"We’ve been using the FlowBelow Tractor AeroKit on over 800 trucks for over two years and have had an overall excellent experience. The system has helped to increase our fleet average fuel economy by approximately 2% and we consider it to be part of our standard tractor spec on both Freightliner and International trucks. On the maintenance side, our mechanics are very pleased with the wheel cover design which provides instant access to the wheel end. Despite the decision to upgrade to chrome wheel covers and to not use a more expensive locking feature, theft has not been an issue for Hirschbach. With over 250,000 miles on every FlowBelow unit we have in the fleet we have only had to replace a few components that got damaged. If and when we need something, FlowBelow has always provided outstanding customer support.
The decision to do business with FlowBelow has made a major positive impact on Hirschbach’s business and we expect that to continue. For future truck orders with Freightliner and International we are planning to spec the system for factory installation."
President, Hirschbach Motor Lines
“We did an extensive 6-month testing period on the FlowBelow Tractor AeroKit for our fleet of about 800 tractors. We found that we are averaging about a 2% gain on MPG with the flow below kits.
The test group was OTR tractors running 48 states with various duties. We saw some added benefits beyond this of reduced road spray, and additional MPG savings when paired to our trailers equipped with skirts or the smart truck system.
We have found that drivers can chain up with these kits installed, and they are very durable. Navajo and many other carriers that are trying to be on the leading edge of fuel economy industry wide are committed to installing these on all new equipment going forward.”
Director of Analytics, Najavo Express
"We performed several fuel and durability tests with the FlowBelow Tractor AeroKit package. First, there was a third-party test that Texas A&M Transportation Institute performed using an MVT-owned International Pro-Star and Utility trailer. The results of that test was a 2.23% fuel savings. As a policy MVT always verifies third party testing with internal testing. The results of the internal testing were positive and in alignment with FlowBelow’s fuel savings claims. Finally, after fuel validation we confirmed durability and driver acceptance with a group of trucks for over a year. In the end, we placed an order with FlowBelow for 1,200 Tractor AeroKits and are currently installed on 80% of our fleet.
Given our experience with the product I would highly recommend making the FlowBelow Tractor AeroKit a standard spec for any regional or OTR operation. There is no better wheel cover or complete system on the market that can help improve the aerodynamics around the wheels of the tractor. "
CEO, Mesilla Valley Transport
“Paul Transportation is a flatbed carrier based in Tulsa, Oklahoma with over 200 tractors in the fleet. We made the decision to deploy Flow Below on a group of trucks in our application and saw a measurable increase in fuel economy. As a next step we then retrofitted over 100 trucks and the product has become a standard spec for new equipment going forward. The average fuel economy of our entire fleet has improved by approximately 1.5 tenths of a mile per gallon after adding Flow Below. Not only does the system save us fuel, it holds up and the drivers like the way it looks.”

“We’ve been using the FlowBelow AeroKit and wheel covers on our trucks for some time now. We are already making a profit on the investment we made and the products have a long life ahead of them. The performance and durability is far better than what I expected and to my surprise, our drivers and mechanics actually like using the product. When I buy new trucks from my dealer, I spec them with FlowBelow.”

“This is the best system that we have used. It makes me most comfortable with the design and the ease of getting the covers on and off is superior to any other system we have used. FlowBelow’s wheel covers can be removed in a matter of seconds to facilitate roadside inspections.”

"We have been running the FlowBelow kits for about 6 months and watched our MPG increase as high as 9 mpg on some trucks. We are extremely satisfied with the product, customer service and we highly recommend the FlowBelow AeroKit."
President, Zeller Transportation
“Over the past decade, we have improved the fleet average fuel economy of Cooper Freight by over 3 miles per gallon. One of the main ways we’ve been able improve our fuel efficiency is by reducing the aerodynamic drag of our tractors and trailers. With that said, we didn’t make these changes overnight. For example, when we first became aware of the FlowBelow Tractor AeroKit system we decided to test them out on a group of trucks. In order to be confident in the fuel savings we installed the product on a dedicated sample size of trucks and tracked performance for over a year to verify both fuel savings and durability. After testing the first group of trucks we then tested a second group of trucks to gain more confidence in the data. We confirmed that the fuel savings of the product for our fleet was approximately two-tenths of a mile per gallon. In addition, the drivers and mechanics are very pleased with the accessibility of the FlowBelow quick-release design. Going forward we spec FlowBelow on every new truck we purchase.”
General Manager, Cooper Freight
“The fuel economy of our fleet of tractors has improved by over 2/10th mpg with the FlowBelow Tractor AeroKit. The products are incredibly durable, easy to use, and install in 45 minutes per truck. The design and functionality of FlowBelow’s wheel covers and Tractor AeroKit is superior to any other system I’ve seen or used. Josh and his team at FlowBelow will not let you down.”

Owner / Operator Customers
"I can't see any reason why you wouldn't use the FlowBelow AeroKit. It serves several purposes. The first one is increased fuel mileage by smoothing out the airflow (across the tractor wheels). In addition this is one of the easiest wheel covers to take off and inspect the wheels hub. Being a great improvement over many of the designs out there. It's light, easy and effective."
Freightliner Team Run Smart / Albert Transport Inc.
"We've had the FlowBelow kit for 2.5 years and we are very pleased and satisfied. We've had great success with the kit and recommend it to anyone looking to save fuel. The product is extremely durable and easy use. The customer service is excellent- good 'ol Texas hospitality!"
John and Annette Howe
"After tons of research that included talking to drivers and reading literature from at truck shows, we purchased front and rear wheel covers from FlowBelow. We are extremely happy with the quality of the product, customer service, and fuel savings we have seen to date. After running with Tractor AeroKit for about a year on our straight truck, we have noticed an improvement of 2-3 tenths miles per gallon."

"I'm a company driver for Koch Trucking and have had the FlowBelow kit on my truck for a little over a year. I've seen an increase in my MPG and the product makes my rig look pretty sweet. It's easy to take on and off and the product is super durable. I would definitely recommend this product to anyone who wants to save fuel!"

Driver, Koch Trucking
"I have been running the FlowBelow AeroKit since May 2014 and it has been well worth the investment. I truly believe in this product and it has proven itself time and time again. This industry is a matter of pennies and every penny you save multiplied by the number of miles you drive adds up. As this industry changes, it becomes a numbers game and I am going after every penny I can. The FlowBelow system helps me save fuel every mile I drive."
Contractor, JCT Trucking
"We began installing FlowBelow Products on all of the truck and trailers in our fleet well over a year ago. The Tractor AeroKit product was installed on every truck in the fleet, and the FlowBelow quick-release wheel covers were also installed on every trailer in the fleet. The product has easily exceeded my expectations in terms of fuel savings. We have had very few issues, but the customer support we received from the FlowBelow team was truly impressive.
Currently we have nearly 400 sets of wheel covers intstalled on our trailers. One of the major benefits of using the FlowBelow wheel covers has been the ability to maintain instant access to our wheel ends for regular maintenance and inspection. Unlike other wheel covers on the market, the FlowBelow design has superior durability, doesn't damage the wheels, and actually looks good on our equipment. With the installation of FlowBelow products and other improvements we have done to our fleet in the the past 2 years, we have seen dramatic improvement in the overall fuel efficiency of equipment."
"I’m seeing an improvement in mpg’s with FlowBelow with my step deck trailer. Visually... looking at the truck and trailer... it’s a no brainer. Just look down the side of the truck and you can visibly see how the Tractor Aerokit makes the whole unit streamlined."
"I've had the FlowBelow system for 18 months now and I'm upset that I didn't purchase it sooner. When I think about the money I left on the table the 2 years and hundreds of thousands of miles I could have had it saving me money. Doing primarily Northern routes I was concerned it would build up with snow and ice but surprisingly it doesn't. I suppose that is a testament to its aerodynamics. Honestly couldn't be more satisfied with the system and would highly recommend it, let me say that again I would highly recommend it."
"It has been three months since I installed the FlowBelow system on my tractor and trailer wheels. I must say that I was impressed with the packaging, instructions, and the engineering. Everything fit together like it should've... my overall experience was a good one. My fuel mileage totals are trending in a positive direction, up. At this early stage I will say 1 to 2/10th increase."
David W. Frey
"We dealt with a gentleman named Mark Stelling. He was my contact from the sales side all the way to the installation and beyond and was professional. When we decided to purchase the system he offered to install it at their facility in Austin TX, which we did and they took great care of us. We have only had the system a couple of weeks, but I can tell a difference in fuel consumption already. It's a great system especially if your unable to haul trailers with side skirts. By my calculations the system will pay for itself in a year or less. As an owner operator I highly recommend this system to everyone."

I wanted to take a few minutes to give you some feedback on both your customer service and the products I bought.
First of all, your customer service is fabulous – we had unique questions that were dealt with promptly and accurately by your staff, who then helped us make the purchase and get it shipped right out. When we reconfigured the truck, I happened to be near your headquarters in Austin, so I stopped by and was able to meet your staff while getting my new parts. It was easy to see that your crew is passionate about their products!
We are running a 3-axle 40-foot long straight truck, and we use the Flow Below Tandem Fairings and Wheel Covers. Installation was as easy as your staff and marketing materials stated that it would be, and the different hole patterns in the Tandem Fairing frame and mounts made it easy to get ours mounted exactly as we needed. I especially like how robust the frame is – I don’t expect to be replacing this any time soon!
The wheel covers are one of the best designs I’ve seen in years. The most common type, the framed fabric covers that are held on with hook & loop fasteners, have many shortcomings (including difficulty in fitting them, abrasion damage to the aluminum wheels, and that they never look clean.) Your covers are the complete opposite. They were easy to install for the first time (10 minutes with hand tools), fit securely without actually contacting the wheels, and best of all, have received universal approval from the technicians at every Love’s Truck Stop Tire Pass lane I’ve visited. The technicians really appreciate just how easily they come off and on, and even after driving in severe weather all winter, we never had a problem with the mechanism that keeps the caps in place.
Finally, let’s talk about performance. We are seeing an increase in fuel economy since fitting your components, and even more impressive, the truck is noticeably more stable in crosswinds and when passing or getting passed by other trucks.
In an industry that often sees inflated claims or unrealistic commentary, your company is the exact opposite. If anything, you have actually understated just how terrific your products are, and how well they work. Thank you for making them.
