BENDIX® ETRAC™ AUTOMATED AIR BAG TRANSFER SYSTEM FOR 6X2 SUSPENSIONS
Weigh Less. Haul More. Keep Moving.
Sometimes you just need some extra traction to get the job done. Whether it's a slippery uphill grade, an inclined loading dock, or anywhere conditions mean your vehicle needs the extra boost to avoid being stuck, the Bendix® eTrac™ automated air bag transfer system for 6x2 suspensions can help.
Spec Smart. Spec eTrac. Haul More.
Today, fleet operators know how important it is to continue to enhance their bottom line. One good decision can make a big impact. With the Bendix eTrac system, you’ve made the right choice. With the eTrac system, your fleet can haul approximately 500 pounds more freight per vehicle – and more freight means more revenue. That’s because now you can spec a 6x2 vehicle with the eTrac system instead of a 6x4 vehicle alone.
When Traction Control Engages, So Does eTrac.
Sometimes, in slippery conditions, 6x2 vehicles can't pull away on an inclined ramp or up a hill because of drive wheel spin. Today, the driver must manually push a
–one that happens all too often – can severely damage the driven axle or driveline, meaning vehicle downtime and unexpected maintenance expense. This won't happen with the eTrac system.
The Bendix eTrac system is automatically activated when traction control is active. It is ideal for over the road and long haul fleet operators. Designed for 6x2 tractors and trucks, the eTrac air pressure transfer system fully automates what currently is a manual operation. When added to Bendix® Smart ATC™ (automatic traction control), the eTrac system automatically engages and disengages – without driver input – the vehicle’s air bag pressure transfer system during

How Does It Work?
Automatic Mode – Typical Operation
When the ATC Mud/Snow switch is OFF, the Bendix eTrac system is in “automatic” mode. This means when ATC becomes active, the eTrac system automatically engages to help the vehicle pull away from a slippery road surface.
When ATC becomes active, the system will automatically perform the air bag transfer until the vehicle exceeds 25 MPH or five (5) seconds after the ATC event has ended. The automatic disengagement feature helps prevent overburdening the driven axle or driveline because the air bag air pressure transfer was active for too long.
Semi-Automatic Mode – When the driver knows it’s slippery
When the driver activates the ATC Mud/Snow switch, the Bendix eTrac system goes into
Air pressure transfer to the driven axle airbags is automatically limited by the system. This pressure limit is determined by the vehicle OEM at installation and cannot be changed by a fleet.
