Towing can be dangerous and stressful. No one likes to anticipate a trailer breakaway, but it can happen. By triggering your trailer's brakes, the Curt Manufacturing Soft Track II Breakaway System helps to prevent a runaway trailer if the trailer detaches from the tow vehicle. The kit can be purchased with or without the charger, includes a battery case to protect the battery and charger from harsh weather, meets or exceeds DOT specifications, and attaches to the trailer's jack post or A-frame with one bolt for easy installation. MSRP: $65 with battery charger, $57 without.
