Front Left Upper Control Arm with Ball Joint for Infiniti G37 G35 G25

In this review of the Front Left Upper Control Arm with Ball Joint, the bottom line is simple: this direct-fit OE replacement is for owners who need a vehicle-specific, ready-to-install upper control arm assembly for Infiniti G37, G35, G25 and Q40 models. The reviewer found the assembly primarily valuable for its exact fit and straightforward swap with the original part, making it a practical choice when suspension geometry and alignment must be preserved without custom modification.

Key Features

• Direct Fit: The assembly is made to match factory dimensions so it installs without major modification and preserves steering geometry.
• OE Replacement: Built as an OE replacement unit to restore original handling and suspension function after wear or damage.
• Vehicle Specific Fitment: Clearly listed compatibility for Infiniti G37, G35, G25 and Q40 front driver side upper locations to reduce fitment guesswork.
• Aluminum Construction: The control arm material is aluminum, which reduces unsprung weight while retaining structural strength for long-term use.
• Integrated Ball Joint: Includes the ball joint as part of the assembly to simplify replacement and avoid separate matching of parts.
• Bushings Included: Comes with bushings installed so the unit is ready for direct replacement during a repair.

Who It's For

This part is aimed at DIY mechanics and repair shops working on Infiniti sedans from the specified years who want a one-piece replacement to restore front suspension function. It suits owners replacing worn or damaged driver side upper control arms who prefer a product that matches OE reference numbers for easier sourcing and alignment.

Those who should look elsewhere include drivers who need an adjustable performance arm or a greaseable ball joint; this assembly is non-adjustable and the ball joint mounting is machined with a non-greaseable joint. Also consider factory service or a different aftermarket option if you require an OEM-branded part beyond the listed references.
