TRAILERTAIL
TrailerTails® are the most durable, cost effective and efficient trailer rear drag aerodynamics technology in the history of the trucking industry. TrailerTails® are:
- Certified to deliver 6.6% fuel efficiency gains at 65 mph based on SAE Type II testing validated by the U.S. EPA, sufficient for standalone compliance with 2010 CARB regulations for trailer aerodynamics, and exempt from U.S. DOT length restrictions.
- Proven to perform in drop and hook dry van and refrigerated trailer operations in all weather environments.
- Essential to the profitability of any fleet operation accruing over 30,000 miles per year at highway speeds (between 45 & 75 mph)
TrailerTails® work independently from trailer skirts to reduce the low pressure suction drag which occurs at the rear flat surface of a long-haul trailer. TrailerTails® alone on average save truckers over 8 gallons of fuel savings for every 1,000 miles traveled at highway speeds.

FUEL EFFICIENCY
- EPA-verified SAE Type II testing: 6.6% fuel savings at 65 mph (standard TrailerTail®)
- AeroTrailer package: up to 12%+ fuel savings with skirts and/or other underbody trailer enhancements
- TrailerTail® fuel savings has been third party tested and confirmed by over two dozen independent on-road, SAE, and wind-tunnel tests.
Simple fuel savings calculation:
(Estimated annual trailer mileage)
X (gallons saved / highway mile) [see chart below]
X (price of fuel)
= Total annual fuel savings

REGULATORY
- EPA SmartWay: Approved as advanced rear fairing
- CARB: Achieves standalone trailer compliance
SAFETY
- Improved vehicle stability from streamlined airflow
- Improved driver visibility due to reduced spray from rear wheels
- Reduced tail-gaiting and fatal rear-end collisions due to 4 ft collapsible extension
DURABILITY
- Origami fold: Proprietary origami fold design allows auto-collapse on impact
- Trucker-tough panels: reinforced thermoplastic panels give with impact and bend back to form
- Temperature resistance: highly inert materials maintain their shape in extreme heat and cold
- Weather resistance: with device open, the high-pressure cavity repels precipitation accumulation; panels do not bond with snow and ice and allow water drainage
DRIVER USE
- Proprietary one-touch deployment system or automatic opening
- Closes automatically or manually in less than 4 seconds
