TRQ Front Upper and Lower Control Arm with Ball Joint Set - Direct Fit

In this review the TRQ Front Upper and Lower Control Arm with Ball Joint Set is evaluated for do-it-yourself mechanics and independent shops needing a direct fit replacement for certain Infiniti sedans. The bottom line: this 4 piece control arm kit is best for owners seeking a ready-to-install option that replaces both upper and lower front arms on compatible rear-wheel-drive models, because the units arrive pre-assembled with ball joints to reduce installation time and avoid modification. The review focuses on fit, build quality, and real-world ease of installation.

Key Features

• Complete kit: Includes two front lower and two front upper control arms with ball joints so both sides of the front suspension are replaced at once for consistent handling.
• Direct fit design: Pre-assembled components are intended as replacement for the original equipment, which simplifies installation and avoids the need for custom modifications.
• Compatibility guidance: Fits specified 2007-2015 Infiniti G25/G35/G37 and Q40 rear-wheel-drive models, making it appropriate for multiple model years without guesswork.
• Reference mapping: Supplied reference numbers help confirm part-for-part compatibility with existing components during ordering and fit checks.
• DIY support: The brand provides DIY video resources aimed at helping users "view before they do" and follow correct installation steps.

Who It's For

This set is aimed at owners of compatible Infiniti models who want a straightforward replacement for worn control arms and ball joints, and for independent shops that prefer to swap all four front links in one service to restore steering geometry. The pre-assembled joints and complete kit make it practical for competent DIYers who have basic suspension tools and alignment access.

It is not for owners who drive non-compatible variants or all-wheel-drive versions, or for those who require OE-branded parts with manufacturer warranties; verify fitment carefully against the vehicle's parts references before buying.

Pros & Cons
