Demco TI210SB Tow-It with Surge Brakes
The Demco TI210SB Tow-It integrates surge braking with a robust, fully enclosed design to protect towed equipment. It features low tongue weight when loaded (around 100 lbs.), preventing excessive load transfer to the towing vehicle. The fenders are polyethylene, dent- and rust-resistant, offering durable protection for the towed vehicle. A 5th wheel design and swivel platform contribute to versatile trailer handling, while sure-grip galvanized ramps improve loading confidence.
NSA RV Ready Brute Elite II Tow Bar with Integrated Surge Brake System
The Ready Brute Elite II combines an 8,000 lb aircraft aluminum tow bar with an integrated surge braking system, delivering proportional braking without requiring separate components. It is designed to be lightweight (about 48 pounds) and features non-binding T-latches along with rotating clevis connectors for easier hookup on uneven surfaces. The system supports straightforward installation adjustments and includes the DL-100 Dash Monitor System for driver feedback. It is positioned as a complete, all-in-one solution for towing up to 8,000 pounds.
Demco DA70 Surge Brake Actuator for Hydraulic Drum Brakes
The DA70 actuator is rated for up to 7,000 pounds gross towing weight, designed specifically for hydraulic drum surge brake systems. It uses a 2″ ball coupler for a secure connection and reliable engagement with the towing vehicle, providing smooth, proportional braking responses under load. This actuator is suitable for trailers requiring hydraulic drum braking with a robust, mechanical surge input.
Sturdy Built Demco Hydraulic Trailer Disc Brake Surge Actuator
This actuator provides hydraulic disc braking with surge assist and a 7,000 lb capacity. It uses a 2″ ball and includes a solenoid-equipped electric lockout option for controlled disengagement, enabling safer parking and maintenance. Mounting is designed for typical 3″ wide trailer tongues, optimizing integration with compatible suspensions and frames.
DLFZWB 2-inch Ball Model Hydraulic Trailer Actuator
The DLFZWB actuator offers heavy-duty hydraulic braking with a 7,500 lb capacity and a sliding inner mechanism for easy installation. It employs hydraulic pressure to engage the brakes, delivering responsive stopping power for trailers with substantial towing weight. The system is designed for straightforward alignment and adjustment to maintain efficient brake performance.
Buying Guide: Key Purchase Considerations for Tow Dolly Surge Brakes
When selecting a surge brake system, consider compatibility with your trailer tongue width and ball size, maximum towing weight, and brake type (hydraulic drum vs. hydraulic disc). Actuator capacity should meet or exceed your trailer’s GVWR to ensure safe stopping power. Look for features that affect installation ease, such as non-binding latches, clean routing paths, and dash monitor compatibility where applicable. For integrated systems, ensure the tow bar and braking unit share a common mounting interface and weight target to avoid excessive tongue load.
Other perspectives include:
- Maintenance requirements: Disc brakes generally offer improved cooling and resistance to heat fade but may require more frequent inspection of hydraulic lines and solenoids.
- Ease of installation: Systems with floorboard routing or pre-mounted hardware reduce installation time and potential firewall drilling.
- System integration: Some setups are designed as all-in-one solutions with dash monitors, while others are modular and allow upgrading components later.
- Durability and protection: Enclosed components and rust-resistant materials extend life in outdoor environments and when stored after use.
- Compatibility with existing equipment: If you already own a 2″ or 2-5/16″ ball setup, verify the actuator’s ball size and the tongue width to ensure a proper fit.
Overall, the best choice will align with your towing weight, ease of installation, and preferred brake type, while offering reliable safety features for frequent highway use.
