Product Details
Restore factory handling while elevating steering precision and driver confidence with the 034Motorsport Density Line Control Arm Kit for Audi C8 models. Designed as a comprehensive solution for worn or aging suspension components, this kit replaces the factory upper and lower control arms, front sway bar end links, and ball joints with performance-engineered Density Line components that deliver sharper response and improved chassis stability without sacrificing comfort.
Factory C8 suspension bushings are designed with comfort as the primary objective, utilizing soft rubber compounds and fluid-filled lower control arm bushings that deteriorate over time and can leak under repeated load and heat cycles. 034Motorsport Density Line Control Arms eliminate these compromises with higher-durometer rubber bushings that provide more precise suspension articulation and improved steering feel while maintaining excellent street manners for daily-driven luxury and performance applications alike.
Whether you drive an Audi A6, Allroad, A7, S6, S7, RS6, or RS7, this complete front suspension refresh kit is engineered to restore tight, predictable handling and reduce unwanted front-end movement during spirited driving, highway cruising, or aggressive cornering.
The included Density Line Lower Control Arms feature durable 65-durometer rubber bushings and new ball joints to improve front-end stability and steering accuracy while eliminating the failure-prone fluid-filled factory bushings. Density Line Upper Control Arms utilize stiffer 70-durometer rubber bushings to further sharpen steering response and suspension consistency under load. Complementing the system are Density Line Front Sway Bar End Links, which reduce flex and improve sway bar effectiveness for more direct turn-in and improved handling feel.
Each component is engineered as a direct, drop-in replacement and includes the necessary installation hardware for straightforward installation and long-term reliability.
