When you’re towing large travel trailers, toy haulers, or heavy equipment trailers, stability isn’t optional—it’s essential. The Curt Round Bar Weight Distribution Hitch with Integrated Lubrication (10K–14K) is built for serious towing applications, leveling your tow vehicle and trailer by redistributing a portion of the tongue weight across all axles for safer, more controlled handling.
Designed for heavy-duty RV owners, contractors, and anyone towing in the 10,000 to 14,000 lb. range, this system enhances steering control, braking performance, and ride comfort. With forged steel spring bars, a precision-adjustable head, built-in lubrication points, and sway control compatibility, it’s a professional-grade performance upgrade that delivers confidence mile after mile.
If you’re investing in high-capacity truck accessories for demanding towing jobs, this weight distribution hitch is engineered to meet the challenge.
Key Features
- 10,000–14,000 lbs. Towing Capacity – Engineered for heavy trailers with up to 1,400 lbs. tongue weight for superior load control
- Integrated Grease Zerk Fittings – Built-in lubrication points reduce friction and extend component life with easy maintenance
- Forged Round Steel Spring Bars – Provides dependable strength and consistent weight transfer under high loads
- Sway Control Compatible Head – Built-in tabs allow quick addition of one or two sway control units for enhanced stability
Features & Benefits
Heavy trailers can create rear sag, front-end lift, and compromised steering response. The Curt round bar weight distribution hitch corrects this by distributing tongue weight evenly between the tow vehicle’s front axle, rear axle, and the trailer axles. The result is a level stance, improved braking efficiency, and safer highway handling—especially at higher speeds or in crosswinds.
This model is rated for 10,000–14,000 lbs. gross trailer weight (GTW) and 1,000–1,400 lbs. tongue weight (TW), making it ideal for larger RVs, campers, and equipment trailers.
The system’s strength starts with its heavy-duty fabricated steel head, engineered for precise adjustability and long-term durability. The adjustable head allows you to fine-tune the tilt for optimal weight transfer and leveling.
A standout feature of this hitch is its integrated lubrication system. Built-in grease zerk fittings are positioned at the spring bar pivot points, allowing for easy, continuous lubrication. Proper lubrication (grease must be applied to the zerk fittings) ensures smoother operation, quieter performance, and reduced wear over time.
The forged round spring bars mount from the underside of the hitch head and are built for reliable strength under heavy loads. The chain-style hookup brackets and snap-up design allow easy leveraging and adjustment of the spring bars, giving you precise control over tension and ride height.
For enhanced vehicle protection and towing stability, the head includes integrated sway control attachment tabs. These tabs accept one or two CURT sway control units (17200, sold separately), helping reduce side-to-side trailer movement caused by wind, road conditions, or passing vehicles.
The included 2" x 2" adjustable shank fits most Class 3, Class 4, and Class 5 receiver hitches and can be flipped to provide the necessary drop or rise. For heavy-duty applications, a 2-1/2" x 2-1/2" replacement weight distribution shank is available separately to match larger Class 5 receivers.
To ensure long-term durability, this hitch is finished in a carbide black powder coat, providing excellent resistance to corrosion, chips, and harsh environmental conditions.
