It Helps Fix

• Rear glass or hatch that will not stay open
• Liftgate that drops too quickly when opened
• Weak or inconsistent opening support
• Worn gas strut performance on aging rear lift systems
• Difficulty accessing cargo area due to failing support force

Installation Notes and Tips

Verify the end fittings and measurements against the original support before installation. For best results, replace lift supports in pairs so the opening force remains balanced across the hatch or rear glass. Confirm the vehicle application by year and model before ordering StrongArm 4321 for a 1996-2004 Nissan Pathfinder or 1997-2000 INFINITI QX4.

Quality Assurance

StrongArm manufactures this lift support beyond typical industry standards for consistent fit and smoother operation. The custom-engineered design supports reliable performance in the specified Pathfinder and QX4 applications.
