NEW OEM Tesla Cybertruck Second Row Seat Back Lumbar Assembly 1819957-99-B

Restore the rear seat-back system with this NEW OEM Tesla Second Row Seat Back Lumbar Assembly, part number 1819957-99-B, shown in the Cybertruck 2nd Row Seat Back Hardware catalog. This component forms the lumbar-support component within the second-row seat back structure. A correctly matched lumbar assembly helps restore the designed support contour and its relationship with the surrounding backrest components. It is appropriate when the original lumbar component is deformed, broken, loose, uncomfortable, or damaged during seat-back repair. Using the exact OEM part number supports factory-style assembly and avoids substituting a component with an unverified specification. Confirm the part number, vehicle configuration, and related seat hardware in the Tesla parts catalog before ordering or installation.
