Henry,
I'm not sure what you mean by unsafe. I don't think that using heavier springs would impose any driving or handling hazards per se.
Springs which are too strong will definitely impose greater stresses on the trailer, the hitch assemblies, and the tow vehicle's frame or unibody structure. This would be especially true when you crossed a low point such as when crossing a low gutter as you enter a driveway approach.
Someone had been running 1,000 lb bars on our
Casita with an Eaz-Lift WDH. That was far too strong as we ran a maximum of about 400 lbs tongue weight on the Casita. I looked into lighter bars; 600 lb bars were available. Ultimately, I just never used the WDH as the Audi handled the trailer so well without one.
I've pondered using a WDH with the
Escape 21 on our JGC. As we have been running between 500 to 550 lbs on the tongue weight I've looked into hitches with bars rated on the order of 400 lbs to reduce the stresses, realizing that this would in turn reduce the amount of weight transfer achieved.
Jeep calls for using a WDH when the tongue weight exceeds 500 lbs. The maximum tow ratings are 720 / 7,200. We don't have substantial "squat". We are currently well within our towing, payload,
axle and gross weight ratings. So, I figure that using 400 lb bars might be satisfactory in our case.
While the idea of using springs with a lower rating is just a bit of theorizing on my part, I do think that using overly-heavy springs would impose some excess stresses.
