Load Rite 6,600lb Disc Brake Actuator Tie Down Engineering Model

The 6,600lb Disc Brake Actuator Model 660E by Tie Down Engineering is a robust solution tailored for marine enthusiasts who demand enhanced safety and performance from their boat trailers. Designed to synchronize the braking systems of your trailer with your tow vehicle, this actuator ensures smooth and controlled towing, crucial for the secure transport of your vessel across water bodies.

How the Model 660E Works

The Model 660E utilizes the “surge” or “push” method, which engages when the trailer accelerates forward, pushing against the tow vehicle. This action triggers the actuator to telescope, applying force to the master cylinder and generating hydraulic pressure to activate the trailer's disc brakes in unison with the tow vehicle's axle brakes. The built-in dampening shock absorber moderates the telescoping motion against the hitch ball, reducing vibrations and maintaining stability during towing. This is essential for preventing sway and ensuring safe maneuvering on marine-accessible roads.

Key Features

• High Capacity: Supports a gross load of up to 6,600 lbs., making it ideal for a wide range of boat trailers.
• Universal Compatibility: Fits standard 2″ hitch balls, ensuring easy integration with most tow vehicles.
• Disc Brake System: Specifically engineered for use with disc brakes, providing reliable stopping power in various towing conditions.
• Multiple Tongue Sizes: Compatible with tongue sizes of 3”x3”, 3”x4”, and 3”x5”, accommodating different trailer designs.
• Easy Installation: Fully assembled and ready to bolt into place, simplifying the setup process for boat owners.

Installation Guidelines

Before installing the Model 660E Actuator, thoroughly review your tow vehicle’s owner’s manual to understand the recommended towing capacities and guidelines. Proper installation is crucial for optimal performance and safety. The actuator is designed for straightforward installation, but attention to detail ensures that the trailer’s braking system integrates seamlessly with the tow vehicle’s brakes. Ensure that your trailer’s tongue size matches one of the supported sizes: 3”x3”, 3”x4”, or 3”x5”.

Compliance and Safety

Adherence to your state’s braking regulations is mandatory when installing any brake system. While brake laws often represent minimum required standards, enhancing your trailer’s braking system beyond these standards can provide additional safety margins. The Model 660E Actuator complies with standard braking regulations, but boat owners should verify local laws to ensure full compliance and optimize safety during towing operations.
