Front Right Upper Control Arm with Ball Joint for Lexus IS Models

In this review of the Front Right Upper Control Arm with Ball Joint, the bottom line is simple: this OE replacement is aimed at owners of 2006-2020 Lexus IS models who need a direct-fit, budget-friendly repair for a passenger-side front upper control arm. The reviewer found it to be a straightforward replacement that matches original geometry and reference numbers, making it a practical choice when the goal is restoring suspension alignment and handling without paying dealership prices. Fitment must be checked against vehicle years and submodels before purchase.

Key Features

• Direct Fit: Replaces the factory passenger-side front upper control arm with no major modification required, helping speed up installation and alignment.
• Integrated Ball Joint Assembly: Comes with the ball joint preassembled, so installers do not need to press in a separate ball joint during replacement.
• OE Reference Match: Built to match OE reference 4861059065 and several aftermarket numbers, which helps ensure compatibility with specified Lexus IS years.
• Steel Construction: Uses a steel control arm body designed to mirror original strength and mounting points for predictable handling.
• Bushings Included: Arrives with bushings installed, reducing parts sourcing and simplifying the swap-in process for technicians and experienced DIYers.
• Vehicle Specific Fitment: Listing includes detailed year and model compatibility so buyers can confirm fit before ordering.

Who It's For

This part is best for DIY mechanics, independent shops, and Lexus IS owners (2006-2020 range) who need a passenger-side front upper control arm that closely matches original equipment without OEM pricing. It suits vehicles listed in the fitment notes: IS250, IS300, IS350, IS200t and the IS F in the specified years.

It is not ideal for someone seeking a heavy-duty upgraded performance arm or an adjustable aftermarket suspension component; buyers wanting greaseable or adjustable arms should look at specialty performance parts instead.

Pros & Cons

Pros

• Direct-fit replacement that generally installs without modification and restores correct geometry.
• Preassembled ball joint and included bushings reduce installation steps and parts hunting.
• Matches OE reference numbers for confident compatibility checking with vehicle fitment.
• Offers good value compared with dealer-priced replacements while keeping original mounting design.

Cons

• Ball joint is non-greasable and some customers have reported ball joint issues, so long-term durability may vary by use and driving conditions.
• Not adjustable, so alignment corrections beyond standard replacement require separate adjustment at the alignment shop.

Frequently Asked Questions

Does this control arm fit my IS350?
Check the vehicle year against the listing; this part covers many IS350 model years in the 2006-2020 range but confirm fitment for your exact year and drivetrain.

Is the ball joint serviceable or greaseable?
The ball joint is press-in and non-greasable, so it is not designed for routine greasing.

Are bushings included or do I need extra parts?
Bushings are included with the control arm, so separate bushing replacements are not required for the swap.
