The compressor features an anodized 11 bladed billet aluminum wheel that is lighter and stronger than the stock cast wheel to help provide quicker "spool-up" and higher air flow than the stock turbocharger. This turbocharger setup can be installed on 11-16 Chevrolet Silverado 2500HD/3500HD 6.6L (td), 11-16 GM Sierra 2500HD/3500HD 6.6L (td) as a direct bolt-on replacement. All connections to the vehicle are compatible with the OE geometry, resulting in a quick and reliable connection.
