Product Details

The T4809700 is a bolt-on hydraulic surge actuator for trailers equipped with drum brakes. When the tow vehicle slows, trailer momentum compresses the actuator and sends hydraulic pressure to the trailer brakes.

Its zinc-plated steel housing resists corrosion. The adjustable front channel provides three mounting positions for a compatible coupler, lunette ring, or other approved attachment.

Before ordering: Confirm hydraulic drum brakes, trailer capacity, tongue width, mounting dimensions, coupler compatibility, and reverse-operation requirements.

Features

12,500 lb Capacity

Rated for trailers up to 12,500 lbs GTW with a maximum tongue weight of 1,250 lbs.

Hydraulic Surge Operation

Applies hydraulic drum brakes automatically as trailer momentum compresses the actuator.

Adjustable Front Channel

Provides three mounting positions for a compatible coupler or attachment.

Roller-Guided Movement

Supports straight telescoping movement while reducing internal resistance.

Zinc-Plated Steel

Helps protect the actuator housing against rust and corrosion.

Bolt-On Installation
