2006-2007 Duramax Towing Compound Turbo Kit (424403)

Industrial Injection's towing compound kit pairs a fast-spooling Silver Bullet PhatShaft high-pressure turbo with a BorgWarner S475 atmospheric secondary on the 2006-2007 6.6L LBZ Duramax, building boost early and lowering EGTs under heavy trailer loads. The kit is engineered for tow rigs and work trucks that need usable low-end power, strong airflow across the RPM range, and headroom for moderate tuning without giving up street manners.

Includes all piping, brackets, hardware, and oil/coolant lines required for installation on a stock-engine LBZ.
