Question on diff drop

[Superspirit]

I've been reading and trying to figure out. At what lift is the differential drop a good idea. My truck has right at a 3" lift. Wondering if I need to drop the diff?

I kept struggling with turning my driver’s side cv axles into junk. I had a 2.5” level in the front (spacer on top of the strut, not my idea, was there when I bought it) but I had always heard that 3.5” is the magic number where you should begin to evaluate whether a diff drop is helpful. Since I was under that height and still chewing through axles, decided to put in the Peak Suspension 1” diff drop, mostly because out of all the options that was the one that felt the easiest to back out of if I needed to bring the diff back to stock position for any reason. The 1” drop improved my cv axle angle by about 4 degrees.

I would try and evaluate your situation by looking at it through the lens of your cv axle angle and whether a drop is needed to mitigate your particular angle. It varies from truck to truck because of different factors, like wheels, tires, type of level, etc. So it’s not as simple as having a magic number of “x” but more about what your current angle is and whether that needs to be improved.

I also ended up replacing my front assemblies to Icon 2.5’s and have them at max height of 3.5” which I’m able to do because of the improved geometry of removing the top hat spacer. My angles are now in a good spot because of this upgrade and perhaps my diff drop as well.
