Part# UTW22R - Rear UltraTrac Trac Bar for Workhorse W20, W21, W22, W24


The UltraTrac Rear Trac Bar mounts from the frame rail to the rear axle to prevent wandering or "tail wagging the dog" issues in windy conditions or by passing trucks. This is a very popular upgrade to the Workhorse W-series chassis as it provides a significant increase in stability of the coach, inspiring driver confidence and less work at the wheel. Assembled from heavy-gauge steel and polyurethane bushings, this is a "no-drill" installation. Powder coated for long lasting protection and made Proudly in the USA.

Can I still use my Lippert leveling system which raises the rear 3 to 4 inches when leveling the Motorhome? Will the leveling system put undo stress the rear track bar or Chassie? ( Mike Binkley, 07/16/2018 )
Yes the bar will articulate with the suspension up and down. ( Support )
Can this be mounted on the driver side? It does not appear there would be enough clearance with the exhaust pipe on the passenger side. ( Don, 06/01/2018 )
The UTW22R will not install on the driver side as it utilizes the bolt pattern on the differential to mount to the passenger side and is not reversible. The bend in the rod usually is sufficient to clearance the exhaust pipe. ( Support )
I have a 2005 Winnebago Adventurer 35U and want to install the trac bar but the large exhaust pipe goes down the passenger side of the differential, so it looks like the connecting bar between the frame and diff is blocked by the exhaust pipe.


( Neil, 03/19/2018 )
The UTW22R has a "dog leg" bend in it to clearance exhaust the goes over the axle. If the exhaust has been modified in such a way that the rod will not clearance, you would have to reroute the exhaust to before the rear axle. ( Support )

can this be installed in conjunction with the 1259-108 1-1/2” rear anti- sway bar ( 2008 W24 chassis)

( Chris, 09/23/2015 )

Yes sir they are compatible with each other. Just so you know, there is an 1-3/4" anti-sway bar available, 1259-109.
