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.

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.)

All gains measured at the rear wheels.

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.
