We use our exclusive heat treat process and material combination that we developed over years of research and development.

We are so confident in the shaft we stand behind it with our warranty. If it bends or breaks we replace it. (does not cover wear - if it held up through numerous beatings it did its job well)
These drive shafts are for the diff to the wheel, fit both front and rear.
Sold individually.

All warranty claims for Fast Lane Machine products are handled by Fast Lane Machine directly. Fastlanemachine@sbcglobal.net
