The factory front upper control arms are integral to the B8/B8.5 Audi A4/S4 & A5/S5/RS5 suspension. Still, they can start wearing out as early as 40,000 miles - especially on enthusiast-owned vehicles driven hard on the street or track. As the rubber bushings degrade and ball joints develop the play, alignment is compromised, and steering becomes less precise.

034Motorsport's complete Density Line Upper Control Arms are designed to be a performance replacement for all four factory front upper control arms. Featuring high-durometer rubber bushings and high-quality ball joints, Density Line Control Arms are engineered to limit unwanted deflection in the suspension, resulting in tighter handling, and a more precise steering response than even brand-new factory control arms can offer.
