In this review of the Front Upper Control Arm with Ball Joint Set the bottom line is clear: this 2 piece kit is aimed at DIY mechanics and owners of compatible Lexus GS and IS models who need a direct replacement with pre-assembled components. The reviewer found the set useful because it replaces both left and right upper arms with ball joints included, saving time and ensuring matching wear and fit.

Who It's For

This kit is best for owners of compatible Lexus models including 2006 GS300, 2007-2011 GS350, 2006-2015 IS250 AWD, 2011-2022 IS350 AWD, 2016-2023 IS300 V6 3.5L, and 2016-17 IS300 who need both front upper control arms replaced.
