Big Hoss® Bundle

Banks iQ upgradeBig Hoss Bundle is the ultimate engineered power system for Duramax sport applications.

Big Hoss is Banks' free-breathing intake and exhaust upgrades balanced with calibrated tuning PLUS the Techni-Cooler® Intercooler System. Forget "flash" power: now you've got head-snapping power (+130 hp and +244 lb-ft) with staying power! Big Hoss maximizes engine efficiency and constant-duty power and keeps exhaust gas temps in check. All gains measured at the rear wheels.

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 and drivetrain. 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.)

THE ULTIMATE DURAMAX PRODUCT SHOWCASE!

Radio programmers nationwide have endlessly copied KROQ's formats." Sounds a lot like Banks Power ... powerful, often copied ... so what better partnership could there be than KROQ and Banks Power teaming up to create the insane "Roq Rig." It's got just about everything we make for the Duramax, so if you've got one and you're looking to take it to the next level (of power and awesomeness) take a sec and check out what all went into making this dream truck a reality...

Duramax expertsWho 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.

Clean Diesel Power for a Duramax LMM

2012-09-25

Banks shows us the path to more power without choking the environment.

by Harley Camilleri

We have seen plenty of diesel engine power adders that make large power numbers and provide truck owners with the ability to easily destroy drivetrain parts. With black soot pumping from an open 5-inch sewer pipe and a set of beefy tires up in smoke, the scene certainly lends itself to some manly entertainment. Unfortunately, that much available power usually causes an assortment or problems, including over fueling the engine and damaging the injectors, torching the turbo wth absurd EGTs, and breaking transmission internals incapable of handling the added stress of larger tires and nearly double factory power output. Towing becomes difficult too, since the torque becomes less linear as the tune ramps up towards redline. Add in the mandated emissions testing some states are adopting, and you have yourself a laundry list of unnecessary headaches. Click below to read the whole story and see how Banks Power avoids all of these problems—yet still delivers put-you-back-in-your seat power...

Duramax LMM Big Hoss Bundle reviewed by Truckin

2014-10-06

Last month we left you with our amped-up 2009 GMC LMM Duramax; proudly huffing on a blend of water-methanol thanks to the Gale Banks Engineering Double-Shot Injection system (check that story out here). On the rollers, our LMM Duramax picked up 100 hp and 121 lb-ft to the rear tires over stock. To say we were impressed with the performance of the 6.6L Duramax with the addition of the Water-Methanol Injection system would be a complete understatement. Everyday driveability remained exactly the same as stock. However, stomp the pedal to build some boost and the Water-Methanol Injection system really lit the fires -- easily frying the tires with a rolling burnout. Of course, as with any build, we were far from done in the power department -- we were after more.

This time we were back at the Gale Banks Engineering facility in Azusa, California, to take full advantage of the Water-Methanol Injection system by increasing airflow and fuel demand overall. Banks recommended their CARB-approved Big Hoss Bundle, which consisted of a Six-Gun Diesel Tuner with iQ 2.0 Man-Machine interface, Technicooler Intercooler system, Ram-Air Intake system, and Monster Dual 4-inch exhaust with matching black tips.
