How the Sway Control Ball Works
Several components work together when the CURT 40093 sway control ball is doing its job, and understanding that interaction clarifies how lateral trailer movement is reduced.
It attaches at the 1-1/4-inch ball, integrating with the sway control unit to apply frictional resistance during oscillation. How does it help you tow safer?
- Friction pads engage, dampening side-to-side motion.
- Ball mount interface transfers corrective force to the tow vehicle.

Frequently Asked Questions
Can It Be Used With Gooseneck Trailer Couplers?
No, it is not compatible with gooseneck couplers; gooseneck compatibility is lacking. Installation tips: use only recommended hitch or sway tab mounts, confirm shank dimensions, secure with provided nut and lock washer to guarantee proper sway control.
Does the Ball Require Periodic Lubrication?
Yes; periodic lubrication is recommended: inspect before trips, lubricate sparingly, and reapply seasonally. For lubrication frequency, follow use intensity and environment. Maintenance tips include cleaning contact surfaces and checking fasteners for secure mounting.
Is There a Warranty Beyond Amazon Returns?
No, only Amazon’s 30-day return guarantee is noted; manufacturer warranty details are not specified. Customers are advised to contact Curt Manufacturing customer support for warranty details and potential coverage beyond the Amazon return policy.
Can It Remain Installed During Car Washes?
Absolutely — it can stay installed during car washes; enthusiasts almost dramatize its resilience. Car wash safety is generally fine, and installation convenience means quick removal if desired, though rinsing and drying prevent premature corrosion.
Does It Affect Trailer Tongue Weight Limits?
No, it does not change tongue weight limits; the sway control affects lateral stability, not static tongue weight. Users should still observe vehicle and hitch tongue weight ratings while employing sway control for improved towing stability.
