034Motorsport Density Line Control Arm Kit - Audi B9/B9.5 A4/S4/RS4/A5/S5/RS5 - 034-401-1074

This Density Line kit replaces all eight factory front upper and lower control arms on B9 and B9.5 Audi A4, A4 allroad, S4, A5, S5 and RS5 models. 034Motorsport notes that factory arms can start wearing from around 40,000 miles, and as the bushings degrade and the ball joints develop play, alignment suffers and steering loses precision. The Density Line arms combine 65-70 durometer rubber bushings with quality ball joints to limit unwanted suspension deflection, which the brand says gives tighter handling and sharper steering than even new factory arms. The kit is a drop-in replacement and comes with new installation hardware.
