If you’re towing a travel trailer, pop-up camper, or light-duty utility trailer and want a safer, smoother ride, the CURT Round Bar Weight Distribution Hitch with Integrated Lubrication is a smart, confidence-boosting upgrade. Designed to level your tow vehicle and trailer by redistributing a portion of the tongue weight across all axles, this system improves steering control, braking performance, and overall towing stability.
Ideal for campers, weekend adventurers, and anyone hauling in the 5,000–6,000 lb. GTW range, this weight distribution hitch enhances vehicle protection while delivering better handling on highways and backroads alike. By correcting rear-end sag and promoting a level stance, it reduces strain on your suspension and helps maintain proper front-axle traction — something every driver can appreciate when towing.
What sets this system apart is its integrated lubrication design, featuring built-in grease zerk fittings that allow continuous lubrication at the spring bar mounting points. That means smoother operation, reduced wear, and longer service life compared to standard dry-contact systems. Built with forged steel spring bars, a fabricated steel head, and protected by a durable carbide black powder coat finish, this is a heavy-duty piece of towing equipment engineered for long-term reliability.
If you’re looking to improve towing control, protect your vehicle, and upgrade your trailering setup with dependable truck accessories designed for real-world use, this CURT weight distribution hitch delivers performance where it matters most.

- Weight Redistribution System – Levels truck and trailer to improve steering, braking, and overall towing stability
- Integrated Grease Zerk Fittings – Allows easy, continuous lubrication for smoother operation and extended component life
- Forged Steel Round Spring Bars – Provides dependable strength and reliable load support up to 6,000 lbs. GTW
- Adjustable Shank & Snap-Up Brackets – Enables precise leveling and easy setup for a customized towing configuration
Features & Benefits
Level Towing for Safer, More Controlled Driving
A properly leveled towing setup isn’t just about appearance — it directly impacts safety and performance. This weight distribution hitch redistributes a portion of the trailer’s tongue weight across all axles of the vehicle-trailer combination.
Benefits include:
- Reduced rear sag
- Improved front axle traction
- Enhanced steering response
- More balanced braking
- Reduced suspension stress
Whether you’re heading to a campsite or hauling recreational gear, maintaining a level ride improves control and reduces driver fatigue.
Integrated Lubrication for Smoother Operation
Unlike traditional weight distribution hitches that rely solely on manual greasing at disassembly, this system features built-in grease zerk fittings at the spring bar mounting locations.
This allows:
- Easy lubrication without major disassembly
- Reduced friction and wear
- Smoother bar articulation
- Extended component longevity
Grease must be applied to the zerk fittings to ensure proper lubrication and optimal performance.
Heavy-Duty Steel Construction
Strength begins at the head. The heavy-duty, fabricated steel head is engineered for durability and precise adjustment. The round, forged steel spring bars install from the underside of the head and are designed to handle tongue weights between 500–600 lbs. and trailer weights up to 6,000 lbs. GTW.
The entire system is protected by a carbide black powder coat finish, providing resistance against corrosion, road debris, and harsh weather conditions — essential for long-term vehicle protection.
Sway Control Ready
The head includes built-in sway control attachment tabs, allowing you to add one or two CURT sway control units (#17200) if additional sway reduction is desired.
This modular capability gives you the flexibility to upgrade as your towing needs evolve.
Receiver Compatibility
- Fits standard 2" x 2" receiver tubes (Class 3, 4, and 5 hitches)
- Compatible with optional 2-1/2" x 2-1/2" WD replacement shank for heavy-duty applications
This makes it a versatile towing accessory for a wide range of trucks and SUVs.
