Our Side Underride Devices offer vehicle occupants protection should a side collision occur between large semi-trailers and passenger vehicles. Tested by the Institute for Highway Safety (IIHS), underride was prevented at a speed of 40 mph. As a result, should a side impact occur with an AngelWing Side Guard, the vehicle will be prevented from penetrating the space between the ground and the trailer body and avoid compromising the occupant space as it will remain intact, protecting the vehicle occupants inside.

AngelWing’s dynamic design is intended to stop and absorb the energy of the vehicle and engage the vehicle’s built-in safety systems like seatbelts, airbags, crumple zones or anti-crash avoidance systems (if equipped).

AngelWing Side Underride Devices are available in complete kits,  sold by length or by individual components.  To maintain fuel efficiency, guards be integrated with most existing side skirts, maintaining CARB or SmartWay™ certification, if applicable.  If one is needed, they can be purchased directly as an option.

Pricing for a 53′ semi-trailer is $3,990, shipping and hardware included.  Fleet, volume discounts and evaluation trails available.

AirFlow Deflector’s AngelWing side guards can be purchased directly or through our dealership network.

AirFlow Deflector Side Guards offer pedestrians, cyclists, and motorcyclist’s side underride protection in the event of a side collision with large city trucks. Side Guards are sold in kits by length and strength/force deflection levels ranging from 220, 440, or 660 lb force / energy deflection. This is the amount of energy that is absorbed by the mounted guard structure before they distort or break. Individual components are also sold separately to meet vehicle requirements.

Side guards are available in fiberglass, aluminum or steel. All of our systems are certified compliant and meet the required budget/strength standards needs to suit the project. Our 440 and 660 force systems meet or exceed the “Volpe” recommended standards as required by many city ordinances like New York City, Chicago, Washington and Boston. 

Installing truck side guards to your fleets such as sanitation, delivery, and other large trucks can significantly decrease the instance and risk of injury or fatality should a side impact occur.

Pricing starts at $425.00 per side for our “220” standard rail system,  plus shipping. All kits include all required mounting hardware.

AirFlow Deflector Side Guards can be purchased directly or through our dealership network.
