Trailer Brake Actuator Model 660 With Drum Brake
This brake actuator is designed for drum brake systems with a 6600-pound gross vehicle weight rating and a 660-pound tongue weight. It’s best for mid-size boats on trailers that rely on drum brakes. The actuator’s compatibility makes it a solid choice for single-axle setups or light tandem configurations where drum brakes remain in use. Limitations include compatibility primarily with drum brake systems, so verify your trailer’s brake type before purchase.
Master Cylinder Parts For 2 Inch Ball Actuator
This kit is engineered for 2-inch ball couplers on trailers with tandem axles. It delivers consistent hydraulic pressure for smooth brake actuation and is designed for hydraulic disc brake systems under heavy towing. Choose this if your trailer uses a tandem-axle hydraulic system and you want reliable brake response. A potential limitation is the need for correct compatibility with your specific disc brake setup.
Demco Heavy Duty Tongue Coupler 2 5/16
Demco’s heavy-duty tongue coupler supports up to 18,000 pounds and features an EZ Latch design for quick, secure lowering onto the ball. It’s made from heavy-duty steel with a zinc-plated finish, and is Made in the USA. Best for large boats and heavy trailers where a robust, easy-latch system is valuable. Caution: ensure your hitch ball matches the coupler size (2 5/16 inches) and that your trailer frame can accommodate the higher capacity.
Boat Trailer Rubber Brake Hose 24 In DOT
This DOT-certified brake hose is ideal for boat trailers with disc or drum brakes. The 24-inch length with stainless steel flared ends and brass fittings provides flexibility for varied trailer layouts. Best for: mid-length trailers needing reliable hose extensions. Caution: verify your brake system’s compatible hose length and end fittings before ordering.
Sturdy Built Boat Trailer Brake Hose 4 Ft 9 In
Another DOT-certified option, this 4 ft 9 in hose offers durability and brass fittings necessary for robust brake lines on longer boat trailers. Best for owners needing extra hose length without sacrificing reliability. Limitation: longer hoses may require careful routing to avoid snagging on rough terrain or debris.
Buying Guide

- How do I know if my trailer needs a 2″ ball or a larger size? Check your existing hitch ball size or the trailer’s specification plate.
- What maintenance steps prevent brake hose failure? Regularly inspect for cracks, leaks, and corrosion; replace hoses showing wear.
- Are DOT-certified hoses mandatory? DOT certification indicates standard safety and reliability; it’s commonly preferred for marine trailers.
