Detailed Product Overview

StrongArm 4358 is a pressurized lift support built for rear hatch and tailgate use on 2000-2007 Ford Focus and 2004-2007 Mazda 6 models. The cylinder is custom engineered to deliver steady lift assistance and smoother operation than a worn or weak support. If your Ford Focus or Mazda 6 tailgate drops too quickly, stays open inconsistently, or requires extra effort to raise, this replacement support addresses the gas strut that controls hatch movement.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. StrongArm manufactures its lift supports to exceed typical industry standards for durability and operating consistency, making part number 4358 a practical OE-style replacement for rear liftgate service.

What This Part Helps Fix

  • Tailgate or hatch that will not stay open
  • Rear liftgate dropping faster than normal
  • Weak or uneven opening effort
  • Noise or rough movement from a worn gas strut
  • Loss of support at the rear hatch on a Ford Focus or Mazda 6

Installation Notes and Tips

Verify the ball socket end style and compressed/extended length before installation. This StrongArm 4358 uses 10 mm nylon ball socket ends at both connections and is a specific-fit part, so matching the vehicle application is important. For best results, inspect the mounting points and surrounding hardware for wear before installing the new support.

Quality Assurance

StrongArm states that each lift support is custom engineered and manufactured beyond industry standards for smoother operation and longer service life. Part number 4358 is built as a direct replacement for the listed Ford Focus and Mazda 6 applications.
