Adjustable steel lower transverse control arms Nissan 350Z Z33 / Infiniti G35 V35 - Uniball [551B0-AL500]

PMC Motorsport Adjustable Steel Rear Lower Control Arms Nissan 350Z (Z33) / Infiniti G35 (V35) with Uniball Ends (Black) – Replacement for 551B0-AL500

A set of adjustable steel rear lower control arms for Nissan 350Z (Z33, Fairlady Z) and Infiniti G35 / Nissan Skyline (V35). The arms are fitted with Uniball spherical bearings and serve as a direct replacement for the factory rear lower control arm Nissan OE 551B0-AL500. The length adjustment range is 432–471 mm (17.01"–18.54"), allowing precise correction of the rear axle geometry after suspension lowering or wheel setup changes. The kit is designed for coilover suspension.

Key Benefits

• Precise rear axle geometry correction – smooth arm length adjustment allows you to dial in rear suspension alignment for lowered ride heights, wider wheels and tires, or specific applications: street, track, or drift.
• Rear-end stability under load – rigid control arms eliminate unwanted geometry deflection during hard acceleration, braking, and cornering, keeping the rear end predictable even under high horsepower.
• Even tire wear – properly dialed-in geometry limits premature and uneven tread wear across the rear tires.
• Direct handling without play – Uniball spherical joints eliminate factory rubber bushing deflection, delivering sharper and more immediate feedback to steering and throttle inputs.
• Durable steel construction – precision-welded control arms engineered specifically to withstand extreme loads in drifting, circuit racing, and time attack.
• Durable powder coating – RAL 9005 matte black powder coating protects the steel against corrosion and road salt.
• Made in Poland & quality tested – manufacturing and R&D are located in Poland, over 90% of components are produced in-house, each part is inspected after every production stage and engraved with an individual serial number. Quality certified according to PN-EN ISO 9001:2015.

Frequently Asked Questions

Which cars do these control arms fit?

They fit Nissan 350Z (Z33, Fairlady Z) Coupe and Roadster with VQ35DE and VQ35HR engines, as well as Infiniti G35 / Nissan Skyline (V35) Coupe and Sedan. The arms replace the factory Nissan OE 551B0-AL500 rear lower control arm.

Do these control arms fit the Infiniti G35 with Rear Active Steer?

No. G35 models equipped with Rear Active Steer (active rear-wheel steering) feature a different rear suspension design.

Do I need a coilover suspension?

Yes. The kit is designed specifically for coilover suspension systems.

What is the adjustment range?

The control arm length is adjustable within 432–471 mm (17.01"–18.54"), allowing you to dial in rear axle geometry for lowered suspension setups, wider wheels, or track settings.

Can I purchase individual components of the kit?

Yes. Each component of the set can be purchased separately – the PMC Motorsport team will help select the appropriate parts and provide technical support during installation.

Does installation require modifications?

No. The control arms mount directly to original factory points. A full suspension alignment on a professional rig is required after installation.

Is a Uniball bearing suitable for a daily driver?

Yes, although Uniball spherical joints transfer more vibrations to the chassis than soft factory rubber bushings. In return, they deliver precise and repeatable handling, making them ideal for performance street, track, and drift cars.

Does the price include customs duties for orders outside the European Union?

No. The product price and shipping quote do not include customs duties or import fees that may apply in the destination country.

Can I purchase with 0% VAT?

Yes, if you are a B2B customer outside Poland with an active EU VAT number (verified in VIES) or if ordering with shipping outside the EU.

PMC Motorsport parts are intended for motorsport use. Installation must be performed by a professional workshop, and a suspension alignment must be carried out after installing the control arms.
