StrongArm 4002 Trunk Lid Lift Support

StrongArm 4002 is a specific-fit trunk lid lift support for select GM vehicles from the late 1970s and early 1980s. It restores controlled opening and steady hold for the trunk lid on applications such as Buick Century, Buick LeSabre, Oldsmobile 98, and Chevrolet Caprice.

Key Features

  • Specific-fit trunk lid lift support for direct application matching
  • Extended length: 9.82 in.; compressed length: 6.36 in.
  • Stroke length: 3.46 in. for controlled lift travel
  • Maximum force rating: 191.0
  • Black steel outer cylinder for durable construction
  • Blade with retainer ends, .312 in. hole at both ends
  • Rubber and Teflon materials for smoother operation and wear resistance
  • Cross-references AMS Automotive 4002 for the same application

Detailed Description

This StrongArm trunk lid lift support is engineered for direct replacement on a defined group of classic GM cars, including 1979-1985 Buick Century, 1979-1985 Buick LeSabre, 1979-1985 Oldsmobile 98, 1979-1985 Oldsmobile Delta 88, 1982-1984 Buick Regal, 1980-1983 Chevrolet Caprice, and 1979-1983 Chevrolet Impala. It also covers additional applications such as 1979-1981 Pontiac Bonneville, 1979-1981 Pontiac Catalina, 1983 Pontiac Parisienne, 1979 and 1982 Chevrolet Malibu, 1980-1981 Oldsmobile Cutlass except Ciera, and 1979-1980 Oldsmobile Cutlass Salon except Ciera. The StrongArm 4002 part number appears in interchange listings for related OE and aftermarket references, making it easier to match the correct trunk support for your vehicle.

What It Helps Fix

  • Trunk lid that drops too quickly when opened
  • Weak or failed lift support that no longer holds the lid up
  • Uneven or inconsistent trunk opening effort
  • Noise or binding caused by worn internal support components
  • Reduced stability when accessing the trunk compartment

Installation Notes and Tips

Verify the end style, compressed length, extended length, and stroke length before installation to confirm the correct application. This part uses blade-with-retainer ends with a .312 in. hole at both ends, so the mounting points must match the vehicle’s original hardware. For reliable trunk lid support and balanced operation, replace lift supports in pairs when the vehicle uses two supports.

Quality Assurance

StrongArm manufactures lift supports beyond industry standards and custom engineers each unit for smoother operation and longer service life. The 4002 is built as a specific-fit replacement for the listed Buick, Oldsmobile, Chevrolet, and Pontiac applications.
