Density Line Upper Control Arm Kit

The 034 Motorsport Density Line Upper Control Arms are engineered as a performance upgrade to replace aging and worn front upper control arms on various Audi and Porsche vehicles. The factory front upper control arms, critical components of the suspension, can begin to wear out around 40,000 miles, especially in enthusiast-driven vehicles. As their rubber bushings degrade and ball joints develop play, the vehicle's alignment is compromised, leading to less precise steering. This construction limits unwanted deflection in the suspension system. This kit is a complete, drop-in replacement and includes front upper control arms (front left & right, rear left & right) along with a comprehensive installation hardware kit. The NVH (Noise, Vibration, Harshness) levels are rated as None to Low, meaning minimal NVH is transferred to the cabin. However, the manufacturer notes that NVH perception is subjective. Fitment is extensive, covering B8/B8.5 Audi A4, S4, RS4, A5, S5, RS5, Q5, SQ5, Allroad, as well as C7/C7.5 Audi A6, S6, RS6, A7, S7, RS7, and 95B Porsche Macan models across various years and engine configurations. The kit replaces factory part numbers 8K0407505A, 8K0407506A, 8K0407509A, and 8K0407510A.
