Front Upper & Lower Control Arm Set for 2001-2005 Lexus IS300

In this review the focus is on a direct-fit suspension replacement for 2001-2005 Lexus IS300 owners who need a full front arm refresh. The reviewer found this 6-piece set delivers a complete front upper and lower solution with preassembled ball joints, making it a practical choice for DIY mechanics and independent shops. The single biggest reason to buy is straightforward: it replaces all four control arms and both upper ball joints in one purchase, saving time compared with sourcing parts individually while maintaining fitment for the specified Lexus models.

Key Features

• Complete 6-piece kit: Includes two front lower forward, two front lower rearward, and two front upper control arms with ball joints so both sides are addressed at once.
• Direct fit components: Preassembled parts are designed as replacement pieces to match factory geometry and reduce the need for modifications during installation.
• Reference compatibility: Multiple OE and aftermarket reference numbers are listed to help confirm fit for the Lexus IS300 and related interchange applications.
• DIY support: The brand emphasizes video guidance so installers can view procedures before they work, which helps reduce errors and save time.
• Durability focus: Built as replacement suspension parts intended to restore original handling and alignment characteristics for older IS300 examples.

Who It's For

This kit is best for owners of 2001-2005 Lexus IS300 who want a coordinated front suspension overhaul without hunting multiple part numbers. Independent mechanics and experienced DIYers who prefer replacing all front upper and lower arms and ball joints at once will value the convenience and confirmed fitment.

Those who should look elsewhere include drivers seeking performance-oriented aftermarket geometry changes or parts for non-IS300 vehicles; compatibility is specific and buyers should confirm fit with the full reference list before purchasing.
