Stabilus 5B-314817 Liftgate Lift Support - Right

Liftgate Support for Tesla Model 3

This Stabilus Lift-O-Mat liftgate lift support is engineered for controlled rear hatch motion on the 2017-2023 Tesla Model 3, right side, with power liftgate. Part number 5B-314817 uses dynamic damping to deliver a smooth, measured opening and a gentle stop at the end of travel.

Key Features

• Fits 2017-2023 Tesla Model 3, right, w/ Power Liftgate
• Gas-charged lift support with ball socket ends
• Dynamic damping uses a velocity manifold for controlled extension
• Extended length: 13.58 in. (345 mm)
• Compressed length: 8.74 in. (222 mm)
• Stroke length: 4.84 in. (123 mm)
• Cylinder outside diameter: 0.866 in. (22 mm)
• Maximum force: 180 N (800 lbf)
• Nylon end materials for socket connection durability

Detailed Description

Stabilus 5B-314817 is a Lift-O-Mat liftgate support built for precise motion control on the Tesla Model 3 rear liftgate. The gas spring design uses a custom groove profile inside the tube to regulate gas flow as the hatch opens, helping the liftgate move with consistent resistance and settle softly at the end of the stroke. This OE-style damping approach is specified for applications that need refined control rather than abrupt movement. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Liftgate that drops too quickly when opened
• Rear hatch that no longer stays up reliably
• Uneven or jerky liftgate movement
• Weak gas strut performance on the right side
• Noise or harsh stop at the end of liftgate travel

Installation Notes and Tips

Verify the vehicle is a 2017-2023 Tesla Model 3 with power liftgate and confirm right-side placement before ordering. Ball socket ends should match the existing mounting points, and the liftgate should be supported safely during removal and installation. Compare the compressed length, extended length, and stroke length to the original support to confirm proper application. Part number 5B-314817 is also referenced as 314817, 574131, 991417, 1551489-00-B, and 155148900B.

Quality Assurance

Stabilus Lift-O-Mat supports are built for OE-level motion control and are used in applications where consistent damping and smooth liftgate operation are required. The dynamic damping design is engineered for controlled extension and a gentle closing stop.
