AUTOACER 2-Piece Rear Upper Control Arm Kit is designed as a replacement component set for compatible vehicles. These rear upper control arms are part of the rear suspension system and are used to support wheel alignment and control suspension movement during normal driving conditions. Worn or damaged control arms and ball joints may result in clunking noise, uneven tire wear, or reduced vehicle stability, and replacement can help restore proper suspension function. This kit is compatible with select models including 1999–2007 S-Type (X200), 2004–2009 XJ (X350/X358), 2014–2019 XJ (X351), 2006–2014 XK/XKR/XKR-S (X150), and 2008–2015 XF/XFR/XFR-S (X250). Fitment should be verified based on specific model and configuration. (Compatibility with other models such as XF X260 or F-TYPE should be confirmed before purchase.) The kit includes two rear upper control arms with pre-installed bushings and ball joints. These components are manufactured using steel, aluminum, and rubber materials designed to handle standard suspension loads and operating conditions. The control arms are designed as direct replacements corresponding to OE reference numbers including XR857871, C2P13876, C2C10438, XR822289, C2C33866, C2C21163, C2C39587, XR857872, C2P13877, C2C39588, C2C36987, and related part numbers which may be used for compatibility verification. Professional installation is recommended, as proper tools are required for suspension work. All fasteners should be tightened according to manufacturer torque specifications, and a wheel alignment should be performed after installation to ensure correct suspension geometry and tire wear. AUTOACER provides a 2-year manufacturer warranty covering manufacturing defects for this rear suspension component kit.
