• Hard-to-lift power liftgate operation
• Worn rear lift support causing inconsistent hatch movement

Installation Notes and Tips

Verify the vehicle is equipped with a power liftgate and confirm left-side placement before ordering. Compare the original support length, end fittings, and mounting points to the replacement part number 615050 before installation. Replace only the specified side unless inspection shows both supports require service.
