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!

All gains measured at the rear wheels.

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!
