The Banks Power Pack works by reducing your throttle response time. The Banks Power Exhaust keeps your turbine blades running faster and increases maximum air flow. Thus, the engine is kept at a temperature in which it can work best, thereby increasing engine longevity and fuel efficiency. Air flow is important to the life span of your engine, and we want to give you that.Other performance-enhancing lines give you additional power at the expense of your engine, but the Banks Power Pack does not. Our experts at Gale Banks Engineering has carefully studied this for years, and our power kit is the fruit of that. The Banks Power Kit has undergone intense factory testing under real-world conditions just to make sure we come up with the most accurate results. Our experience and longevity in the field will attest to our credibility. We have been in business since 1958 and the Banks truck power style is our foundation.The components of a Banks Power Pack differs slightly from one vehicle to another, but the basics include stainless steel exhaust pipes, a low restriction air cleaner, which keeps air flow smooth, and the Banks Quick-turbo turbine housing, which cools the intake air after it comes through the turbo. Banks Power Exhaust Systems are available for a wide variety of vehicles, so whatever model and make your vehicle may be, we have a power kit available for your truck.
