Anyone have any experience with the Yukon 30 spline 4340 Chromoly axles? Kind of figure while I'm doing gears and a TruTrac, might upgrade axles. Really don't want SCS since they are puck style, don't think my center caps will go back on.
Dual splined, which I think you're referring to as 'puck style,' will be substantially stronger than single splined. Even if their the same material.
I snapped a 30 spline on the first pull after I built my motor, and the other side was twisted pretty bad. Went to 38s and never had a problem
