TRQ Front Right Upper Forward Control Arm with Ball Joint - Direct Fit

In this review of the TRQ Front Right Upper Forward Control Arm with Ball Joint, the bottom line is simple: this part is for owners of compatible Lexus LS models who want a direct-fit replacement that matches original dimensions and saves on dealer costs. The reviewer highlights that the component is pre-assembled, made from aluminum, and designed for the passenger side front upper forward location, making it a straightforward swap for 2007-2017 LS460 and 2008-2016 LS600h models. Installation ease and compatibility are the single biggest reasons to consider this part.

Key Features

• Direct Fit Compatibility: Engineered to replace the factory front passenger side upper forward control arm on specified Lexus LS models, reducing the need for modifications.
• Pre-assembled Design: The unit comes with bushings included and a pre-installed ball joint mounting for faster installation and less assembly time.
• Aluminum Construction: The aluminum arm offers a balance of strength and reduced weight compared with heavier steel alternatives, which helps maintain handling characteristics.
• Multiple Reference Numbers: Supplied with a long list of reference numbers for cross-compatibility checks so shoppers can confirm fitment against their part catalog entries.
• DIY Support: Backed by TRQ's DIY video resources to help confirm fit and guide the removal and installation process.

Who It's For

This control arm is best for DIY mechanics and independent shops working on 2007-2017 Lexus LS460 or 2008-2016 LS600h passenger side front upper forward suspension. It suits owners who prefer a direct replacement that matches original geometry and includes bushings to speed up the job.

It is less appropriate for vehicles outside the listed fitment or for restorations requiring OEM-branded original parts. If you need an adjustable arm or a greasable ball joint, this unit is not adjustable and the ball joint is not greasable, so look for a part that specifically lists those features.

Pros & Cons
