Weight Distributing Hitch

Create a stable ride for your tow vehicle and trailer with a weight distribution hitch. Adding spring bars to your towing system applies leverage, which transfers the load that is pushing down on the rear of your vehicle to all the axles on both your tow vehicle and your trailer, resulting in an even distribution of weight throughout. The result is a smooth, level ride, as well as the ability to tow the maximum capacity of your hitch.



Selecting a Weight Distribution System

The tongue weight rating is the most important factor in determining which size weight distribution system you should use. If the bars of the system you choose are rated too high for your setup, they will create a rigid ride, which can result in a bouncing trailer. If, on the other hand, the bars are not rated high enough, the system will be unable to properly distribute the weight, rendering it virtually useless.


To determine the proper weight rating for a weight distribution system, you must first determine your trailer's tongue weight. Then add to that the weight of the cargo behind the rear axle of your tow vehicle. These two measurements make up the tongue weight rating for a weight distribution system.


Integrated Dependent Sway Control

The Steadi-Flex weight distribution system works to stop trailer sway before it begins. This is achieved in 2 ways. First, the system head is designed to firmly hold the spring bars in place to provide tight resistance and help ensure that your trailer tracks behind your vehicle. Second, the spring bar brackets that mount on your trailer's frame produce friction with the bars whenever any side-to-side motion occurs. This keeps the bars from moving, also helping to hold your trailer in a straight line.


System Head with Steel-on-Steel Friction

System Head

The head of the Steadi-Flex system firmly holds the spring bars in place at the hitch point. This tight hold helps to keep the bars from moving, which in turn helps to ensure that the trailer is held firmly in place behind your vehicle. If any sway or side-to-side movement does occur, the spring bars will move only slightly inside of the system's head. This steel-on-steel contact produces frictional resistance to limit further side-to-side motion of the bars, limiting the motion of your trailer in the process. The Steadi-Flex head is wider than most weight distribution heads. This design allows for greater surface area for the spring bars to move against. This makes it easier to produce the friction that resists sway.


Sway Control Brackets with Automotive-Grade Friction Material

Friction Material Brackets

The spring bars attach to the trailer frame with fixed, sturdy steel brackets. They sit on top of the brackets instead of being suspended by chains like the bars that are on traditional weight distribution systems. Chain suspensions typically allow a good deal of side-to-side play in the system. Because the Steadi-Flex has brackets in place of chains, that unwanted movement of the spring bars is eliminated. This helps to keep your trailer in line behind your vehicle. In addition, these brackets create friction to limit any side-to-side movement that may occur. When each spring bar on the Steadi-Flex system moves within the bracket, it rubs along the surface of the bracket, creating friction. This resistance limits the movement of the spring bar, thus preventing further side-to-side movement of the trailer.


Friction Material

Most systems with sway control brackets use bare steel brackets to create friction with the steel bars. Steel-on-steel friction typically causes a much louder ride, and it can result in wear and tear on the brackets themselves. The Steadi-Flex brackets, on the other hand, are lined with automotive-grade friction material. This material is more abrasive than bare steel, which allows more friction to build up faster and easier. The long-lasting friction material also reduces the banging noise created by the bars hitting the inside of the steel brackets. This provides a quieter ride while towing.


Fast, Easy Installation

The Steadi-Flex system is easy to install and set up. On the trailer side, simply clamp the spring bar brackets around your trailer's frame. Then prepare your vehicle by sliding the included shank into your 2" x 2" hitch receiver, and bolt on the head. The system head can be easily adjusted to achieve the proper angle and optimum leverage for your specific setup. No drilling is required to install this weight distribution system.


Head Tilt Adjustment

Head Adjustment

The head of the Steadi-Flex can be easily adjusted for the best possible angle for your towing setup. Adjusting the head lets you fine-tune the system's leverage so that you can get the best distribution of weight possible. Traditional head tilt adjustment methods require that the head be disassembled so that stackable washers inside the head can be either removed or added on. But with the Steadi-Flex, there are external, toothed washers on either side of the head that make it easy to change the tilt. Simply position the head in one of the preset angles based on your hitch's tongue weight, then bolt it in place, tightening the washers as you do so. Once the head is sitting at the correct angle, tighten the internal adjustment bolt to secure the platform in place.


Tapered Spring Bars

Spring Bars

The spring bars of the Steadi-Flex system slide into the weight distribution head for quick, easy installation. With a tapered design and hot rolled steel construction, these bars offer superior flex to evenly distribute the weight between your tow vehicle and your trailer.


The bars easily pin into place inside the system head - no need to torque or re-torque any trunnion bolts to adjust the tension. With fewer parts to manage, installing and maintaining the Steadi-Flex is simple.


Adjustable, Clamp-On Brackets

The spring bar brackets simply clamp around your trailer's frame - no drilling required. These brackets are designed to be positioned 27" to 32" back from your coupler and they can fit a wide range of frame sizes and can even be used on a trailer with a bottom-mounted coupler.


Adjustable Brackets

While other brackets use L-pins to secure the spring bars in place on the brackets, the hinged Steadi-Flex brackets close completely around the spring bars. As a result, you can have greater piece of mind knowing that the spring bars are secure, all without the hassle of using and possibly losing L-pins and any extra hardware.

  • Replacement Friction Pads for the Reese Stedi-Flex Weight Distribution System
    The Reese Steadi-Flex Weight Distribution System w/ Sway Control - Trunnion - 10K GTW, 1K TW # RP66559 utilizes friction pads that will eventually wear down as you stated. It will take a long time for these pads to require replacing, but the Replacement Friction Pad Kit for Reese Steadi-Flex Weight Distribution Systems # RP58527 are available and easy to replace with a simple screw and nut.

  • Is It Okay To Use the Reese 12K Steadi-Flex On a Trailer Under 12K
    Yes, you can use a weight distribution system that is overrated for the trailer you intend to use it with. However, the best performance will come from a system that matches the total tongue weight of your towing setup. In order to find the total tongue weight of your towing setup you will need to calculate the loaded ready to tow tongue weight of the trailer plus the weight of any cargo stored behind the rear axle of the tow vehicle.

  • Weight Distribution and Sway Control for a 2006 Lexus GX470 Towing a Featherlite Open Car Trailer
    I recommend Reese Steadi-Flex Weight Distribution system, part # RP66559, if the tongue weight of your trailer will always be less than 1,000 lbs fully loaded and ready to travel. The Steadi-Flex will help to control sway and will reduce the stress on the vehicle auto-leveling system. You will need a properly sized hitch ball to complete your installation, the compatible hitch balls we offer can be seen at the link below.

  • Solution for Needing Curt TruTrack C17499 with More Drop from Shank
    The Curt TruTrack part # C17499 that you referenced is not available without a shank so you'd need to also go with the shank part # 17120 which would provide the drop you'd need. We also don't carry a similar rated system without a shank but we do have the Reese Steadi Flex part # RP66559 which has a tongue weight range of 500 to 1,000 lbs and comes with a shank that can do 4 inches of drop.

  • Recommended Trailer Hitch Receiver, Wiring, and Weight Distribution for 2013 Nissan Armada 4x4
    For your 2013 Nissan Armada, I recommend the Curt Trailer Hitch Receiver # 13188. This will be able to tow your trailer with 1 horse without weight distribution, but you will most likely need the weight distribution system for 2 or 3 horses. It will also help with sway control, so I would use it no matter the number of horses. For your wiring, if you don't have the factory 7 way, I recommend the Vehicle Wiring Harness Kit with 4 Pole Trailer Connector # C59236 along with the # ETBC7...

  • Should Tongue Weight be Measured When Choosing Weight Distribution
    I definitely recommend finding your trailer's tongue weight when choosing a weight distribution system.

You want a weight distribution system that has a tongue weight range that covers the tongue weight once you have that figured out. The closer to the...

This will give you a gross trailer weight of 8,000 lbs when used with weight distribution, so a weight distribution system would be required.

  • Is Reese Steadi-Flex or Dual Cam II a Better Weight Distribution for a 2023 Forest River Alpha Wolf

  • Will 700 lbs Tongue Weight Work Well with the Reese Steadi-Flex Weight Distribution System
    Ideally you pick a weight distribution system that has a range that your loaded tongue weight falls right into the middle of. Being a little high or a little low in the range really isn't too bad as that is the effective range that was established for the system. The Steadi Flex part # RP66559 has a tongue weight range of 500-1,000 lbs. Your loaded tongue weight of near 700 lbs would be perfect. You would be right in the sweet spot for the system.
