034 Motorsport Australia - Audi B9 Q5/SQ5 Rear Differential Insert Mount Kit 034-505-2031
The 034 Motorsport Billet Aluminium Rear Differential Mount Insert Kit for the Audi B9/B9.5 Q5 and SQ5 is engineered to eliminate unwanted movement in the factory rear differential mounts. By filling the voids within the OEM rubber bushes, this kit stabilises the differential under load, maintains correct suspension geometry during cornering, and dramatically sharpens rear-end response.
This upgrade is ideal for enthusiasts looking to enhance traction, improve driveline precision, and enjoy a more connected and confidence-inspiring driving experience—without introducing any noticeable increase in cabin noise or vibration.
Product Description
The B9/B9.5 Q5 and SQ5 utilise soft rubber rear differential mounts that allow excessive movement under acceleration, deceleration, and hard cornering. This can create a vague rear-end feel, delayed throttle response, and inconsistent handling behaviour.
034 Motorsport’s Billet Aluminium Inserts are precision CNC-machined from T6-6061 aluminium to perfectly fill the factory voids and control differential motion without sacrificing refinement. These inserts work alongside the OEM rubber bushings and do not introduce additional NVH, making them ideal for daily-driven and performance-focused vehicles alike.
Tested extensively on 034Motorsport’s in-house B9 SQ5 Development Vehicle, this kit provides a noticeable improvement in driveline stability, reducing squirm under load and enhancing rear-end predictability during spirited driving.
Installation is simple, fully reversible, and requires no permanent modifications.
