Specs At A Glance

Good To Know

Q: Do I need extra fittings for the hose side? A: The plate provides a 6AN male outlet, so you will need a matching 6AN hose end or adapter for your line. Match the hose size and style to your cooler setup.

Q: Can I reuse the factory cooler lines with this plate? A: This plate is intended for 6AN hose, not the factory quick-connect lines. Plan on running new hose from the plate to your cooler.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
