Spherical Bearing Upgrade Kit for B5/B6/B7/C5 Audi A4/S4/RS4 & A6/S6/RS6 with Density Line Adjustable Upper Control Arms



This high-quality spherical bearing upgrade kit allows you to upgrade the inner bushings on your existing B5/B6/B7/C5 Audi A4/S4/RS4 & A6/S6/RS6 Density Line Adjustable Upper Control Arms with motorsport-grade Aurora spherical bearings.

This kit is designed to be pressed into our Density Line Adjustable Upper Control Arm Kit (034-401-1000), and features anodized billet aluminum bearing adapters and spacers, Aurora AU-PWB-12T spherical bearings, and internal circlips. Every kit comes as a set of four fully assembled adapters for installation into one complete set of upper adjustable control arms.

Replacing the Density Line rubber inner bushings with spherical bearings is ideal for racing applications where eliminating deflection is advantageous, as well as for extremely lowered vehicles that place excessive stress on the rubber bushings as the suspension articulates. This kit will maintain proper suspension geometry under extreme loads and allow for proper articulation without deflection to deliver precise handling and uncompromised performance.
