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, serrated washers on the Reese Strait-Line system make adjusting the tilt of the weight-distribution head a snap. 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. The serrated-washer system lets you easily loosen, adjust and tighten a single washer and nut on either side of the head for simple, secure positioning.
The trunnion spring bars of the Strait-Line 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, ensuring a smooth, controlled ride for both your tow vehicle and your trailer. 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.

You need to make this adjustment, if needed, after the the vehicle and trailer are loaded and ready for travel. If you are perfectly level, when fully loaded, and the ride is good with the hitch ball straight up no further adjustments are needed.

- Which Weight Distribution and Sway Control System Should I use on a 1994 Chevy 3500 with Car Trailer
- In order to select the best suited weight distribution system for your setup, you will need to know the total loaded weight of the trailer, the 2,700 pounds for the car, 500 pounds for the golf cart, the weight of anything else in the trailer and the weight of the trailer itself. You would then select a weight distribution system based on this total.

I recommend the Curt Trailer Hitch, # 13367, which is a custom fit item for your 2007 Toyota FJ Cruiser, unless your FJ is equipped with the auxiliary fuel tank. The hitch will bolt to the frame and this one will install in about 30 minutes. I have included a link to the instructions below.

- Adjusting Reese Strait-Line Hitch, # RP66072 to Reduce Trailer Hitch Ball Grating
- Adjusting the ball on the head unit of the Reese Strait-Line Hitch, # RP66072, in order to change the number links in the chains is going to require some trial and error. This is because each vehicle/trailer setup is different and there is not a universal formula for how many notches on the ball adjustment equal how many links on a chain. Most likely several adjustments will need to be made.

- How to Alleviate Sag on the Rear End of a 2005 Ford F-150 Towing a Toy Hauler
- Toy hauler trailers are notorious for having very heavy tongue weights, often up to 15 or 20 percent of the loaded trailer weight. Just because the F-150 itself is not made for very heavy duty loads, you will probably see some sag with whatever you do, but there are some things you can do to relieve some of the pressure on the rear end. I would try moving your load back from the front of the trailer to see if that alleviates some of the sag you are experiencing.

The most notable difference between trunnion and round bar setups is how they attach to the head of the weight distribution system.The round style bars slide up into the head and are held in place with clips. The trunnion style bars slide into the head from the side or back.

Even though a trailer hitch may be rated for use with weight distribution and the rating when using it is higher that still does not allow the vehicle to tow more weight than what it is rated for. You will need to get the tongue weight below the 350 pound limit of the vehicle to safely tow the trailer. You can do this by moving weight towards the back of the trailer if at all possible.
