I would not use one if it was given to me.
It makes you go fast but the risks are too great for me. More will fail as time goes by. Heck, even the OEM ones will fail eventually, these after market ones will fail and have failed much sooner.
If you insist on using one, do as advised previously and fit the LM21 scatter shield. I would advise anyone using an after market pulley to use the scatter shield.
The dog bone spring should be made from a steel alloy that has been heat treated so that it is in fact a spring. Many springs are colored by this process, most often blue. I doubt your one is a real spring and is probably just stainless steel. Stainless steels do not make the best springs. The OEM ones are springs and are not blue, they are probably treated against rust.
Only pulleys where the clutch plate returns to the stops when the magnet is switched off have real springs, the rest will fail in a short time.
