Detailed Description

This StrongArm tailgate lift support, part number 4990, is custom engineered to match the specified BMW fitment and provide smooth rear liftgate operation. It uses a pressurized cylinder design to help support the tailgate during opening and holding, with dimensions and end fittings that align with the listed BMW 525i and BMW 530i applications. StrongArm manufactures these lift supports beyond standard industry requirements to support long service life and consistent operation.

Compatible With 1993-1995 BMW 525i and 1994-1995 BMW 530i rear tailgate applications, StrongArm 4990 is a practical replacement when the original support no longer holds the hatch securely. The part number 4990 also appears in common interchange listings, including 510-861, 819-4222, 900303, B4990, B95936, SG102001, and SG102002.

What It Helps Solve

  • Tailgate that drops too quickly when opened
  • Rear hatch that will not stay raised
  • Weak or inconsistent lift assistance
  • Binding or uneven tailgate movement from worn support hardware
  • Reduced rear access convenience on BMW 525i and 530i models

Installation Notes and Tips

Verify the end fittings, compressed length, and extended length against the original support before installation. For safe and reliable operation, replace lift supports in pairs when the vehicle uses two supports on the same opening. Confirm the threaded 8mm and 10mm ball socket connection points match the vehicle mounting locations before final installation.

Quality Assurance

StrongArm lift supports are custom engineered and manufactured to exceed industry standards for smoother operation and longer-lasting performance. Part number 4990 is built for the listed BMW applications and follows the brand’s specific-fit replacement approach.
