Replacement Tesla Model 3 / Model Y rear upper fore link assembly (stamped steel control arm).
This arm sits in the upper-forward position of the rear multi-link suspension and helps locate the rear wheel laterally while working with the aft link to control camber and toe. Bent arms or worn bushings can cause rear-end instability, clunks, and irregular tire wear. This stamped arm is a direct-fit replacement for Tesla part number 1044427-00-C and is supplied under Gruber PN 34-TS3-RUPRFRLK.
Built by Suspensia, this control arm uses High Strength Low-Alloy (HSLA) steel for maximum safety and durability. Each arm is developed and verified as an exact fit for its application, manufactured using advanced robotic welding and assembly to meet or exceed OEM performance. A corrosion-resistant finish helps the arm stand up to harsh weather and road conditions, and thorough testing is backed by Suspensia’s non-transferable warranty.

| Compatibility notes | Tesla has used multiple rear suspension arm revisions on Model 3 / Model Y. Always match the part number stamped on your original rear upper fore link (1044427-00-C) and verify fitment by VIN and build date. Rear suspension arms (fore vs. aft, upper vs. lower) are not interchangeable. Contact us if you need help confirming compatibility before ordering. |
Whenever a rear suspension control arm is replaced, a four-wheel alignment is highly recommended to restore proper camber and toe and protect your rear tires from premature wear. After installation, road test over various speeds and surfaces to confirm the vehicle tracks straight and that any previous rear-end noise or instability has been resolved. Inspect the matching rear upper aft link, lower arms, and bushings at the same time to address other potential wear items.
Not sure if your Model 3 or Model Y uses this exact rear upper fore link? Check the part number on the original arm or provide your VIN, model year, and build date. We can help confirm that this 1044427-00-C / 34-TS3-RUPRFRLK assembly is the correct match for your vehicle before you order.
