ACDelco 84663715 Driver Side Liftgate Window Strut Lift Support

The ACDelco 84663715 is an OE-replacement driver side liftgate window strut (lift support) designed and validated to General Motors factory specifications.

Key Features:

• Gas-filled design — provides consistent lifting force to support and hold the liftgate window glass open
• Steel outer cylinder with a black finish for corrosion resistance
• Nylon ball socket ends (both End 1 and End 2) for smooth articulation and secure mounting
• Compressed length: 11.57 in (294 mm)
• Cylinder outside diameter: 0.59 in (15 mm)
• Inner shaft diameter: 0.24 in (6 mm)
• Driver side (left rear) position — specific fit, not universal
