Common questions

What does 'endless' mean for a primary chain?

An endless primary chain is a continuous loop without a master link. This design offers increased strength and durability compared to chains with master links, but typically requires clutch basket removal for installation.

Is this primary chain a direct replacement for my Harley Dyna or Softail?

This Harddrive primary chain is a direct replacement for OE# 40036-06. Please confirm this part number matches your bike's original primary chain specification before ordering to ensure correct fitment.

Do I need special tools to install an endless primary chain?

Installing an endless primary chain usually requires disassembling the primary drive, including removing the clutch basket, as there is no master link to split the chain. Consult your service manual or a professional for proper installation.
