Features to know about

Reliable Stops in Emergencies: Intelligent Breakaway Activation

Picture cruising down the highway with your trailer and suddenly it becomes disconnected. With the Curt Soft Trac I Trailer Breakaway Kit, you have the confidence that your trailer will come to a complete stop. Once the pin from the switch is pulled, a signal is instantly sent to your trailer brakes. This intuitive design keeps you and your fellow motorists safe, as the breakaway system can fully engage the brakes for at least 15 minutes.

Seamless Battery Readiness: Automatic Charger Integration

One of the best things about this kit is its built-in battery charger. You don’t have to worry about whether the battery is ready for action; it automatically charges when your trailer is connected to your vehicle. This means your breakaway kit is always prepared, giving you peace of mind before every journey. The 5-amp hour, 12V sealed lead-acid battery is kept in optimal charge, ready to power your trailer’s brakes should the need arise.

Simple Installation with Versatile Mounting: Side-Loading Design

Mounting a breakaway kit shouldn’t be a hassle, and with the Curt Soft Trac I’s side-loading case, it won’t be. It provides easy access to the battery, whether you're mounting to the trailer frame or the jack post. With included U-bolts and an option to use self-tapping screws, attaching this kit is straightforward and adaptable to your trailer’s needs.

Weatherproof Durability: Comprehensive Battery Protection

Worried about rain and debris damaging the battery? The durable plastic case of this kit is designed to shield the battery from harsh weather conditions. With a rubber O-ring to keep moisture out and an option to secure the lid with a padlock, it enhances protection against potential theft and environmental damage.

Compatibility with Multiple Trailer Types: Designed for Versatility

Whether you’re towing a single, tandem, or triple-axle trailer, this kit has got you covered. Its versatility extends to different axles, making it an ideal choice for various towing setups. It’s also Department of Transportation (DOT) compliant, which means it adheres to necessary safety standards for trailers over 3,000 lbs, fulfilling legal requirements in most states.

Engineered for Effortless Maintenance: Low Fuss Breakaway Switch

A common concern is the breakaway switch, but Curt Soft Trac I has made it quite robust yet easy to manage. Although the pin requires some force to pull out by hand (ensuring it doesn’t fall out unintentionally), it’s designed such that the weight of a trailer would activate it if needed. This system minimizes the risk of accidental disengagement, keeping your trailer secure throughout your travels.

The battery can be tested for 14Vh. During the operation, the system provides a trickle charge to maintain battery voltage. When battery voltage is under 6V, the tester circuit will not have power and the red or green light on the switch will not activate, indicating that the battery is dead. I recommend using a break away kit with a battery tester like item # 20099.



by:

The u-bolts worked great for mounting the battery box on an electric tongue jack. I ended up heat shrinking the leads coming out and then siliconed the hole so no water could get in. I was not able to fully test the break away switch and stop the trailer with the battery but feel confident in the product.



by:

I also bought a new plug with attached junction box. The battery and charger were straight forward to wire. The only problem I had was that my old trailer wire colors did not match the new plug colors. Once I sorted out my wires everything worked well. I think it is a good battery kit



by:

HAD TO DRILL NEW HOLES BUT OTHERWISE INSTALL WAS EASY JUST CUT AND CRIMP WIRES USED HEAT SHRINK AND SEAL BUTT CONNECTORS.



by:

This was a replacement for an aging unit. Installation was straightforward. I hope to never need the unit as it would only come in to use in the event of a loose trailer so I cannot comment on it's function.



by:

Good web site, good value, great instructional videos. Quick delivery!
Wish it had a battery stus indicator. Only one that fit the jack.
