Detailed Description

The Suspensia X21CJ1363 suspension control arm and ball joint assembly is built for the front left upper suspension location on compatible Jaguar platforms. It is a practical OE-style replacement for 2004-2009 Jaguar XJ8, 2004-2009 Jaguar XJR, 2004-2009 Jaguar Vanden Plas, and 2005-2009 Jaguar Super V8 models. This part number, X21CJ1363, uses forged aluminum for strength and reduced unsprung weight, while the included rubber bushings and dust boot support quiet operation and joint protection. Suspensia manufactures chassis parts in a fully automated OE facility and supplies OE or better quality components for the North American aftermarket.

This part cross-references MOOG Chassis Products RK621665 and Mevotech Supreme CMS40120 for the same application.

What This Part Helps Address

• Front-end looseness or wandering at the left upper suspension point
• Clunking or knocking from worn control arm bushings
• Uneven tire wear related to suspension geometry wear
• Ball joint play in the front left upper assembly
• Handling instability on Jaguar XJ8, XJR, Vanden Plas, and Super V8 models
