Equalizer Hitch

Hoping someone can get my head straight on this: When you tighten up your torsion bars e.g. one link, what does that do to the load? Does it disperse more weight to the rear? Does it raise the rear end of the TV? A bit of insight into the principle would be appreciated.

A Weight-Distributing Hitch System is composed of four major elements:
1) the hitch receiver,
2) the ball mount,
3) the spring bar assembly and,
4) the sway control.
They work in unison to provide complete towing system compatibility.
Operation of Weight-Distributing Hitches
Adjustment is simple because of the
easy-to-operate snap-up brackets that allow spring bar tension to be adjusted by changing links in the support chains. This lets you adjust for various trailer tongue weights within the spring bar weight range by applying tension on the spring bars until the car or tow vehicle is level. Rather than merely supporting the trailer tongue weight (TW), weight distributing hitches apply leverage between the towing vehicle and trailer causing the TW to be carried by all axles of the tow vehicle and trailer. When TW is distributed in this way, trailers with greater TWs can be towed, resulting in a more level ride which reduces stress on the rear of the tow vehicle and provides greater steering and brake control.
Trailer SwayThis must always be considered in trailer towing. Unwanted sway turns a pleasant towing situation sour. Many factors can contribute to trailer sway the design of the trailer, the suspension, tire inflation pressures, configuration of the tow vehicle, towing speeds and hitch weight.
Sway ControlThe Friction Sway Control does exactly what its name implies, it uses friction to resist pivotal movement and thereby works against the effects of included sway. It operates on the principle of "stiffening" the coupling between the tow vehicle and trailer. The degree of "stiffening" or friction is adjusted to suit various trailer weights and towing conditions. Its operation is simple and uncomplicated. It doesn’t prevent the generation of sway; it simply works to resist the forces once they have started.

Equalizer Hitch

Thx for the quick reply Fonzie. I am still wondering what the adjustment is as you tighten or loosen the chain links.

tighten - moves weight from rear axle of tow vehicle to the front axle and to a lesser extent the trailer axles axles.

A weight distributing hitch is set up correctly when the front axle carries approx the same load hitched or unhitched. You are not actually transferring any tongue weight to the front axle at all if set up correctly.

When you put a load (TW) on the rear of the truck, there will be weight removed from the front axle as well. The WDH will put this weight back onto the front axle and also shift 20-25% of the TW to the trailer axles leaving 75-80% on the rear axle of the truck.

Example. Say you have a 1000lb TW and 400lbs comes off the front axle so the actual increase in the rear axle load is 1400lbs. The WDH moves the 400 lbs back the front axle and 200-250 to the trailer axles leaving 750-800 on the rear axle of the truck.

by the way, if your wdh has chain links, it's not an Equalizer hitch.
the Equalizer brand hitch systems uses solid bars with a L bracket and there are no chains.

sometimes dealers will call a basic wdh system, an "equalizer" when that is actually a brand name.

equalizer hitch....NOT

Hey Bikendan,

Thx. My hitch is a Reese Weight Distribution hitch, and it does have chain links. Our Rockwood 2304s has a heavy tongue weight (almost 700 lbs). It tows quite well on the third link, but using the fourth link may help ease the tongue. I realize I need 10% of the trailer weight on the hitch. I will experinment to see which is better, #3 or #4. My installer recommended #4 link. It hauled find there, but it seemed there was an awful lot of tension on the bars. When I backed it off to #3, the tension let up just a bit.

Are you referring to chain lengths that are not used, or the used 1s ???

if you are referring to chain lengths used, most Reese information that I have seen require that at least 5 links of chain be used. If you are referring to lengths left over, than those figures would be OK as long as you are using 5 lengths.

Hitch

Initially, my installer used the link four in from the end of the chain. That's when I felt it was a bit snug, so I have slacking off, using the chain three in from the end. I was not aware Reese wanted five links left over. I have towed quite a few miles at the "3" position. No roughness, no jerkiness, no sway. Because I felt I should ease a bit of the weight off the hitch, I thought I would try it at the "4" link. That is four from the end of the chain.

Reese does not want 5 lengths left over.....they want at least 5 lengths under stress. That would be measured from the end of your spring bar/dual cam to the snap up bracket. How many lengths of loose chain does not matter, and would depend on how long the chain is that came with your setup.

In my setup, I have used 5 links (minimum suggested) and have 3 loss links.

If you have the same 8 length setup, the 3 lengths left over will give you minimum of 5 lengths used. If you have 4 lengths of loose chain, then you only have 4 lengths of chain under stress, which is not enough according to Reese.
