Side-specific suspension replacement part
Replace the correct control arm, not just a similar-looking part
A control arm can look nearly identical from one side to the other, yet the mounting geometry and reference number are side-specific. This listing provides separate right- and left-side choices for the listed Model 3 and Model Y applications.
The safest buying decision: have a qualified technician match the number on the removed part and confirm the required side before ordering.
Why the exact match matters
Two distinct side references
The selector separates right-side 1044326-00-G from left-side 1044321-00-J so the order can follow the vehicle's actual repair requirement.
Assembled mounting points shown
Product images show the curved arm body with installed rubber bushings and a ball-joint stud for the selected side.
Visible side marking
The product media includes a close-up of the right-side marking, helping the installer compare the delivered part before fitting it.
Part-number fit comes first
Broad vehicle years are useful for searching, but the existing part number, VIN/build configuration and technician verification should decide the final fit.
Choose the side above before checkout
Right side: R 1044326-00-G
Select this only when the technician confirms the right-side reference number. Do not determine the side from the catalog photo alone.
Left side: L 1044321-00-J
Select this only when the technician confirms the left-side reference number. The listing does not state that both sides are supplied together.
Start with diagnosis, not symptoms alone
Clunks, looseness, uneven tire wear or a failed suspension inspection may lead a technician to examine the control arm, bushings or ball joint. Those symptoms can also come from other steering, wheel or suspension components.
Product and fitment details
Installation is part of the safety decision
Use a qualified technician
Control-arm replacement affects suspension attachment points and should not be treated as a cosmetic DIY installation.
Use current service data
Torque values and procedures are not published on this page. The installer should follow current vehicle-specific service information.
Inspect the full corner
Ask the technician to check adjacent bushings, joints, fasteners, tires and alignment condition instead of replacing parts by guesswork.
Origin and packaging transparency
The current product media show CTR markings on the component and do not document Tesla-branded retail packaging or a manufacturer certificate. The reference numbers help identify the application, but they should not be treated as proof of genuine Tesla manufacture. Contact TESStudio before ordering if brand origin or documentation is a purchase requirement.

These are separate maintenance items, not components automatically required for a control-arm replacement. Order only when the vehicle's diagnosis calls for them.
Tesla Model 3 and Model Y control arm FAQ
Does the order include both left and right control arms?
No pair is stated as included. The selector offers one right-side part or one left-side part; order the side confirmed by the repair diagnosis.
How do I choose between R and L?
Have the installer confirm the vehicle's side convention and match the removed part number. Do not rely only on the orientation of a catalog image.
Will it fit every Model 3 or Model Y?
No universal fit is claimed. The page lists Model 3 2017-2023 and Model Y 2020-2024, but the existing part number, VIN/build configuration and any supersession information should be checked first.
Is this documented as a genuine Tesla part?
The current images show CTR markings and do not show Tesla-branded packaging or a manufacturer certificate. Contact TESStudio for origin documentation if that distinction is required.
Are the bushings and ball joint included?
Product images show bushings and a ball-joint stud assembled into the arm. The existing listing does not separately itemize package contents, so inspect the delivered part before installation.
Will the vehicle need an alignment afterward?
The listing does not make a universal alignment claim. A qualified technician should evaluate alignment and steering condition after suspension work and perform any procedure required for the specific repair.
Confirm the diagnosis, side and part number before the repair begins
Correct identification and professional installation matter more than appearance alone on a suspension replacement part.
