I see a lot of discussion on Trailer hitches and
weight Distribution. and Sway control I run across this and it looks like pretty good information for someone who is new to towing.
Weight Distribution Trailer Hitch Systems
Weight Distributing Hitch Systems are designed to increase the capacity of the towing system when added to a Class III, IV or V trailer hitch. The idea is to distribute the load of the trailer evenly to all of the tow vehicle and trailer wheels. To accomplish this, spring bars are used to absorb load and level the trailer. This offers a more level ride, improved steering and increased braking control, all the while enhancing towing safety.
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, larger trailers with greater TWs can be towed with more ease. The weight distribution systems listed on this website can pull a maximum gross trailer weight (GTW) of 4,000, 10,000, or 12,000 lbs, but this may exceed the vehicle's or the hitch’s maximum towing capacity. To find the vehicle specifications refer to its operation manual.
Note: For safety, make sure your tow vehicle is capable of towing the intended trailer or accessory. The trailer or accessory and the vehicle work together in determining the maximum capacity. In no case should the GTW or TW exceed the towing capacity of your vehicle, your trailer or your accessory.
A weight distributing system includes a receiver or hitch attached to the tow vehicle, a hitch head mounted on a shank that fits into the receiver opening, a spring bar assembly that fits into the hitch head, and hook-up brackets that connect the other end of the spring bars to the trailer frame with chain.
A very popular option that often becomes part of the weight distributing system is the Sway Control. A sway control is particularly useful for longer trailers or for those with a large surface area. The addition of a friction or dual cam sway control dampens sway caused by traffic and crosswinds and contributes positively to tow vehicle and trailer stability. The weight distributing system’s hitch head comes sway control ready.
Note: AIR SPRINGS, AIR SHOCKS, and OVERLOAD SPRINGS are devices that help the tow vehicle’s rear suspension support trailer tongue weight as well as the weight of passengers and luggage. They are particularly useful on “soft-sprung” vehicles or those whose springs have settled. However, they are not substitutes for weight distributing hitches, for they do not re-distribute load to other axles.
