Adjustable steel upper longitudinal control arms Toyota Supra MKV - Uniball (black) [48770-WAA01] [48770-WAA02]

PMC Motorsport adjustable steel rear upper trailing arms Toyota GR Supra MKV (A90 / A91) with Uniball rod end (black) – replacement for 48770-WAA01 / 48770-WAA02

Set of adjustable steel rear upper trailing arms for the Toyota GR Supra MKV (A90 / A91). The arms are fitted with an M16x1.5 Uniball spherical rod end with steel bushings and serve as a direct replacement for factory control arms Toyota OE 48770-WAA01 (left) and 48770-WAA02 (right). The length adjustment range is 224–250 mm (8.82"–9.84"), allowing for precise rear axle geometry correction after lowering the vehicle or changing wheels.

Benefits for You

• Precise rear axle geometry correction – smooth length adjustment allows restoring or fine-tuning the rear suspension setup for lowered vehicles, wider wheels/tires, or specific applications: road, track, or drift.
• Rear-end stability under load – a rigid control arm prevents unwanted dynamic geometry changes during acceleration, braking, and hard cornering, ensuring predictable rear-end behavior even with high power output.
• Even tire wear – accurately set geometry prevents premature and uneven rear tire tread wear.
• Direct handling response – the Uniball spherical bearing eliminates the deflection of factory rubber bushings, providing faster and sharper reactions to steering and throttle inputs.
• Heavy-duty steel construction – designed to withstand extreme lateral and longitudinal loads in drifting, circuit racing, and time attack.
• Plug & play installation – direct replacement for OE arms 48770-WAA01 and 48770-WAA02, mounting directly to factory chassis points without any body modifications.
• Manufactured in Poland with strict quality control – every component is CNC-machined and inspected prior to dispatch.

Frequently Asked Questions

Which vehicle do these control arms fit?

They fit the fifth-generation Toyota GR Supra (MKV, A90 / A91, chassis designation DB) with 2.0 Turbo B48 and 3.0 Turbo B58 engines, including the A90 Edition. The arms replace the factory rear upper trailing arms Toyota OE 48770-WAA01 (left) and 48770-WAA02 (right).

What is the adjustment range?

The length can be adjusted within the range of 224–250 mm (8.82"–9.84"), meaning from 14 mm shorter to 12 mm longer than the factory arm (238 mm / 9.37").

Does the kit include both left and right arms?

Yes. The kit includes 2 adjustable control arms, which replace the factory left (48770-WAA01) and right (48770-WAA02) arms.

Does installation require any vehicle modifications?

No. The arms mount directly to factory chassis mounting points. After installation, a professional suspension alignment on a proper alignment rack is mandatory.

Is a Uniball bearing suitable for daily driving?

Yes, although a Uniball spherical bearing transmits more NVH and vibrations to the chassis than compliant factory rubber bushings. In return, it delivers precise and repeatable handling, making it ideal for performance street, track, and drift vehicles.

Does the price include customs duty for shipments outside the European Union?

No. The product price and shipping quote do not include customs duties, taxes, or import fees that may apply in the recipient's country.

Can I purchase with 0% VAT?

Yes, provided you are a B2B customer outside Poland with a valid EU VAT number (verified in the VIES system) or if the order is shipped as an export outside the EU.

PMC Motorsport components are designed for motorsport use. Installation should be performed by a professional workshop, and suspension alignment must be carried out immediately following installation.
