Icon 01648 Aero Shield: Best overall for mpg

The Icon 01648 Aero Shield stands out as the most balanced option for farmers who demand immediate results at the pump. Its design focuses on a smooth, sweeping curve that effectively bridges the aerodynamic gap between the truck cab and the front of a feed trailer. By directing air over the top of the load rather than letting it smash into the flat front of a trailer, it significantly reduces the engine’s workload during highway transit.

Constructed from high-impact plastic, this unit is lightweight enough to avoid stressing the roof of the cab while remaining rigid under heavy wind pressure. The adjustable angle is a critical feature for those who switch between different types of trailers, from low-profile utility trailers to taller, enclosed grain haulers. This versatility ensures that the aerodynamic “sweet spot” is always achievable regardless of the specific haul.

Maintenance is straightforward since the surface is easy to wipe down after a dusty day in the fields. The assembly arrives with most of the hardware needed for a standard installation, minimizing the time spent in the shop. It is the ideal choice for a farmer who prioritizes a quick return on investment through fuel savings without sacrificing the ability to customize the setup for various loads.

Taylor Wing T400: Most durable metal option

When the priority is longevity and resistance to the physical rigors of farm life, the Taylor Wing T400 is the undisputed heavy hitter. Fabricated from high-grade aluminum, this deflector shrugs off the UV damage and temperature fluctuations that eventually cause plastic models to become brittle. It is built to survive years of exposure to the elements, from scorching summer sun to sub-zero winter mornings.

The T400 utilizes a classic wing design that provides consistent lift and air redirection. Because it is metal, it offers a level of structural rigidity that prevents fluttering or vibration at higher speeds, which can be a common annoyance with lighter materials. This stability translates to a quieter ride in the cab, a small but appreciated luxury during long hauls to distant suppliers.

This is the correct choice for the owner who plans to keep their current hauling rig for the next decade. While the initial cost may be higher than plastic alternatives, the durability ensures it will likely outlast the truck itself. If the farm environment involves low-hanging branches or frequent debris, the Taylor Wing T400 provides the necessary peace of mind.

Grand General 90150: Best for classic cabs

Older farm trucks often feature boxier cab designs that do not play well with modern, hyper-curved aerodynamic accessories. The Grand General 90150 offers a stainless steel solution that complements the aesthetic of classic rigs while providing modern efficiency benefits. Its polished finish and traditional lines look right at home on a vintage workhorse without appearing like an aftermarket afterthought.

Beyond its looks, the 90150 is highly functional, utilizing a reinforced bracket system that handles the unique roof contours of older truck models. Stainless steel construction provides excellent corrosion resistance, which is vital for trucks that might spend their winters on salted country roads. The material choice also means it can be buffed back to a mirror shine even after years of neglect.

This deflector is specifically for the enthusiast who takes pride in a well-maintained classic fleet. It proves that improving fuel economy doesn’t require compromising the character of a vintage vehicle. If the goal is to save on feed transport costs while maintaining a professional, classic appearance at the coop, this is the definitive option.

Belmor Aeroshield II: Best for severe weather

Hauling feed doesn’t stop when the weather turns, and the Belmor Aeroshield II is engineered specifically for those challenging conditions. Made from a specialty smoke-tinted polycarbonate, it is designed to withstand impacts from road salt, gravel, and frozen slush without cracking. The material retains its flexibility in extreme cold, a feature that prevents the shattering often seen in cheaper acrylic versions.

The low-profile wrap-around design does more than just move air over the trailer; it helps deflect bugs and light debris away from the cab’s roofline. This keeps the truck cleaner and reduces the risk of stone chips on the upper cab paint. The smoke finish also helps cut down on glare during sunrise or sunset hauls, which is a subtle but important safety benefit for tired drivers.

This model is the right fit for farmers in northern climates or high-altitude regions where winter starts early and ends late. It offers a “set it and forget it” reliability that handles the worst Mother Nature can throw at it. If the local routes involve gravel roads and unpredictable weather, the Belmor Aeroshield II is the insurance policy the truck needs.

Fuel-Squeezer FS-100: Best for compact cabs

Not every feed haul requires a heavy-duty dually, and the Fuel-Squeezer FS-100 is designed with the smaller pickup owner in mind. Many hobby farmers rely on mid-sized or standard half-ton trucks that can be overwhelmed by oversized commercial deflectors. The FS-100 provides a scaled-down solution that offers significant drag reduction without looking disproportionate or adding unnecessary weight.

One of the standout features of this model is its ease of removal and storage. If the truck serves as a primary commuter vehicle during the week, the deflector can often be adjusted or removed relatively quickly when not towing. This flexibility is essential for the part-time farmer who needs their vehicle to wear many different hats.

Choose the Fuel-Squeezer if the primary hauling is done with a standard pickup and a manageable trailer. It provides a noticeable boost in stability when pulling against a headwind, making the truck feel more planted on the road. It is the practical choice for those who want the benefits of a professional hauler on a smaller, more versatile scale.

TurboWing Model 1100: Best for heavy hauling

When the trailer is significantly taller than the truck cab, a standard deflector often isn’t enough to clear the air gap. The TurboWing Model 1100 is engineered with a high-lift profile specifically designed to handle these large-volume trailers. It creates a massive “air tent” that bridges the gap between the cab and the load, preventing air from swirling into the bed or hitting the trailer face.

The 1100 is known for its multi-angle adjustability, allowing the driver to fine-tune the airflow based on the specific weight and height of the feed load. This is particularly useful when hauling palletized bags of grain that sit high in the trailer. The increased surface area of the wing provides the necessary leverage to move a large volume of air efficiently.

This is the specialized tool for the farmer who moves large quantities of feed over long distances. If the trailer frequently looks like a giant wall behind the truck, the TurboWing is the only model that will provide a substantial difference in performance. It is a serious piece of equipment for those who treat their feed transport as a major logistical operation.

How to Choose the Right Height for Feed Hauling

Selecting the correct height for a cab deflector requires a clear understanding of the “air gap” between the truck and the trailer. The goal is to create a seamless transition where the air flowing over the cab is directed just over the leading edge of the trailer. If the deflector is too low, the air will still slam into the trailer’s upper face; if it is too high, it creates unnecessary drag of its own.

Measure the distance from the roof of the cab to the top of the trailer while the trailer is hitched and level. Most effective setups aim to have the top of the deflector sit roughly two to four inches below the top of the trailer’s height. This allows the air to “kick” upward and clear the trailer without creating a massive vacuum behind the cab.

Consider the typical load weight, as a heavily loaded trailer will squat the rear of the truck, effectively raising the front of the trailer relative to the cab. Adjusting the deflector height based on the loaded state, rather than the empty state, ensures the best efficiency when it matters most. Using a deflector with an adjustable pitch allows for fine-tuning as the suspension settles under the weight of several tons of grain.

Step-by-Step Installation for Secure Mounting

A poorly mounted air deflector is a safety hazard and a source of annoying whistles or vibrations. Start by thoroughly cleaning the roof of the cab to ensure any mounting pads or brackets have a solid, debris-free surface to grip. Mark the centerline of the cab and the deflector using painter’s tape to ensure the unit is perfectly centered, as an off-center mounting will cause the truck to pull to one side at high speeds.

Follow the manufacturer’s torque specifications for all hardware, especially if the kit requires drilling into the cab or using heavy-duty clamps. Use a thread-locking compound on all bolts to prevent them from vibrating loose over washboard farm roads. If the deflector uses a gutter-mount system, ensure the clamps are seated deeply and do not interfere with door seals or window operation.

Once the unit is mounted, take a short test drive at moderate speeds before heading out on a long haul. Listen for excessive wind noise and check for any movement in the brackets once the vehicle is stopped. A final check after the first 50 miles of hauling is recommended to ensure the wind pressure hasn’t shifted the alignment or loosened the fasteners.

Safety Tips for Hauling Tall Feed Loads Safely

Adding a cab deflector changes the aerodynamic profile of the vehicle, which can affect how the truck handles in crosswinds. While the deflector improves forward efficiency, it also increases the side-profile surface area. Drivers should be prepared for more significant “push” from side gusts when passing large buildings or exiting wooded areas into open fields.

Always check the clearance of the deflector when pulling into barns or under low-hanging trees. It is easy to forget that the truck now sits several inches higher than it did before, and a collision with a low beam can cause structural damage to the cab roof. Marking the new total height of the truck on a small sticker inside the cab is a helpful reminder for the driver.

Regularly inspect the mounting points for signs of stress or fatigue, especially after driving through high winds or heavy storms. The constant upward pressure from the wind creates significant lift, which can strain the roof’s sheet metal over time. Ensuring that the load in the trailer is balanced and centered will work in tandem with the deflector to provide the most stable towing experience possible.

Calculating Fuel Savings on Your Farm Routes

To truly see the value of an air deflector, a farmer must track fuel consumption over several consistent trips to the feed mill. Start by recording the average miles per gallon (MPG) during three typical hauls without the deflector installed. Once the deflector is mounted and adjusted, repeat the tracking over the next three trips under similar weather and load conditions.

Most users see an improvement of anywhere from 0.5 to 2.0 MPG depending on the truck, trailer, and average speed. While this may seem small, it adds up quickly for a hobby farm that makes weekly or bi-weekly runs. For example, if a truck averages 10 MPG and sees a 10% improvement, over 5,000 miles of hauling, that results in a savings of 50 gallons of fuel.

Factor in the reduced wear and tear on the engine and transmission as well. When the truck doesn’t have to fight as much wind resistance, operating temperatures stay lower and the transmission shifts less frequently. These long-term mechanical savings often exceed the raw fuel savings, making the air deflector one of the most cost-effective upgrades available for a working farm vehicle.

Optimizing a hauling rig with the right air deflector is a practical investment that pays dividends in both fuel economy and mechanical longevity. By matching the equipment to the specific needs of the farm’s routes and trailer types, one can turn a standard truck into a specialized transport tool. Consistency in maintenance and careful adjustment will ensure that every trip to the feed store is as efficient as possible.
