CURT Manufacturing 17200 Sway Control Kit
Best for: RV owners who want a standalone sway control upgrade that can fit various hitches. Why selected: this kit directly limits lateral trailer movement, lowering sway without requiring replacement of the entire hitch system. The included sway tab mount broadens compatibility with different ball mounts. Caution: verify compatibility with your current weight-distribution setup to ensure proper installation.
CURT 17063 Round Bar Weight Distribution Hitch
Best for: travel trailers needing level towing and integrated sway control. This model distributes tongue weight and uses a built-in sway control kit (#17200) to reduce sway. Better for: RVs with a heavier tongue load seeking smoother, more controlled handling. Caution: lubrication is continuous—grease zerks require regular maintenance for optimal performance.
CURT 17062 MV Round Bar Weight Distribution Hitch
Best for: RVs needing reliable weight redistribution with easy lubrication access. This hitch levels both tow vehicle and trailer by redistributing weight and includes sway control to help reduce sway. Choose this if you want a straightforward grease-zerk update for ongoing maintenance. Limitation: overall capacity is up to 10,000 lbs GTW, so ensure your trailer fits within that range.
CURT 17422 Short Trunnion Bar W.D. Hitch
Best for: RVs with higher gross vehicle weight and those needing sturdy sway control with compact tank space. This model uses 28-3/8″ trunnion-style, forged steel spring bars to deliver robust stability and sway reduction. Why choose: strong construction supports heavier loads and maintains balance during turns. Caution: larger footprint may not fit smaller trucks or lightly equipped vehicles.
Weight Distribution Hitch With Sway Control Bar (FAHKNS)
Best for: budget-conscious buyers who still want effective sway control. This 14,000 lb-capacity hitch features a balance-focused design and anti-sway elements for RV stability on long hauls. It coordinates tongue weight and trailer weight for more predictable handling. Caution: ensure compatibility with your existing hitch shank size (2-inch) and ball size (2-5/16 inch).
Dollate Weight Distribution Hitch With Sway Control
Best for: RV owners seeking a comprehensive sway-control system at a value price. This 14,000 lb-rated hitch balances trailer and tow vehicle weight to improve steering and braking. It reduces sway with a robust spring-bar setup. Caution: validate the system’s compatibility with your trailer’s weight and hitch configuration before purchase.
Nilight Adjustable Sway Control Kit
Best for: users who want adjustable sway resistance with on/off capability. The Nilight kit offers double friction pads and wide adjustability to suit different trailer weights and road conditions. It’s particularly suitable for owners who tow in varying environments. Caution: effectiveness depends on correct setup; improper adjustment can reduce control rather than enhance it.
Buying Guide: Key Considerations When Choosing A Sway Bar For RV
- Weight rating and compatibility: Verify GTW ( Gross Trailer Weight ) and TW (Tongue Weight) ranges, shank size, and ball size to match your trailer and tow vehicle.
- Type of sway control: Decide between integrated sway control within a weight-distribution hitch vs. a standalone sway control kit. The latter can be added to existing hitches in many cases.
- Lubrication needs: Some models include grease zerks for ongoing lubrication, which affects maintenance and performance.
- Installation complexity: Some kits are quick upgrades; others require more extensive hitch reconfiguration or welding. Consider your DIY comfort level.
- Durability and materials: Forged steel and solid spring bars typically offer stronger sway resistance in demanding conditions.
- Road conditions and climate: On/off friction or adjustable pads can adapt to crosswinds and icy roads; plan for seasonal changes.
Frequently Asked Questions
- What does a sway control kit do for an RV? It reduces trailer sway by increasing resistance to sideways motion, helping stabilize steering and braking.
- Can I add sway control to my existing hitch? Many sway control kits are designed to retrofit with standard weight-distribution hitches, but check compatibility with your shank and ball specs.
- Is lubrication important for weight-distribution hitches? Yes, continuous lubrication helps keep spring bars functioning smoothly and reduces wear.
- What should I consider when choosing between a standalone kit and a WD hitch with sway control? WD hitches provide weight distribution plus sway control in one unit; standalone kits offer flexibility to upgrade existing hitches.
- How do I know the right capacity for my trailer? Match the GTW and TW ratings of the hitch system to your trailer’s gross weight and tongue weight for safe operation.
- Are taller sway bars better for larger RVs? Not necessarily; effectiveness depends on geometry, weight distribution, and installation quality, not just bar height.
