I am very interested in replacing my springs with the next load range up because I have some sagging on one side. Mine is double 3,500 lb axles.
I am wondering if stronger springs will increase the chance of bending the axles? I have found a 2,000 and a 2,100 lb spring that will fit in place of my 1750 lb springs with no modifications.
These axles are not famous for being over-designed. It seems like stronger springs would increase the force on the axle when going over a bump, since the springs will resist the bounce more.
Anyone had a problem with bending an axle after (and because of) replacing springs with a stronger spring?
BONUS QUESTION: My current springs are 4 leaf, but the 2 stronger springs mentioned are 3 leaf. Does going from 4 to 3 leaf cause any problems?
