Just curious what DSF you apply to sprung and unsprung members? My trailer design engineer friend (HD, not MD or light) does 3G for frame loads but has no idea what axle and suspension manufacturers design to.

Im not the designer, but typically around 20%.

To yield or UTS?

Huh? No idea what you mean.

Sorry, should have been more specific. 20% of yield strength (i.e. where permanent deformation begins) or 20% of Ultimate Tensile Strength (i.e. where things actually break).

No idea. I run the company, I'm really not involved in the engineering.
