Dexter DX20EX Clevis Hitch 20K Surge Brake Actuator | Weld-On Center Mount for Drum Brakes

Heavy-duty Dexter DX20EX hydraulic surge brake actuator with clevis hitch attachment for 20,000 lb trailer drum brake applications. Built for weld-on center-mount installation with an adjustable channel and emergency breakaway assembly.

Part Number: D068-078-00 20,000 lb GTW Drum Brake Systems

Overview

The Dexter DX20EX clevis hitch surge brake actuator is designed for heavy-duty trailer hydraulic drum brake systems where a weld-on center-mount actuator and clevis-style hitch connection are required. This assembly combines the DX20EX actuator body, adjustable channel, mounted clevis hitch attachment, master cylinder, and emergency breakaway cable assembly into one service-ready replacement solution.

R&P Service Insight

Surge brake actuators are high-load components that control braking force every time the tow vehicle slows. Matching the actuator style, brake type, and hitch connection is critical before replacement.

  • Brake System Match: This listing is for drum brake systems, not disc brake systems.
  • Hitch Style: This version includes a clevis hitch attachment mounted in the adjustable channel.
  • Mounting Check: Weld-on center-mount installation should be performed by a qualified installer.

R&P Knowledge Hub

Compatibility: Designed for hydraulic drum brake trailer systems using a 20,000 lb rated surge actuator and clevis-style hitch connection.

Vehicle / System Fit: Commonly used on heavy-duty equipment, utility, flatbed, and industrial trailers equipped with hydraulic drum brakes.

Installation Notes: Verify trailer tongue configuration, weld-on mounting location, brake line connection, clevis hitch requirements, and actuator rating before installation.

Performance Insight: The adjustable channel allows the clevis hitch position to be set for proper trailer height and towing alignment.

Brand & Fitment Note

Selling Brand: Dexter

Application Reference: This listing describes a Dexter DX20EX clevis hitch hydraulic surge actuator for supported hydraulic drum brake trailer applications.

What This Means: This listing is for the Dexter DX20EX actuator assembly with clevis hitch attachment as identified by part number D068-078-00.

Before Ordering: Verify part number, brake type, mounting style, clevis hitch requirements, trailer tongue setup, hydraulic connection, and included components before installation.

R&P Repair Insight

Replacing a surge actuator usually means the original unit has worn internal seals, damaged slide components, corrosion, or poor brake response. Always confirm the brake type and hitch connection before ordering, because drum and disc actuator setups are not the same.

  • Drum vs. Disc: Confirm your trailer uses hydraulic drum brakes before installing this actuator.
  • Clevis Fit Check: Confirm the clevis connection matches your tow setup and pin requirements.
  • Brake Fluid Service: After installation, fill and bleed the hydraulic brake system according to proper brake service procedure.
