Andersen Hitch for Lightweights

I don't know how much weight restoration my Durango requires, or if Dodge's recommendation is based on fender height, not weight, as some are.---

I've never been able to find out what Dodge recommends for front axle load restoration.
However, there effectively is no difference between a height-based requirement or a weight-based requirement.
The amount of load transfer required to return the front axle to the unhitched height is effectively the same as the amount of load required to return the front axle to the unhitched weight.
Height measurements are a less accurate means of determining load transfer due to hysteresis effects in the front suspension components.

---My interest in 100% or 50% was to get an idea of how well it performs, compared to others.

Has anyone done similar analysis of spring bar type WDHs?

It has been demonstrated many times that the "conventional" WDHs can generate in excess of 100% FALR, although that no longer is considered as desirable as it was in years past.

With a conventional WDH and relatively light TWs, if your existing WDH setup cannot generate 100% FALR, you usually have the option of increasing the load transfer by switching to higher-rated WD bars.

The load transfer capacity of the Andersen WDH is limited by the polyurethane bushings and, AFAIK, there is only one strength of bushing available.
