6-Piece Front Control Arm Kit for Tesla Model S
Restore multiple major front-suspension links in one service with an OE-reference replacement set containing six control-arm assemblies plus two eccentric alignment bolts.
Complete Multi-Arm Refresh
Replaces six major front-suspension arm assemblies together for a more comprehensive service than changing only one isolated worn component.
OE-Reference Geometry
Individual arm positions correspond to Tesla OE references, allowing the replacement set to be checked against the vehicle's original suspension components before installation.
Alignment Hardware Included
Two eccentric lower-control-arm bolts are included for the corresponding suspension mounting positions and subsequent wheel-alignment adjustment.
Why Replace the Front Arms as a Complete Kit?
The kit includes separate Model S upper-control-arm assemblies for the left and right front suspension positions.
Two matching lower control-arm assemblies with current OE reference 1027351-00-C are included in the set.
OE references 1041570-00-B and 1041575-00-B complete the left/right lower lateral-arm portion of the kit.
Replacing worn or damaged arm assemblies with correctly matched components helps restore the intended relationship between the front wheel and chassis mounting points.
A professional alignment after suspension work allows the technician to check the resulting wheel geometry before returning the vehicle to normal road use.
“6-Piece” Means Six Control Arms
The current product title still says “6-Piece,” but the complete package includes six control-arm assemblies plus two eccentric bolts. That means the current listed package contains eight physical items.
Complete Kit Contents
The current source table displays “Lower Control Arm 104895100A” next to OE 1027351-00-C, but it does not explain whether 104895100A is an earlier number, alternate reference or cross-reference. This page therefore uses 1027351-00-C as the primary verified OE number.
Verify VIN & OE Numbers Before Installation
The current Tesery and TESKAY listings state Tesla Model S — all variants. Because suspension components can be revised across production years, confirm your VIN and required OE references before ordering.
Inspect control arms, bushings, joints, steering parts, wheels and tires to identify the actual source of noise, looseness or abnormal tire wear.
Compare the original suspension components and VIN-specific parts information with the OE numbers shown on this page before disassembly.
Verify arm shape, mounting locations, bushing positions and joint orientation before fitting each replacement assembly.
Use current vehicle-specific service data for removal, installation, suspension loading position and fastener tightening. Generic torque values should not be substituted.
Fit the supplied eccentric bolts in the corresponding lower-control-arm mounting locations according to the correct Model S service procedure.
Complete a full wheel alignment after installation and verify suspension geometry, steering behavior and tire tracking before normal road use.
These are structural suspension components. Installation should be performed by a qualified technician using appropriate lifting equipment, suspension tools and current Model S service procedures.

Quick Answers
Is this a 6-piece or 8-piece kit? +
It contains six control-arm assemblies plus two eccentric bolts. The “6-piece” name refers to the six suspension arms, while the current complete package lists eight physical items.
Which Tesla does this kit fit? +
The current manufacturer and TESKAY listings describe it as compatible with Tesla Model S all variants. VIN and OE-number verification is still recommended before ordering suspension parts.
Does it definitely fit a 2021+ Model S Refresh? +
The current listing says “all variants,” but it does not publish a separate Refresh-specific OE table. For newer vehicles, confirm the VIN and required OE references before ordering.
What are the six control-arm OE numbers? +
1043966-00-A, 1043965-00-A, two pieces of 1027351-00-C, 1041570-00-B and 1041575-00-B.
What is the 104895100A number shown in the source table? +
The current source displays 104895100A next to the 1027351-00-C lower control arm but does not explain the relationship between the two references. Confirm the required OE number using your VIN before ordering.
What are the two extra bolts? +
The kit includes two lower-control-arm eccentric bolts, OE reference 2007106, for the corresponding suspension mounting and alignment-adjustment positions.
Is this only an upper control arm kit? +
No. Only two of the six suspension arms are upper control arms. The remaining four are lower control-arm / lower lateral-arm assemblies.
Can worn control arms cause clunking or vibration? +
Worn control arms, bushings or joints can contribute to suspension noise, vibration, loose steering feel and abnormal tire wear. Similar symptoms can also come from other components, so diagnosis should be performed first.
Can I replace only one worn arm? +
A technician may determine that only certain components require replacement. This listing is sold as a complete multi-arm kit for customers performing a broader front-suspension service.
Is professional installation required? +
Yes. The current manufacturer instructions specify professional installation for this suspension kit.
Is wheel alignment required afterward? +
Yes. The manufacturer explicitly states that wheel alignment is mandatory after installation.
Are torque specifications included? +
No suspension-fastener torque values are published on the current product page. The installer should use current, VIN-appropriate Tesla service information.
How should I confirm fitment before ordering? +
Confirm the Model S VIN and production configuration, then compare the required suspension OE references with the numbers listed on this page before installation.
