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

In this review of the Front Right Upper Control Arm with Ball Joint, the bottom line is simple: it is a straightforward OE replacement for owners of compatible Infiniti sedans who need a direct-fit, budget-friendly suspension arm. The reviewer found it most useful for repairing a worn or damaged passenger-side upper control arm because it mirrors the original equipment reference numbers and mounts, so it reduces fitment guesswork. This review focuses on compatibility, build, and real-world fit so buyers can decide if this assembly meets their repair needs.

Key Features

• Direct Fit: Installs without modification on specified Infiniti models, saving time during replacement and reducing alignment surprises.
• OE Replacement Assembly: Arrives as a matched control arm and ball joint assembly so the critical suspension geometry is preserved for predictable handling.
• Aluminum Construction: Uses an aluminum control arm body to reduce weight while maintaining the stiffness needed for proper steering response.
• Vehicle Specific Fitment: Clearly lists fitment for 2007-2015 Infiniti G35, G37, G25 and Q40 models so buyers can check compatibility before ordering.
• Reference Numbers Included: Provides multiple OE and aftermarket reference numbers to help cross-check parts during installation or service.

Who It's For

This control arm is aimed at DIY mechanics and professional technicians replacing a failed passenger-side front upper control arm on compatible Infiniti sedans. It is particularly appealing to buyers who want a direct-fit, OE-style assembly that matches original mounting points and reference numbers for a predictable repair.

It is not the best choice for owners who need a performance upgrade, adjustable geometry, or a greaseable ball joint; those users should seek performance or rebuildable suspension components instead.
