Frequently Asked Questions
Will this regulator fit my Softail?
Yes — this part is designed for 2008-2010 Softail models. Verify your year before ordering.
What does this regulator do?
It manages your charging system output and prevents battery overcharge. A failed regulator can damage the battery or electrical system.
How is this cooler than OEM?
The SCR circuit and surface-mount board design dissipate heat more efficiently than standard designs, keeping operating temps lower.
Is installation difficult?
Regulators are typically bolted in place — a basic job for most riders or a shop. Disconnect the battery before beginning.

Voltage Regulator Replacement
Straight forward installation though confusing at first. Apparently my 2013 was retrofitted with an earlier version VR with the old style connections. Your graphics online helped to ensure I had a positive fit without having to mcgyver the electrical connections. Very happy with the service and the product, but most especially the price!
