Front Lower Control Arm with Ball Joint Set for Lexus RX350 RX450h

In this review the focus is on the TRQ style 4 piece front lower control arm with ball joint set designed for Lexus RX and compatible Toyota models. The bottom line: this kit is for a DIYer or independent shop that needs a direct fit, OE replacement-style control arm and ball joint assembly that matches original locations and mounting points. Our review finds the set delivers straightforward fitment across the listed years and models, offers a clear value proposition compared with purchasing individual parts, and is especially useful when replacing both sides at once to restore front suspension geometry.

Key Features

• Direct Fit: Installs without modification on compatible model years to save time and maintain factory alignment points.
• Complete 4 Piece Kit: Includes two front lower control arms and two matching front lower ball joints so both driver and passenger sides are replaced simultaneously.
• OE Replacement Style: Built to the same mounting layout as original equipment to preserve handling and steering response when properly installed.
• Vehicle Specific Fitment: Fitment covers a broad set of Lexus RX350/RX450h and Toyota Highlander and Venza years; checking the listing for exact compatibility prevents ordering the wrong set.
• Aftermarket Reference Numbers: Multiple cross reference numbers are provided to help confirm compatibility with repair manuals and parts catalogs.

Who It's For

This set is aimed at owners of 2008-2022 Lexus RX350, RX450h and related Toyota Highlander and Venza models who want a full front lower control arm and ball joint replacement without mixing brands. It suits home mechanics comfortable with suspension work and independent shops that prefer replacing both sides together to ensure balanced wear and alignment.

It is not the best choice for vehicles outside the listed fitment or for customers who require premium corrosion-resistant coatings or extended-life ball joints; those buyers should consider OE dealer parts or high-end aftermarket assemblies with proven long-term corrosion performance.

Pros & Cons

Pros

• Complete kit replaces both lower arms and ball joints so suspension geometry can be restored evenly.
• Direct fit, OE-style components simplify installation and reduce the need for additional modifications.
• Good value for money compared with buying components separately, especially for multi-year fitment coverage.
• Multiple aftermarket reference numbers make cross-referencing easier for technicians.

Cons

• Ball joint longevity and rust resistance have mixed customer feedback, so long-term durability may vary by environment.
• Not intended for vehicles with air suspension variants unless the listing specifically confirms that configuration.
