For those of you that have the larger units on a diesel pickup, I would assume they add some real weight in front of the front axle. Do you need to up the front spring rates to account for the added weight of the brush guard?
On the GMs with the torsion bar suspension, they would sometimes crank the bars or install a leveling kit.
I have had a Ranch Hand on a 93 Ford diesel with the IFS. Been fine for 15 years.
