Side-specific lower suspension arm
Match the lower curved arm by side and reference number
This listing separates the right- and left-side lower curved arms used in the listed Model 3 and Model Y applications. Their shape, bushing orientation and reference numbers differ, so choosing by vehicle name alone is not enough.
Important: the main image shows both sides for comparison. The product selector lists one side at a time; a left/right pair is not stated as included.
What makes this a part-number purchase
Right and left are different
Right-side 1044359-00-A and left-side 1044354-00-A are separate selector options, not interchangeable names for the same item.
Mounting geometry must match
The curved body, large rubber bushing and joint end must align with the vehicle's existing lower-arm position.
Visible L/R markings help
Product images show side markings that can be compared with the delivered part before installation begins.
Diagnosis still comes first
Noise, looseness or tire wear can have several causes. A technician should identify the failed component instead of replacing the arm by symptom alone.
Select the confirmed side above
Right side: R 1044359-00-A
Choose this option only after the installer confirms the right-side reference number on the vehicle or removed component.
Left side: L 1044354-00-A
Choose this option only after the installer confirms the left-side reference number on the vehicle or removed component.
Three checks before payment
Confirm the failed part
A similar symptom does not prove this lower arm is the source. Use a physical suspension inspection.
Match the number and side
Compare the removed component or service data with 1044359-00-A for R or 1044354-00-A for L.
Check VIN and build configuration
The listed year range is a search guide; VIN/build configuration and any part-number supersession take priority.
Product and fitment details
Professional installation protects the repair
Do not install by appearance
The old and new components should be compared for side, curvature, mounting points and markings before any fastener is tightened.
Use current service data
Torque values and procedures are not provided on this page. The technician should follow current vehicle-specific repair information.
Finish with a full check
After suspension work, the technician should inspect adjacent joints and fasteners, then evaluate alignment and steering condition.
Brand and origin transparency
The current product images show CTR branding and manufacturing/reference markings. They do not document Tesla-branded retail packaging or a manufacturer certificate. The reference numbers support part identification, but they are not proof of genuine Tesla manufacture. Contact TESStudio before ordering if brand origin or documentation is required.
Related Model 3 and Model Y repair parts
These are separate service items and are not automatically required with this lower arm. Order them only when the vehicle inspection identifies a need.
Lower curved control arm FAQ
Does the order include both arms shown in the main image?
The image shows both sides for comparison, but the selector lists one right or one left arm. A pair is not stated as included.
Which number is for the right and left side?
The live options are R 1044359-00-A and L 1044354-00-A. Have the installer confirm the side convention and old part number before ordering.
Will it fit every Tesla Model 3 or Model Y?
No universal fit is claimed. The listing covers Model 3 2017-2023 and Model Y 2020-2024, subject to the vehicle's VIN/build configuration, old part number and any supersession data.
Is this documented as a genuine Tesla part?
The product media show CTR markings and do not show Tesla-branded packaging or a manufacturer certificate. Ask TESStudio for documentation if origin is a deciding factor.
Are the bushing and joint included?
The images show a bushing and joint assembled into each arm. The current listing does not separately itemize package contents, so inspect the delivered component before installation.
Should wheel alignment be checked after replacement?
The page does not prescribe a universal procedure. A qualified technician should assess alignment and steering condition after suspension work and perform what the specific repair requires.
Order only after the lower arm, side and part number are confirmed
A precise match and professional installation are the foundation of a trustworthy suspension repair.
