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.

Unique Features of Reese Strait-Line Weight Distribution
The easy-to-use, block-style washer on the Reese system makes adjusting the tilt of the weight-distribution head a snap. This uniquely shaped washer can be rotated and positioned between blocks on the weight-distribution head for simple, secure positioning. And the numbered sides provide reference points should you need to adjust your system between different tow vehicles. This is a huge improvement over the standard pin-and-washer method, which involves piling washers - one on top of another - onto a difficult-to-access pin to obtain the desired tilt.
The round spring bars of this system slide up into the weight-distribution head and secure with pins for quick, easy installation. With a tapered design and hot rolled steel construction, these bars offer superior flex, ensuring a smooth, controlled ride for both your tow vehicle and your trailer. In addition, these specially designed bars have rounded, hooked ends, making them the only kind of spring bars that can function with Reese's active-style, dual-cam sway control.

Dual-Cam Sway Control
Reese's dual-cam sway-control system stops trailer sway before it begins. This is a significant improvement over traditional friction-style controls, which help to correct sway only after it has already begun. This specially designed system uses unique sliding devices called "cams" to suspend the spring bars of your weight-distribution system. One end of a cam bolts onto your trailer's frame, and the other end attaches to the lift bracket via the lift chain. The rounded, hooked ends of the spring bars then sit in these cams. The controlled placement of the spring bars keeps your system secure while still allowing enough movement for free, easy interaction between your trailer and your tow vehicle.

During basic, straight-line towing, the cams lock in place and hold the trailer steady by applying constant, consistent pressure to both sides. This keeps the trailer from swaying in crosswinds. When you go into a turn, the cams unlock and slide to allow a controlled, full-radius maneuver. If you swerve suddenly, the cams will give to accommodate the movement while still working to obtain a straight angle, thereby maintaining control of the trailer.

- Weight Distribution Recommendation for 19 Foot Airstream Trailer with 400 lb Tongue Weight
- Keep in mind that when determining tongue weight you will also have to include the weight of anything loaded behind the rear axle of the tow vehicle, as well as any gear stowed in the Airstream. We refer to this as the as-towed tongue weight of the trailer.
Ideally, you want the as-towed tongue weight of the trailer to fall right in the middle of the effective range of the weight distribution system you choose. The RP66086 has a effective range of 200-600 lbs, while the range of the RP66087 i

- How do Hitch Adapters and Extenders Reduce Hitch Weight Capacities
- Using an additional extender, like part # HE12, is very different than the rack, like part # SMC600, having a lengthy shank.
The extenders like part # HE12 are usually made of two different sized pieces of steel that are welded together. The HE12 uses a 2x2 outer dimension piece of solid steel that inserts into the hitch. Welded to the other end, is a piece of tube with a 2x2 inside dimension. That joint is a weak spot. This is a large part of why most of the extenders have a 50 percent weigh

- Weight Distribution/Sway Control Recommendation for a 38 Foot Monaco RV Towing an Enclosed Trailer
- Since RVs usually have a larger section of the body behind the rear axle as compared to a passenger vehicle, you could experience a rougher ride, trailer sway, or RV sag, so weight distribution would be a good idea in this situation.
I recommend a system that has built in sway control. Since you will be towing an enclosed trailer, the large flat sides of it will catch a lot of the wind from passing big rigs, and cross winds blowing across the highway. You will need a system that has a tongue

In this case, the tongue weight of the trailer would be as little as 350 pounds, unloaded, or as much as 1,080 pounds when loaded. The system you have referenced, # RP66087, is rated for 400 to 800 pounds tongue weight. It would be better to go to the next step up, 600 to 1,200 pounds to better encompass the tongue weight range.

- Which Sway Control System is Best for a 23 Foot Trailer
- Which sway control product you should choose depends on the degree of sway you are experiencing.
If the sway you are experiencing is relatively minor, going with a friction-type sway control like part # 83660 might be a good choice for you. A friction device helps resist sway after it starts. Keep in mind that a friction type system must be removed when backing up, or when roads are slippery.
If the sway is more severe, the dual cam system like part # RP26002 would be ideal for your need

- Weight Distribution System for Starcraft 3600 lb Hybrid Travel Trailer Towed by 2009 Nissan Xterra
- The severity of trailer sway can vary from an annoying condition to one that is downright frightening. Ensuring that your trailer is properly loaded is the first step to combating trailer sway. Your trailer should be loaded so that its tongue weight (downward force exerted on the trailer ball) is 10 to 15 percent of the weight of the fully-loaded trailer. If the tongue weight figure is less than 10 percent, adding more weight to the front of the trailer can diminish the sway.

- The difference between the Reese round bar Strait-Line weight distribution system # RP66087 and the trunnion bar version, part # RP66083, is going to be ground clearance. The round bars hang down lower, so trunnion bars are a better option for low vehicles such as minivans. You should not have a ground clearance issue with your 2006 Chevrolet Silverado.
There used to be a more noticeable difference in weight capacity between the two bar styles years ago, but designs have changed to a point
