High-Quality OEM Replacement Front Left Lower Control Arm

This front left lower control arm is compatible with the following Tesla models:

• Tesla Model 3 (2017–2023) – All trim levels and all powertrains (RWD, Dual Motor AWD, Performance)
• Tesla Model Y (2020–2023) – All trim levels and all powertrains (RWD, Dual Motor AWD, Performance)

The compatibility chart is provided as a general reference. To confirm 100% exact fitment, please match the OE Part Number on your original component or contact us with your vehicle's VIN before purchasing.

This listing includes:

• 1x Front Left Lower Control Arm – Main Body (Driver Side)
• Pre-installed Inner Rubber Bushings
• Pre-installed Outer Ball Joint

This is a single left-side (driver side) arm. If you also require the right-side (passenger side) arm, please check our store for the corresponding listing. Installation instructions are not included with this product.

This arm arrives with pre-installed inner rubber bushings and an outer ball joint for several key reasons:

• Faster Installation: No need to press or install separate components — the arm is ready to fit straight from the box
• Correct Component Matching: The bushings and ball joint are matched and tested specifically for this arm and these Tesla models
• Reduced Risk: Eliminates the risk of incorrect bushing or ball joint fitment during installation, which could compromise suspension geometry
• Convenience: Reduces the number of separate parts a technician needs to source and handle during the repair

High-grade aluminum is the preferred material for Tesla and premium EV suspension components for several important reasons:

• Weight Reduction: EVs are inherently heavier than equivalent ICE vehicles due to battery packs. Aluminum control arms reduce unsprung weight, improving suspension responsiveness and ride quality
• Strength-to-Weight Ratio: Aluminum delivers excellent structural strength without the penalty of steel's added mass
• Corrosion Resistance: Aluminum naturally resists rust and corrosion, extending the service life of the component
• OEM Match: Tesla uses aluminum control arms on the Model 3 and Model Y as factory-fitted components — this replacement matches that specification directly
• Handling Improvement: Lower unsprung weight means better tyre contact, sharper steering response, and improved overall handling dynamics

Professional installation by a qualified technician is strongly recommended. Replacing a front lower control arm on a Tesla requires:

• EV-safe lifting equipment and specialist suspension tools
• Correct torque specifications for all fasteners to maintain safe suspension geometry
• Knowledge of Tesla Model 3 and Model Y suspension system specifics
• A four-wheel alignment performed immediately following installation

Incorrect installation can compromise vehicle safety, accelerate tyre wear, and affect the performance of Tesla's Autopilot, traction control, and regenerative braking systems. Note: Installation instructions are not included, and professional installation is required to activate the 10-Year Extended Warranty.

Yes — a professional four-wheel alignment is essential after replacing a front lower control arm on the Tesla Model 3 or Model Y. The front lower control arm directly influences camber, caster, and toe alignment angles.

For Tesla owners, correct alignment is especially important because:

• The increased kerb weight of EVs accelerates tyre wear significantly when alignment is even slightly off
• Incorrect geometry can reduce the efficiency and consistency of regenerative braking
• Proper alignment ensures Autopilot, lane-keeping, and stability systems operate as designed

Your technician should complete the four-wheel alignment immediately as part of the installation service.

Common signs of a worn or failing front lower control arm on a Tesla Model 3 or Model Y include:

• Clunking, knocking, or rattling sounds from the front-left suspension — particularly over bumps or during acceleration
• Vibration felt through the steering wheel, floor, or seat at speed
• Uneven, rapid, or inner-edge tyre wear on the front-left tyre
• Vehicle pulling or drifting to the left during driving or regenerative braking
• Vague, loose, or imprecise steering feel
• Repeated inability to achieve or hold a correct wheel alignment
• Visible cracking, tearing, or deterioration of the control arm bushings

Due to the Tesla's battery weight and instant torque, suspension components can experience accelerated wear compared to conventional ICE vehicles. Have your suspension inspected promptly if any of these symptoms are present.

Yes — this front left lower control arm is compatible with all powertrain variants of the Tesla Model 3 (2017–2023) and Tesla Model Y (2020–2023), including:

• Standard Range (RWD)
• Long Range (Dual Motor AWD)
• Performance (Dual Motor AWD)

However, we always recommend confirming fitment by matching the OE Part Number on your original component or providing your VIN, as minor production changes across the model year range can occasionally affect part compatibility.

We offer two warranty levels:

• 10-Year Extended Warranty: Activated when the product is installed by a fully qualified professional. You must submit a copy of your garage fitment invoice within 30 days of installation to activate this coverage.
• 1-Year Standard Warranty: Applies by default if no garage invoice is submitted within 30 days of purchase.

All warranty coverage applies to the product only and excludes labour costs, installation charges, or any additional expenses incurred.

This is a high-quality aftermarket replacement part engineered to meet or exceed Tesla's OEM (Original Equipment Manufacturer) specifications. It is 100% brand new and designed as a direct replacement for the factory front left lower control arm on the Tesla Model 3 and Model Y.

Manufactured from the same high-grade lightweight aluminum as Tesla's original components, it delivers the same fit, function, and suspension geometry as the factory part — with pre-installed hardware for a faster installation, at a more competitive price point than a Tesla genuine part.

To confirm 100% exact compatibility before purchasing, follow these steps:

• Check Model & Year: Confirm your vehicle is a Tesla Model 3 (2017–2023) or Tesla Model Y (2020–2023)
• Match OE Part Numbers: Compare the OE Part Numbers in our specifications (104435400A, 104435100C, 134435400A) against the number printed or stamped on your original control arm
• Confirm the Side: This is the Front Left (Driver Side) lower control arm — ensure you require the left side before ordering
• Send Us Your VIN: Provide your Vehicle Identification Number and our team will confirm exact fitment before you place your order

Verifying the part number on your original unit is the most reliable method to ensure correct fitment for your specific Tesla.
