CURT 17063 Round Bar Weight Distribution Hitch with Integrated Lubrication and Sway Control
This weight distribution hitch provides level towing by spreading tongue weight across the vehicle and trailer. It includes a trailer sway control bar and an integrated lubrication system with two grease zerks for continuous lubrication, promoting quiet, smooth operation. Constructed with a forged steel spring bar design, it supports heavy loads and offers reliable strength for towing up to 14,000 lbs gross vehicle weight and 1,400 lbs tongue weight.
VEVOR Sway Control Weight Distribution Hitch, 1,500 lbs Capacity
VEVOR’s system emphasizes all-weather structural integrity with a forged high-tensile alloy steel frame. It features a Four-Way Dynamic Stability System to neutralize inertia from multiple directions, helping prevent sway during turns and lane changes. The weight distribution mechanism redistributes load across the vehicle and trailer axles, reducing bumper pressure and improving braking response for safer, steadier towing.
CURT 17200 Trailer Anti-Sway Bar Control Kit
This sway control kit improves trailer handling by applying brake pad-type material to restrict lateral trailer movement. It is compatible with a wide range of CURT weight distribution hitches and many A-frame trailers. It is highly adjustable, allowing users to fine-tune sway restriction through a simple hex nut toggle. This flexibility helps tailor sway control to different trailer sizes and payloads.
BulletProof Hitches Trailer Anti Sway Control System
BulletProof Hitches offers a sway control kit designed to connect the hitch’s sway control ball mount to the trailer front, reducing sway for smoother towing. It is recommended for trailers up to 10,000 lbs with limitations on surge-brake setups. For longer trailers or heavier loads, multiple sway control systems may be required, and compatibility with BulletProof hitches and dual ball configurations is noted.
CURT 51202 True Course Advanced Bluetooth Trailer Sway Control System
True Course uses motion-detecting technology and a microprocessor to detect trailer movements outside normal ranges and quickly apply trailer brakes to prevent sway. It bypasses the brake controller in emergencies for rapid response and independent sway control. This system works alongside your weight distribution setup to enhance stability and limit sway through precise, automatic braking interventions.
CURT 17500 TruTrack 4P Weight Distribution Hitch with Sway Control
The TruTrack 4P system actively resists trailer sway at four distinct points using a cam and spring mechanism. It provides precise weight distribution and four-point sway control for a smoother, safer tow. Setup and adjustment are designed to be straightforward, with a tilting head and adjustable shank compatible with a 2-inch receiver. This configuration supports efficient, customizable stabilization for various trailer configurations.
CURT 17601 TruTrack 2P WDH with Sway Control
The TruTrack 2P system focuses on precise weight distribution and integrated sway control. It uses round spring bars and a highly adjustable 7-hole shank to fit a 2-inch receiver. The tilting head design allows easy adjustment without fully disassembling the hitch, helping maintain proper alignment as loads change. The result is a stable towing experience with reduced sway and balanced weight distribution.
Buying Guide
When selecting a sway control system or weight distribution hitch, consider the following factors:
- Weight and tongue weight capacity: Ensure the hitch is rated for your trailer’s gross weight and tongue weight. A mismatch can reduce effectiveness or cause wear.
- Type of sway control: Active vs. passive systems offer different response times and tuning. Active systems (cam/spring, or electronic braking) generally provide stronger sway rejection.
- Coupling compatibility: Confirm compatibility with your existing hitch, receiver size (2-inch is common), and whether you need a single- or multi-point sway control setup.
- Lubrication and maintenance: Some models include integrated lubrication for smoother operation; check ease of access to grease fittings and servicing needs.
- Installation and setup: Some designs emphasize quick setup and tilting heads for easier adjustment. Consider how often you’ll change trailers or payloads.
- Additional safety features: Bluetooth-enabled systems or motion-detection technologies can offer real-time monitoring and proactive sway management, but verify reliability and compatibility with your vehicle.
- Long-term durability: Look for forged steel construction, corrosion resistance, and proven performance in varying weather conditions.
- Warranty and support: A strong warranty and accessible customer support can help with adjustments and replacements over time.
In practice, most buyers should match a sway control system to their trailer type, overall weight, and towing environment. For frequent long hauls and high wind or crosswind conditions, a system combining weight distribution with active sway control tends to deliver the most stability. For lighter trailers, a proven sway control kit integrated with a reliable hitch head may suffice.
