SuperSteer Radius Rods
SuperSteer radius rods are built for specific RV chassis to limit unwanted fore-and-aft axle movement. That is a different job from controlling body roll with a sway bar or side-to-side axle movement with a trac bar.
Where this product fits
Why it matters
Unwanted axle movement can contribute to delayed steering response and a chassis that feels unsettled under braking.
Fitment
Radius rods are chassis-specific structural components. Confirm axle, frame mounts, year and GVWR before ordering.
Leaf-spring suspensions locate the axle as well as support the vehicle. Under load, the springs and bushings can allow some fore-and-aft movement. A properly fitted radius-rod system adds a more direct locating link for that axis of movement.
Because the rod affects axle location through suspension travel, bracket position, fastener torque and clearance are critical. It should not bind the suspension or interfere with brake lines, exhaust, leveling equipment or other aftermarket components.
Good reasons to consider it
- Supported RV chassis with unwanted fore-aft axle movement
- Vehicles that feel unsettled during braking or road transitions after basic maintenance is verified
- Applications with sound spring hangers, bushings and frame mounts
- Installations using the complete chassis-specific bracket system
Confirm before ordering
- Exact chassis and model year
- Front or rear axle application
- Spring, shackle and bushing condition
- Clearance at full suspension travel and steering movement
Frequently asked questions
What direction of movement does a radius rod control?
It limits fore-and-aft axle movement relative to the chassis.
Is a radius rod the same as a trac bar?
No. A trac bar controls lateral axle movement. A radius rod controls longitudinal, or fore-and-aft, movement.
Is it the same as a sway bar?
No. A sway bar resists body roll by linking left and right suspension movement.
Can radius rods fix worn spring bushings?
No. Worn bushings, hangers and mounting points must be repaired first.
Can I order by RV model name?
Not by the coach name alone. Confirm the chassis, year, axle and bracket configuration.
Confirm the exact application
Use the Year, Make, Model selector in the site header when the vehicle or chassis is supported. Read every application note before ordering. If the configuration is unclear, use the technical support form with the vehicle or coach details and photos of the existing suspension.
