Aston Martin 8D33-5A771-AA Rear Anti Roll Bar, 29mm Sport Pack Upgrade

Increase rear roll control with the 8D33-5A771-AA rear anti roll bar, an approximately 29mm factory high-performance specification bar used across several Sport Pack and higher performance Aston Martin applications. Compared with the standard approximately 25.2mm rear bar, the 8D33 bar provides substantially greater roll stiffness, helping reduce body roll, sharpen transient response, and improve rear axle control during cornering.

This OEM based upgrade is an excellent choice for standard suspension vehicles being converted to a Sport Pack style suspension setup. When installed with the matching 6G33 front bar, it provides a more cohesive front to rear handling balance, allowing the chassis to respond more predictably during fast road and track driving.

Compatible with:

2006 to 2018 Aston Martin V8 Vantage, 2010 to 2018 V12 Vantage, 2007 to 2014 DBS, 2012 to 2013 Virage, 2012 to 2013 V12 Zagato, 2013 to 2016 DB9, and 2013 to 2018 Vanquish models, where the vehicle is equipped with the standard rear anti roll bar.
