Dexter 099-075-20 Dx7.5 Surge Actuator, Bolt-On Disc Brake, Zinc Plated

The Dexter 099-075-20 is a bolt-on surge actuator built for disc brake trailer axles. As the surge actuator, it is the component that converts the towing coupler's braking force into hydraulic pressure sent to the trailer's disc brake calipers, allowing the trailer to brake in proportion to the tow vehicle's deceleration. This unit uses a bolt-on mounting style rather than a weld-on housing, which allows it to be installed onto an existing coupler or tongue assembly without welding. The housing has a zinc-plated finish, which provides corrosion resistance for the actuator body in the wet, salt-exposed conditions typical of trailer towing and marine/boat trailer use.

The actuator measures 14.5 inches long, with mounting holes positioned 1 inch down from the top edge, allowing for direct alignment on compatible coupler or tongue hardware using this hole spacing. It is identified by Dexter part number 099-075-20 and is intended for disc brake surge systems.
