Detailed Description

Mevotech Original Grade GS861137 is engineered as a premium OE replacement for the front right upper suspension position. It is built to match the original manufacturer’s fit, form, and function, helping restore handling consistency and ride comfort on Lexus IS250, IS350, IS200t, IS F, and IS300 models. The steel arm, rubber bushings, and pre-greased ball joint are selected for routine commuter use and regular road conditions. This part cross-references MOOG Chassis Products RK622661 for the same application.

Use GS861137 when replacing a worn upper control arm on a Lexus IS350 front right upper, or when servicing the front right upper suspension on a Lexus IS250 or IS F. The Mevotech GS861137 part number is also a useful reference when verifying OE-style replacement coverage for these Lexus chassis applications.

What It Helps Fix

• Clunking or knocking from the front suspension
• Loose or imprecise steering feel
• Uneven tire wear caused by worn suspension joints
• Excess play from deteriorated bushings or ball joint wear
• Ride quality changes from a fatigued upper control arm assembly

Installation Notes and Tips

Install on the front right upper suspension position only. Verify vehicle year, model, and trim before ordering, especially on Lexus IS250, IS350, IS200t, IS F, and IS300 applications. Because this assembly uses a press-in ball joint, proper service tools and alignment procedures are recommended after installation. The included hardware should be used where required during the repair.
