Tesla Model S Front Control Arm Kit, 6-Piece (2012–2021)

Description

Six complete front arms for Model S (2012–early 2021)

This is a front-only refresh: both steel upper arms, both forward lower (fore) arms, and both rearward lower (aft) arms. It is not an upper-arm-only kit, not an 8-piece hardware kit, and it does not fit 2021+ Plaid / new Model S, or Model X / 3 / Y.

What you are buying

• 6 complete arm assemblies with ball joints and bushings already pressed in
• Aftermarket parts built to the Tesla OE numbers below — not a Tesla Service Center boxed original unless the packing says so
• Bolts, alignment, rear arms, sway-bar links, and tie rods are not included. Photos show six arms only — we do not pack eccentric bolt 2007106 unless it is in the box you receive
• Most 2012–2021 Model S cars use air suspension. A lift and Tesla Jack Mode are expected. Shop time is typically half a day plus a 4-wheel alignment
• Uninstalled quality issues: 30-day exchange. Installed parts are not returnable for change of mind — see our warranty policy

What’s in the box

Match these numbers to the stamp on your arms. The two black arms are stamped-steel uppers. The four silver arms are the lower fore and aft links. Model X uses different uppers — do not order this kit for an X.

Qty	Part (plain name)	OE on this kit	Also fits if your stamp is
1	Front upper arm, left (steel)	1043965-00-A	1043965-00-B. RWD cars often show 6006532-00-A / B (same position)
1	Front upper arm, right (steel)	1043966-00-A	1043966-00-B. RWD cars often show 6008930-00-A / B
2	Front lower rearward / aft arm (same part left or right)	1027351-00-C	1027351-00-D / E or 1048951-00-A / B / C (later letter of the same aft arm)
1	Front lower forward / fore arm, left	1041570-00-B	1041570-00-A or 6007998-00-C. Not 1420341
1	Front lower forward / fore arm, right	1041575-00-B	1041575-00-A or 6006664-00-C. Not 1420346

Will this fit?

Look at the stamp on the arms. Year helps, stamp decides. Same OE worldwide for this generation — no US / EU / China split.

Install notes

Air suspension + tighten bushing bolts on the ground

Enable Jack Mode before you lift the car. If you torque the inner bushing bolts with the wheels hanging, the new rubber is pre-twisted and can tear early. Set ride height, then torque. Tesla uses a ride-height tool on the upper arm. Replace one-time lock nuts. Then a 4-wheel alignment. Camber on the aft arm is often set with eccentric bolt 2007106 from Tesla’s parts list — not included in this kit.

Joint	Typical Tesla spec	Note
Upper arm to knuckle	60 Nm	Replace the lock nut
Upper arm to body	68 Nm	From Tesla Model S service procedure; use the ride-height tool
Lower arms to knuckle / subframe	See current service manual	Value depends on the bolt. Always at ride height.

Most independent shops book half a day plus a 4-wheel alignment on air-suspension cars. A lift is expected. Torque figures above are from Tesla service information for 2012–2020 Model S — confirm on the manual for your VIN before you tighten anything.

Why replace the set

Clunks, wander, inner tire wear

Worn front bushings and ball joints let the wheel move under braking and over bumps. Refreshing left and right together keeps the geometry even.

No press required

These are complete arms. This kit is the no-press, full-arm route for a pre-Plaid Model S front end.

Need a different part?

Model X 6-piece kit Do not use this Model S set on an X. The upper arms are different. Model 3 6-piece kit 3 / Y use a different front geometry. Do not mix this S kit onto those cars.

FAQ

Is this only the upper arms? Is it 6 pieces or 8?

DetailsSix front arms: two steel uppers, two rearward (aft) lowers, two forward (fore) lowers. Not an 8-piece hardware kit. Eccentric bolts are not included. Not rear arms, not sway-bar links, not tie rods.

2021+ Plaid / new Model S?

DetailsNo. Plaid and the 2021+ new Model S use 1420321 / 1420326 uppers and a different lower set. Some early-2021 cars are still the old chassis — the stamp on the arm decides, not the calendar year alone.

Model X, 3, or Y?

DetailsNo. Model X shares some lower numbers (1027351 / 1041570 / 1041575) but uses different uppers (1027322 / 1027327) — buy the Model X kit. Model 3 and Y are a different platform.

My upper says 6006532 or 6008930, not 1043965 / 1043966.

DetailsThose are the usual RWD (single-motor) stamps for the same upper position this kit is built for. Order it. Do not order if the upper already says 1420321 / 1420326.

My aft arm says 1048951, not 1027351-00-C.

Details1048951 is a later letter of the same rearward arm family. Order this kit. If you see 1420-series lower numbers, send a photo first.

RWD vs Dual Motor / AWD? Air suspension?

DetailsYes for 2012–early 2021 Model S when the stamps match. Check the arm, not only the trim. Most of these cars have air suspension — Jack Mode, a lift, and a ride-height tool are expected.

Are these genuine Tesla-boxed parts?

DetailsThey are aftermarket assemblies made to the listed OE numbers. Uppers are stamped steel, matching this generation — not the later Plaid aluminum pieces. If you need a Tesla Service Center sealed original, say so before ordering.

Bolts and alignment? What about 2007106?

DetailsNot included. 2007106 is Tesla’s common eccentric bolt on the aft arm for camber. Replace one-time nuts from Tesla’s parts list. Alignment after install is required and billed by the shop.

How long does install take?

DetailsOn air-suspension Model S, most shops book half a day plus a 4-wheel alignment. A lift is expected. Torque the inner bushing bolts at ride height so the new rubber is not pre-twisted.

Warranty?

DetailsThis is a non-electronic part. Uninstalled quality issues can be exchanged within 30 days of delivery. Installed suspension parts are not returnable for change of mind. See our warranty policy.
