Description

Industrial Injection XR1-series modified stock-frame turbocharger for 2001-2004 Chevrolet Silverado 2500HD/3500 and GMC Sierra 2500HD/3500 6.6L LB7 Duramax. Built on the factory LB7 IHI housing with a 63.5mm Billet Blade Technology compressor wheel and a polished compressor housing — the larger-wheel sibling to the XR 61mm.

The billet wheel and slim-nose design are engineered to improve compressor efficiency over the OE cast wheel, with the goal of lower EGTs and added strength under sustained load.
