These are the same pulley's we use on all of our alternators. These are not meant for replacement pulley's on factory or different brand alternators. We only guarantee fitment on Mechman branded alternators.

Please use the technical drawings on the pulleys to verify fitment. Using these pulley's on non-Mechman alternators can result in poor thread engagement, belt alignment issues and even loss of pulley due to incorrect rotor shaft diameters.
