BENDIX® TABS-6™ ADVANCED TRAILER STABILITY
TRAILER ROLL STABILITY FOR AIR- OR SPRING-RIDE SUSPENSIONS
Both Single-Channel and Multi-Channel systems are now available for most spring ride suspensions.
Bendix TABS-6™ Advanced roll stability system provides trailers
with core antilock braking, along with a trailer roll stability
system (TRSP) in one efficient package that’s simple to install
and simple to maintain.
Advanced Performance in a Flexible Package
It’s a fact … rollovers are an issue that can impact every North
American fleet. The Bendix TABS-6 Advanced trailer roll stability
system detects conditions that may lead to a trailer rollover
more rapidly than a driver typically realizes an intervention
is necessary. When that occurs, the system automatically
intervenes by applying the trailer brakes to slow the vehicle and
mitigate a potential rollover.
Bendix TRSP solutions are self-contained units which operate
with a variety of trailer electrical requirements – from 8 to 32
volts – without a separate power converter. The system can be
purchased on new trailers direct from the OEM or retrofitted
onto existing trailers.
For even greater flexibility, custom applications – such as
automatic trailer axle air-suspension control and auto lift
axle – are also available.
Designed for Robust Performance, Flexibility, and
Easy Maintenance
Diagnostics are quick via PLC communication with Bendix®
ACom® Diagnostics or our Bendix® Trailer Remote Diagnostic
Unit (TRDU). Also available J1939 CAN-based diagnostics via
ACom® on Trailer Information Modules.
Choose the Option That’s Right for Your Fleet
Trailer roll stability technology from Bendix ... a flexible offering
of trailer systems for you.
The Single-channel Version
Bendix TABS-6 Advanced is the first-ever, single-channel
trailer stability system. Our most cost effective solution, it’s
designed to be an easy-to-install replacement for the 75%
of trailers built today with a 2S/1M single-channel ABS. The
unit performs both ABS and trailer stability. It can mount
directly to the air tank, on a cross member or frame rail.
Plus, our single-channel option can easily accommodate
four wheel ends with its four delivery ports.
The Multi-channel Version
In this option, most of the
key components – two
modulators, the lateral
acceleration sensor, and the
ECU – are efficiently housed
in an environmentallyprotected central modular
unit, making it simple to install and easy to maintain. A
locking connector cover provides a second line of defense
against water, grime and tampering. Like the single-channel
version, the multi-channel, self-contained unit provides
both ABS and roll stability.
Simply safer
A trailer roll-stability system is designed to help drivers maintain
control of their vehicles in two ways. First, it evaluates conditions
that may lead to a rollover. And second, it intervenes by applying
the trailer brakes automatically, keeping the vehicle in check.

BENDIX® TABS-6™ ADVANCED TRAILER STABILITY
Driving Scenario:
A vehicle enters a curve too fast, on high friction pavement,
resulting in high lateral (side) forces acting at the vehicles
center of gravity (CG). The high friction between the wheels
and the pavement create a “hinge” effect allowing the forces
at the CG push the vehicle over.
Which Trailer System is right for your fleet?
Your Trailer Goal
Need the most cost effective / basic trailer stability?
Already have a 2S/1M trailer ABS system and need to upgrade to trailer stability?
Already have a 4S/2M or 2S/2M trailer ABS system and need to upgrade to trailer stability?
(most tankers)
Have tandem axle trailers and have been susceptible to flat-spotting in the past?
(individual wheel control helps prevent this)
You want to keep ABS functional even when there is one wheel speed sensor faulted?
(possible when multiple wheels are sensed)
You have tridem (three-axle) trailers and want the easiest, fastest solution to trailer stability?
(three delivery ports per modulator make it easy to plumb)
You have air-ride or spring-ride suspension trailers?
(Both SC and MC are available for either air or spring ride suspensions. Requires an external load sensor.)
Retrofit needed?
(can also be ordered on new trailer purchases)
How the Bendix® TABS-6 Advanced MC™ Trailer Stability
System responds:
The Bendix® TABS-6 Advanced MC™ roll stability system
applies pressure to the trailer brakes to reduce vehicle speed
and mitigate the tendency of the vehicle to roll over.

For maximum stability – combine Bendix® ESP on the tractor with Bendix® TABS-6™ Advanced on the trailer
Fleets often ask, "If I have Bendix ESP on the tractor and it controls the trailer brakes, why do I need stability on the trailer?"
That's a good question. Bendix testing shows that a fl eet gets the maximum amount of stability available by having both systems
on the tractor/trailer combination because these systems complement each other. Together they cover a wider variety of potential
rollover scenarios. This is especially applicable for fl eets that run high value trailers, sensitive loads or who want the highest safety
available.
Keep in mind that no stability system replaces the need for alert, safe drivers practicing safe driving habits, as well as continuous,
comprehensive driver training. Drivers are always responsible for the control and safe operation of their vehicle at all times.
The Bendix® TABS-6™ Advanced Trailer roll stability systems make trailer roll
stability available for almost any trailer. Learn More. Talk to your Bendix Account
