2 Steps for Finding the Right Weight Distribution Hitch Size

For the best ride, you'll need a weight distribution hitch designed for your trailer's tongue weight. If you choose a WDH that is too light for your application, the hitch won't be effective. If you go too heavy, however, you'll suffer a rigid ride and a bouncy trailer.So how do you find that Goldilocks weight distribution hitch that's just right? Check out our video how-to, or read on below for a step-by-step explanation on finding the right weight distribution hitch size.

Example Part I:
Let's say our trailer tongue weight is 700 lbs and our cargo behind the rear axle is 200 lbs. Our total tongue weight is 900 lbs.

Step 1. Determine Your Total Tongue Weight

First, you need to figure out your loaded trailer tongue weight (TW). Your tongue weight is the downward force you're putting on the ball of the weight distribution setup with your loaded trailer, plus the weight of any gear behind the rear axle of your vehicle.Note that this is not the dry (unloaded) weight listed on your trailer spec sheet, but rather the fully loaded, ready-to-tow weight after you've packed in all the gear you want to carry.To determine your trailer tongue weight, you can use a scale like the etrailer tongue weight scale. You can also use one of the other methods outlined in our help article, Determining Trailer Tongue Weight.Also add in the weight of any cargo (gear, coolers, luggage, etc.) you've added behind your rear axle.This sum will be the total tongue weight you have to work with.

Step 2. Select a System with the Right Weight Capacity

We've broken out our weight distribution hitches by tongue weight on our website for your convenience. Once you have your tongue weight figure, simply select your TW from the list and choose a system.
Pro tip: It's best that your total tongue weight (sum of your trailer tongue weight and cargo) falls in the middle of your WDH range. This gives you a bit of wiggle room if your tongue weight varies between trips.For example, if your total tongue weight is about 1,000 lbs, a weight distribution hitch with a tongue weight rating of 800 - 1,200 lbs is ideal.

What if you're pulling multiple different trailers and they all have different tongue weights, GVWR's, etc.? Do you go with the hitch that will have the highest weight rating you may encounter?

@Elden Ideally you still always want your loaded tongue weights to be in the middle range of the capacity of the hitch. So in the case where there's multiple trailers, you can either get a couple different hitches (not ideal), or go with one that has the widest possible range of tongue weight capacity. For example, the Strait-Line Weight Distribution # RP66084 is for loaded tongue weights between 600 lbs and 1,200 lbs, or the B&W Continuum Weight Distribution # BW78FR is for loaded tongue weights between 600 lbs and 1,600 lbs.

Looking for WDH for a 2018 Explorer XLT pulling a 20 foot car hauler loaded with ATVs. Trailer weight is approximately 4000 pounds. My confusion comes from the fact that the trailer has a 7000 pound gross. Should the WDH be rated for the trailer gross or the weight of the trailer as loaded?

When determining tongue weight must you include the additional weight of the Weight Distribution Hitch itself? A WDH easily adds 100 pounds to your tongue weight and could definitely cause you to exceed the tongue weight rating of your vehicle’s hitch. Let’s say your vehicle is rated at a max tongue weight of 500 pounds and your trailer’s tongue weight is 450 pounds then you will exceed the limit by 50 pounds with a WDH installed.

Hi new this this travel trailer stuff, looking for weight distribution hitch for: Trailer Dry 5975 GVWR 10872 hitch weight 712, Thanks!

@Christina For your trailer with a GVWR of 10,872 lbs I recommend the 16K Equal-i-zer Weight Distribution System w/ 4-Point Sway Control # EQ64FR. The 16K rating sounds like too much but we actually base the weight distribution system rating off of the loaded tongue weight instead of just the weight of the trailer. The 1,200 lbs - 1,600 lbs tongue weight range for this system is perfect for your trailer.

@David If the fully loaded and ready to tow tongue weight of the trailer (including the weight of anything in the truck bed behind the rear axle) is greater than 1000 lbs, you'll want to upgrade to the next highest rated spring bars, # BXW4008. If you're 1000 lbs or below, you're good go to with your current setup. Hope that helps!
