UltraSteer tag axles are fully integrated and precision tuned to react to turns and maneuvers of the coach—establishing a new standard for premium RV ride and handling. From safety and comfort to reduced tire wear and lower maintenance, this is the RV driving experience you want. And it’s only from Freightliner Custom Chassis.
More than an ordinary tag axle, UltraSteer follows the ideal turning path of the front suspension, improving ride and handling and providing full control and precise maneuvering in all conditions.
By providing increased lateral stiffness over the competitor’s narrow track suspension arms, UltraSteer delivers improved handling and safety in sudden maneuvers.
UltraSteer’s outboard-mounted design is more reactive to roll input, greatly enhancing ride and handling over competitors’ inboard-mounted shocks.
In contrast to rear-mounted tie rods that can still cause tire scrub, UltraSteer’s forward-mounted tie rods and correct steering geometry enable the inside wheel to have a 12° turning angle and follow the ideal turning path— eliminating tire scrub.
UltraSteer provides up to 17% reduction in curb-to-curb turning radius as compared to an ordinary fixed tag axle—140% improvement over the competition. And, it has a 20% tighter turning angle than the nearest competitor.
Wheels straighten and lock automatically at 20mph and in reverse, utilizing air chamber locking pin and plate.
These bushings increase suspension life and are maintenance-free.
Quik-Align® allows for easy alignment without the use of shims.
