TRQ Front Control Arm with Ball Joint Set Compatible with 2009-2015

In this review of the TRQ Front Control Arm with Ball Joint Set, the bottom line is straightforward: this four-piece, direct-fit kit is for Lexus IS250 and IS350 owners who need a complete front suspension overhaul without sourcing individual arms and joints. The kit replaces both front lower control arms and both front upper control arms with ball joints, offering an OE replacement fit that simplifies repair. For anyone who values a direct-fit OE reference and straightforward installation, this set delivers the one thing most buyers want most: reliable compatibility and ready-to-install components.

Key Features

• Direct Fit: The kit is designed as an OE replacement for a bolt-in fit that saves time during installation and minimizes alignment surprises.
• Complete 4-Piece Set: Includes two front lower control arms and two front upper control arms with ball joints so both sides are refreshed at once for balanced handling.
• Vehicle Specific Fitment: Fitment information covers 2009-2015 IS250 and IS350 variants so installers can verify compatibility before purchase.
• OE Reference Matching: Supplied reference numbers align with common OE and aftermarket codes to help confirm correct replacement parts for the vehicle.
• Aftermarket Cross References: Multiple aftermarket and parts-house reference numbers make it easier to compare this kit with other suppliers and catalog entries.

Who It's For

This kit is best for DIY mechanics, independent shops, and Lexus owners who need a full front control arm replacement for 2009-2015 IS250 and IS350 models, including coupe variants listed in the fitment. It is especially useful when both upper and lower arms are worn or when replacing a failed ball joint, since the kit contains both arms and the pressed-in ball joints for the uppers.

Drivers who need a single arm or who own a different make or model should look elsewhere; the kit is vehicle-specific and meant to replace both sides at once. Also consider OEM parts if retaining factory-branded components is a strict requirement.
