We chose Strange's Pro Race (Hy-Tuf) lightweight 40-spline gun-drilled axles. Once again, we wanted bulletproof, and we got it. While this is one tough unit, it is not suggested for daily street driving due to the axleshaft's thickness. Plus, a thinner axle bearing is utilized and is not sufficient for the extreme side loads applied during the vigors of street driving. Since our Monte will see limited street time, we didn't figure this was an issue (remember give and take?).
