Today we are going to take a look at a Reese weight distribution part number RP66155. This is very common when towing larger sized trailers. What a weight distribution system does is pull down on the front end of the frame of the trailer to help level out the whole towing weight. What it does is it shifts weight forward on the frame of the vehicle to balance out the load, so that the front axle of the vehicle is bearing more weight than it would without the weight distribution system. 0:25
Along the front end of the trailer frame is the spring bars. These spring bars pull the load downward on the trailer frame which helps lift the rear end of the vehicle up and level the whole system out. At the end of the spring bar, you will have some sort of bracket system. This particular kit includes a sway control system. We have our bracket set up and it clamps to the side of the trailer frame, the spring bars sit inside this housing and it is just a cover that goes over the top. 0:53
Inside this trade that the spring bar sits are pads. They are very similar to the brake pads on the vehicle. What these pads do is provide friction resistance. So, if the trailer starts to sway back and forth the friction applied from these pads to the spring bar will help keep the sway under control and correct it. Alright, now we are going to take this set up out on the road so you can see the weight distribution system in action.
Today we are going to cover a few questions about weight distribution in general that we get a lot. First we will start off with the hitch itself. A common question is can any hitch be used with the weight distribution assembly. Virtually any two inch receiver hitch as the one we have here, can accommodate weight distribution. However there are a few odd ones out there that do not, mainly they are on small SUVs and maybe a couple of minivans, for the most part almost any two inch receiver hitch can accommodate weight distribution. The only real bulletproof way to find out is to look at the sticker on the hitch itself and you will see some numbers on there. The numbers you want to look for here are right here. This one says weight carrying and that is for the hitch itself which means that is the maximum weight the hitch can carry without any assistance.
Today were going to show you how to measure for a weight distribution shank. It looks kind of confusing with the different lengths and amount of holes on it and different measurements. Were going to keep it basic and simple so you can pick out the right one the first time and well show the steps that are needed to do that. First thing we do is get two measurements, we need to measure from the bottom of the coupler down to the ground. Also we need to measure from the top of the hitch opening down to the ground. The difference between the two measurements will tell us what size shank to get. Well make that 13 1/2 inches and looks like we have a measurement of 21 inches. With some simple math, the difference will be 7 1/2 inches, so we need to find a that is close to that. The closest one we have is part # 3344. That part will have a eight inch total so that will be as close as we can get. Well check that out to make sure it works. With our measurements in hand, lets go ahead and test it. As you can see the ball height is the same as the coupler so it looks like a perfect match.
