Bankspower - Diesel Performance Specialists

Let it flow.

Banks Big Hoss Bundle replaces the power-robbing factory airflow inefficiencies (including the intercooler) with free-flowing components that dramatically increase intake airflow and air density and expel exhaust with virtually no backpressure.

Colossal power with staying power.

Banks balances the improved airflow with advanced CleanTune™ Technology that adds up to 43% more horsepower and torque than stock. This is tire-shredding, scenery-blurring constant-duty power that keeps its cool without adding black smoke. Big Hoss Bundle blasts you from 0-60 mph 20% quicker than stock.

The secret to longer life.

Forget mis-matched components. Run away from tuners that can destroy your engine. Everything in the Big Hoss Bundle is engineered to work together to maximize your engine's power, efficiency and durability. Big Hoss honors your vehicle by safely living within the limits of your engine. Your Duramax will run stronger and live longer!

Watch the featured video! This short segment from ESPN's Truck Stop gives an overview of the Big Hoss Bundle, as installed on professional snowboarder Tara Dakides' truck. (She's got an '03 Duramax, so there may be some variance between this system and the one made specifically for your truck.)

All gains measured at the rear wheels.

6.6L Duramax | 2006 Chevrolet Silverado 2500, 4 wheel drive, crew cab short bed, automatic, single rear wheel

*Note: Six-Gun & Speed-Loader/Banks iQ are recommended for off-road/racing use only. Banks' results as tested on highest level of Six-Gun with Banks iQ and recommended airflow improvements.

Who knows more about your Duramax than Banks? Banks designed and built the 6.6L Sidewinder S-10, which is the quickest and fastest ever diesel-powered drag racing pickup truck.  It holds the national quarter-mile record at 7.77 seconds at 180 mph! And it did it without the billowing black smoke common with improperly tuned diesels. Moral to the story? No one knows more about boosting Duramax performance safely and reliably than Banks.
