Front Upper Control Arm with Ball Joint Set for 2006-2011 Lexus GS

Our review of the Front Upper Control Arm with Ball Joint Set finds it best suited for owners of 2006-2011 Lexus GS models who need a straightforward, vehicle-specific suspension replacement. The 2-piece kit includes both the driver and passenger front upper control arms with preinstalled ball joints, making it a convenient OE replacement. Fitment is the single biggest reason to consider this kit: it is sold as a direct fit, with OE reference numbers listed to help ensure compatibility with GS300, GS350, GS430, GS450h and GS460 applications.

Key Features

• Direct Fit: Designed to match factory mounting points so installation is typically faster and requires fewer modifications than generic aftermarket arms.
• Complete Kit: Includes both front driver and passenger upper control arms with ball joints, so both sides can be serviced at once for consistent suspension geometry.
• OE Reference Numbers: Ships with OE reference numbers to help buyers verify compatibility and reduce the chance of ordering the wrong part.
• Aftermarket Cross References: Multiple aftermarket reference numbers are provided so installers can confirm equivalence with other replacement part listings.
• Vehicle Specific Fitment: The listing emphasizes checking fitment for specific model years and drive configurations to ensure proper match for rear wheel drive Lexus GS models.

Who It's For

This kit is targeted at Lexus GS owners (2006 GS300, 2007-2011 GS350, 2006-07 GS430, 2007-11 GS450h, 2008-11 GS460) who want an OE-style, vehicle-specific replacement for worn upper control arms and ball joints. It suits DIY mechanics and independent shops that prefer swapping both sides with a matched set to maintain alignment and handling.

Those who should look elsewhere include owners of non-listed vehicles or buyers seeking heavy-duty, performance or adjustable aftermarket control arms; this kit is a direct OE replacement rather than a performance upgrade.
