When you’re pulling a trailer and facing an emergency stop, a fraction of a second can translate into a few too many feet in stopping distance. Cargo’s Hydrastar trailer brake actuators deliver the industry’s fastest response time to provide maximum braking safety for your towed trailer/vehicle. Industry-leading Hydrastar actuators are easy to install and meet all DOT and federal braking requirements – unlike surge brakes which are illegal in many states. Hydrastar has improved the stopping performance for trailers hauling boats, RV/towables, horses, cars, construction, farm equipment, and many other loads.
