OE Numbers: 1551488-99-B,155148898B,1551489-00-B,155148899B,155148800C,1091560-00-B

Our OUSIMY dual left and right electric power liftgate trunk struts serve as bolt-on direct OEM replacement actuators, manufactured exclusively to fit Tesla Model 3 sedans built from 2021 through 2023 equipped with factory automatic power trunk lift systems.

Finished in uniform matte black with solid reinforced structural bodies, this two-piece set mounts to the rear trunk liftgate on both driver and passenger sides via standard bolt-on attachment points. Every strut undergoes full factory load and cycle testing to match original factory sizing, wiring interfaces and lift output for all 2021, 2022 and 2023 Model 3 configurations.

We upgraded internal hydraulic sealing layers and reinforced built-in motor assemblies to overcome common original part defects such as internal fluid leakage, motor burnout and structural fatigue after frequent opening cycles. Bolt-on mounting and factory-matched wiring connectors enable straightforward replacement without drilling, frame cutting or wire splicing during installation.

It resolves recurring trunk lift malfunctions caused by degraded OEM hardware: weak lifting force that lets the trunk drop abruptly, buzzing or rattling noise during auto open/close cycles, unresponsive automatic power activation and failed soft-close functionality, eliminating repeated costly service visits at Tesla service centers.

This replacement strut pair clears liftgate power and hydraulic fault codes detected by standard OBD diagnostic scanners triggered by faulty factory trunk actuators.

Free standard shipping applies to all orders; inventory stored in overseas US warehouses delivers fast order dispatch and short domestic transit delivery times across the United States.

Every OUSIMY power liftgate strut set includes a 3-year manufacturer limited warranty; bolt placement landmarks are molded onto each strut body to aid experienced DIY fitting, and our support team provides pre-order VIN verification plus post-sale return, exchange and dedicated technical guidance.
