Features to know about

Smooth Backups: Built-In Electric Lockout

Backing up a loaded trailer can be tricky when the brakes keep grabbing. The built-in electric reverse lockout solves that by preventing brake activation when you shift into reverse. It wires right into a 5-pole flat, 6-way round, or 7-pole trailer connector so the solenoid automatically engages as soon as you go into reverse. You can back around tight corners or up ramps without the brakes fighting you.

Heavy Loads Made Easy: 20,000 lbs GTW Capacity

This actuator is built for serious hauling. With a 20,000-lb gross towing weight and 2,000-lb maximum tongue weight, it handles large equipment, boats, or multi-axle setups with confidence. The welded steel body and primed finish add strength that resists bending in jackknife situations and gives you a clean base to paint for extra protection.

Straight-Line Performance: Efficient Roller Design

Inside the housing, a unique roller setup keeps the actuator moving in a straight line when it telescopes. That means less resistance, smoother braking pressure, and steadier control on the road. It’s especially noticeable during heavy stops or downhill grades where jerky motion can wear components faster.

Easy Coupling and Secure Connection: 2-5/16" Drop Coupler

The heavy-duty drop coupler uses a trigger latch with a circle grip that makes hitching quick and simple. Just pull back on the trigger to open the ball socket and drop it onto your 2-5/16" ball. The built-in 4" drop helps line up your trailer height to your tow setup so coupling stays level and secure every time.

Ready to Weld: 3" Channel Mount with Breakaway Kit

Designed for weld-on installation on a straight 3" wide trailer tongue, this actuator comes primed and ready for mounting. Once welded in place, it’s solid and aligned exactly how you want it. A built-in breakaway kit is included to automatically engage the brakes if the trailer ever separates from the tow vehicle, adding another layer of safety for heavy-duty towing.

See what our Experts say about this Dexter Brake Actuator

  • Will the Titan T4750820 Actuator Replace Global Direct Components GDC-120 Without Drilling New Holes
    Since the Titan Zinc-Plated Brake Actuator # T4750820 that you referenced has a weight capacity of 12,500 lbs and a tongue weight capacity of 1,250 lbs it will serve well as a replacement actuator for your application. The mounting holes are spaced differently than what you show which means you will need to drill new holes into your trailer tongue. Your mounting holes are spaced in a straight line where the mounting holes for the Titan actuator form more of an arc. Instead of the Actuator...
