Weight distribution hitch or helper bags/springs?

[Beentheredonethat]

I have a new mechanic I asked about a WDH for the back end of my Suburban. He said that would work fine or heavy springs/bags. The springs would be more expensive.

Any feedback on this? The trailer is a 4 horse stock with a open tongue, so I guess fairly easy to put on a WDH.

Here is a page about springs I found: http://www.fourwheeler.com/how-to/suspension-brakes/129-1306-stop-the-squat-towing-suspension-upgrades/

On this RV forum, the guy says the springs don’t do the job as well:

Helper springs and WDH do completely different things! You may even need both, depending on the tongue weight you’re dealing with. Helper springs help support the weight on that one axil. WDH helps shift weight from the back axil to the front axil for better balance and control.

Ah, so maybe getting both is a good idea?

Depends upon multiple factors, such as if you have factory towing (desirable) and the nature of your trailer load including length, weight and tongue weight. While I’m perfectly comfortable with towing with an SUV (and I do), IMHO, a 4-horse may be pushing things, although at least a stock is often a little lighter than other formats. A WDH is a no-brainer requirement. The springs are more about the capacity and condition of your rear suspension.

I had air bags installed in my 3/4 ton Dodge Diesel after I got a bigger heavier 2H LQ trailer (11’ short wall). When normally driving, you leave 10#'s of air in them, but when I’m going to pull the trailer, I use a small air compressor (plug into truck) and fill them to 40#. It makes a big difference in the back of the truck and keeps everything level.
