Front Lower Control Arm with Ball Joint Set for Audi A6 Quattro

In this review the reviewer tests the two-piece front lower control arm set designed for select Audi A6 Quattro, A8 Quattro and Volkswagen Passat models, and concludes it is a solid direct-replacement option for owners doing a suspension refresh. The bottom line: this kit is aimed at DIYers and independent shops who need a pair of pre-assembled lower control arms with ball joints that fit the specified model years and reference numbers, and it performs well for fit, basic durability and ease of installation.

Key Features

• Kit Content: Includes front driver side forward lower control arm with ball joint and front passenger side forward lower control arm with ball joint for a complete front pair replacement.
• Direct Fit Compatibility: Engineered to match original mounting points for the listed Audi and Volkswagen models so installers avoid modification and alignment surprises.
• Reference Coverage: Covers a wide set of reference numbers, making it easier to confirm correct replacement for older factory part listings.
• Pre-assembled Design: Delivered with ball joints installed to reduce bench work and speed up reassembly during a suspension job.
• DIY Support: Backed by the brand's extensive how-to video resources to help less-experienced installers perform the replacement correctly.

Who It's For

This set is best for owners of 2000-2004 Audi A6 Quattro, 2000-2003 A8 Quattro, 2001-2003 S8 and 2003-2005 Volkswagen Passat who need a direct-replacement front lower control arm pair with ball joints. It suits competent DIYers and independent repair shops who value pre-assembled parts and step-by-step video support to reduce install time.

It is not the best choice for vehicles outside the listed production date ranges or for users who need custom performance arms; those buyers should seek aftermarket performance control arms tailored for modified suspension geometry.
