Product Details
This StrongArm tailgate lift support is engineered for rear body applications where controlled lift and hold performance matter. The 4531 part number is listed for 1995-2005 Chevrolet Blazer with dropgate, 1995-2001 GMC Jimmy with dropgate, 2002-2005 GMC Jimmy, and Oldsmobile Bravada models in the confirmed fitment range. If you are replacing a worn Chevrolet Blazer tailgate lift support or a GMC Jimmy rear support, this part number provides a direct-fit service option.
StrongArm manufactures lift supports as pressurized cylinders built to operate smoothly and deliver consistent support in automotive rear hatch and tailgate use. The steel cylinder construction, nylon ball socket ends, and low-friction material selection support stable movement and secure attachment at the mounting points. Part number 4531 is also listed under AMS Automotive 4531 and other common interchange references.
Common Problems This Part Can Address
- Tailgate or dropgate that will not stay open
- Rear support that drops too quickly when opened
- Weak or inconsistent lift assistance
- Binding or rough tailgate movement
- Loss of controlled rear access operation on supported vehicles
Installation Notes
Verify the end fittings, compressed length, and extended length against the original support before installation. Confirm the vehicle uses the listed dropgate or rear support configuration, since fitment varies by model and year. Replace lift supports in pairs when the vehicle uses matched left and right supports so the rear opening operates evenly.
Quality Assurance
StrongArm states that each lift support is custom engineered and manufactured beyond industry standards for smoother operation and longer service life. This part is built for the confirmed applications listed above, including Chevrolet Blazer and GMC Jimmy rear lift support service.
