Billet Aluminum Differential Bushing Insert Kit

The factory rear differential carrier bushings in these vehicles are known to have voids within their rubber damping material, which can result in noticeable drivetrain slop and undesirable clunking sounds during acceleration, deceleration, and gear shifts. By installing this kit, drivers can expect a more refined driving experience with smoother shifting and throttle transitions. Crucially, the design aims to maintain the vehicle's original ride quality without introducing new noises or vibrations, providing a noticeable improvement in drivetrain responsiveness. The inserts are constructed from durable billet aluminum, ensuring longevity and performance. This insert kit is compatible with a wide range of Audi models, including the B8/B8.5 A4/S4, A5/S5/RS5, Q5/SQ5, C7 A6/S6/RS6, and A7/S7/RS7. Fitment extends across various generations and model years within these lines, from the B8 Audi A4/S4 (2009-2012) up to the B9.5 Audi A4/S4 (2020-2024), and similarly for the other listed model families.
