Dual Force Balancing

Delivers lower rolling resistance, longer tire wear and the smoothest ride.

RWC’s Twist & Lock Wheel Covers and Eco Flaps are backed by a 2-year warranty for Class 8 tractor and trailer applications.
IMI’s FLEXX is warranted for the life of the tractor tires.


The combined savings from fuel and tire life extension with the MPG SMART PACK™ total at least $6,000 over a 4-year lease or owner cycle on the tractor.

For trucks traveling 2,000 or more miles per week, the combined fuel savings from this MPG SMART PACK™ is at least 7 to 8 gallons of diesel per week.

Since the MPG SMART PACK™ can be purchased and installed for less than the fuel cost to operate a truck for 3-4 days, utilizing these products together results in great ROI with no ongoing maintenance required. This 3-product combination requires no trailer aero investment to achieve the fuel and maintenance savings.

In addition to fuel savings, the 3-product combination lessens vibration for the smoothest ride, plus reduces spray and corrosion. The adaptive wheel-end dual force balancer also extends tread life on all tractor tires by up to 20 percent or more.

Pricing for the MPG Smart Pack starts at $474.40 for a 10 tire kit. (Does not include installation)


In September 2017, NACFE sponsored the coast to coast Run On Less fleet demo of best practices for over-the-road fuel economy.

Results were featured at the premier of the North American Commercial Vehicle show in Atlanta. 90% of the participating fleets equipped their trucks with wheel covers, aerodynamic flaps and tire balance solutions to help surpass 10 MPG fuel economy. (

In the same month, independent 3rd party testing of the MPG Smart Pack™ on both tractor and trailer at 62 MPH demonstrated highway fuel savings above 5%.
