Preemptive in that I’m prepping for 37s . Since shop will be doing regear .. figured I’d do shafts as well. I’m leaning towards doing it now
Unless you're upgrading your shafts to 35 spline, I personally would save your money until you actually need to upgrade. I think you'll find that the factory shafts do pretty well and especially so in the rear. Of course, if you're getting new lockers with your regear, I could totally see how you'd want to bump up to 35 spline.
