A-revision front upper control arm

Confirm the upper arm side before ordering the A-revision assembly

This silver U-shaped front upper control arm is offered in exact left and right references: 1188321-00-A for LH and 1188326-00-A for RH. Side, mounting details and vehicle configuration should all agree before it reaches the installation bay.

Before checkout: Some media show both left and right arms to explain their mirrored design. The live selector is side-specific, and a pair is not stated as included.

What gives this purchase a clearer fitment trail

Exact A-revision options

Both live variants include a complete part number, making the order easier to compare with the removed arm or current service record.

Visible side identification

The media show L/R markings, bushings, the joint end and mounting features for pre-installation comparison.

Official procedure context

Tesla service material identifies the 1188321/1188326 family within front upper control arm procedures for listed Model 3 and Model Y generations.

Match the exact A-revision option

Choose the confirmed side in the live selector. Do not swap LH and RH or assume another revision is equivalent.

LH 1188321-00-A

For the left-hand front upper control arm position only after the existing reference or current service data confirms 1188321-00-A.

RH 1188326-00-A

For the right-hand front upper control arm position only after the existing reference or current service data confirms 1188326-00-A.

What a well-matched upper arm supports

The intended side geometry

The correct LH or RH choice aligns the mirrored U-shape, bushings, joint and brackets with the diagnosed side.

A more controlled repair decision

Matching the exact A-revision reduces reliance on generic Model 3/Y fitment claims.

Better pre-installation verification

Visible markings and mounting details give the technician multiple points to compare before installation begins.

Set the repair up around the vehicle, not a generic diagram

Confirm configuration and revision

Use the VIN/build configuration, existing reference and current service information before ordering or disassembly.

Inspect the complete assembly

Compare the U-shaped body, bushings, joint, side mark and sensor-related bracket details with the original arm.

Complete the required checks

A trained technician should follow current ride-height, fastener and post-repair alignment procedures for the specific vehicle.

Part and origin transparency

The product media show CTP and reference/origin markings on the photographed silver assemblies. They do not show Tesla-branded retail packaging or a manufacturer certificate, so this page does not represent those markings as proof of genuine Tesla manufacture.

1188321 / 1188326 upper control arm FAQ

Which option is left and right?

Choose LH 1188321-00-A for the left side or RH 1188326-00-A for the right side after confirmation.

Does one order include both upper arms?

A pair is not stated. The live selector is side-specific.

Can I replace another revision with this A revision?

Do not assume interchangeability. Confirm a documented supersession or exact service match for the vehicle.

Which Model 3 and Model Y years are listed?

The current product data lists Model 3 2017-2023 and Model Y 2020-2024, but exact build configuration and part number take priority.

What symptoms can an upper arm problem cause?

Upper-arm wear can be associated with noise, play or alignment-related concerns, but those symptoms are not unique to this part and require inspection.

Is alignment attention needed after replacement?

Tesla service information includes post-repair steering/alignment requirements for upper-control-arm work. A qualified technician should follow the procedure for the specific vehicle.

Confirm the component, side and full reference before checkout

A precise match and a professional repair plan protect both the installation and the decision behind it.
