Average Customer Rating:  4.7 out of 5 stars   (7 Customer Reviews)

The material was delivered as promised. It seems to be as stated on the web site. But my truck is in the body shop for repairs, both skin panels for the box had to be replaced. so I am waiting to get the truck back. I also have to buy a cargo trailer and will need to buy more stuff for it. so I have no experience using what I have already purchased. After the truck and trailer are finished I am moving to Washington State.
It will be a few more months before I can sell the house.


I installed the kit easily ! I sold the trailer soon after.


Great quality products! Good prices. Well put together kit with every thing I needed. Outstanding customer service.


Great kit, does the job.


Looks like what I need

  • Troubleshooting Trailer Breakaway Wiring that Melts When Pin is Pulled
    Do the brakes seem to work fine when used normally? The Tekonsha breakaway kit # 20020 normally can be used on trailers with up to 4 brake axles. The problem has to do with the amount of amperage draw the brakes are trying to put on the system and not the battery though. I'd look for a short on the trailer's wiring or maybe you have a bad trailer magnet. I attached a help article on troubleshooting trailer brake magnets for you to check out as well.

  • Trailer Breakaway System Recommendation for a Triple Axle Gooseneck Trailer
    The breakaway kit I recommend for your trailer with 3 axles is the Tekonsha Breakaway Kit with Charger, part # 20020. This has a heavy-duty two stage charger included and sealed rechargeable 12V battery. This kit is designed to work with trailers that have up to 4 axles.

  • Is it Okay to Insert the Breakaway Pin After it Accidentally Became Unplugged
    You will have no problem at all. The pin on the breakaway switch simply closes or opens the circuit from the breakaway battery to the trailer brakes. In fact, many people like to test their trailer brakes by pulling the breakaway pin. As long as it is fully inserted, you are good to go. If you broke the pin, cable or box, I attached a link to all of our replacement pins and cables and a link to our replacement switches for you to check out. Be sure to choose a pin with the same design...

  • Does Tekonsha Breakaway Kit 20020 Require Additional Circuit Breaker
    Your trailer brakes won't necessarily draw 30 amps when activated so the Tekonsha Breakaway Kit part # 20020 will still work fine even though it uses a lighter gauge wire. 20 amps is the size breaker that is recommended for the circuit to protect it since it's a tandem axle but that does not imply that it draws 20 amps all the time. We have found that this kit works well from what our customers have came back and replied with. No additional breakers will be needed.

  • Do Tekonsha Breakaway Kit with Charger, # 20020 and # 2028 Come with the Same Charger
    Both the Tekonsha Breakaway Kit with Charger, # 20020, and the Tekonsha Breakaway Kit with Charger, Clamp On, # 2028, come with the same charger. The only difference is how each system mounts to the trailer. Break away batteries require a special charger because they are smaller than a regular 12 volt battery. Trying to charge it just through the 12 volt circuit from a trailer connector can overcharge the battery. The charger prevents that from happening after the battery has been charged...

  • Recommendation for Mounting Quick Fist Super Clamp # QF20020 to Enclosed Trailer Walls
    Due to the weight of a scuba tank and extinguisher I would recommend using a mounting plate to tie the Quick Fist Super Clamp # QF20020 to two studs. That's quite a bit of weight and you'll want all the support you can get.

  • Quick Fist Super Clamp -QF20020 Weight Capacity
    The working load limit of the Quick Fist Super Clamp - 2-1/2 to 9-1/2 Inner Diameter - Rubber - 50 lbs Item # QF20020 is 50 lbs which means it has a break strength of 150 lbs. It should last you a really long time but it has a 1 year warranty. Beyond that it's hard to say an exact length. We can not give out any type of CAD drawings or 3D models.

  • Replacement Trailer Breakaway Kit Recommendation for Trailer with Trailermate Kit
    For a replacement breakaway kit the Tekonsha kit part # 20020 would be a great option to replace everything. You didn't mention which parts you'd need to replace though. Commonly people want to replace just the switch which for that you would want the part # 3802348. Due to the universal nature of how these install it would easily replace the switch you have if that's what you were in need of.

  • How Does Fire Extinguisher Mount QF20020 Release from Holding the Tank
    You are correct, basically all you have to do is pull outward on the strap of the extinguisher carrier part # QF20020 to get it to release from the other side of the strap. If you fast forward to the 1:00 mark of the video link I attached (probably below the parts links) you can see the smaller version of this carrier getting released.

  • Does Breakaway Kit Cause Backfeeding on Brake Controller Wiring
    Since breakaway kits attach to only the 12 volt accessory circuit of the trailer wiring under normal circumstances and not the brake controller output circuit like what the brake controller is connected to there would be no backfeeding issue. In the event of the breakaway kit getting activated and it putting 12 volts on the brake output circuit the trailer wiring would be at that point disconnected from the vehicle so again there wouldn't be any backfeeding. Also 12 volts on the output...

  • Breakaway System with Charger for a 20 Foot Car Hauler Trailer
    For a breakaway system with a built-in charger I recommend the Bright Way Push-to-Test Trailer Breakaway Kit # 3802311. This is a popular option because it is all in one and has a push to test feature to monitor battery charge level.

  • Solution for Breakaway Pin on Trailer that Wont Come Out
    If you have a breakaway switch where you can't pull the pin out it's probably a good time to replace the switch. It sounds like the cable might have broken before the pin would come out which is not a good sign. For a new switch you can use the part # 3802348 which due to the universal design of these switches will work with what you have regardless of if it's a Tekonsha setup.

  • Could Road Debris Pull the Pin on Trailer Breakaway System
    Once the pin on the break away switch is pulled, the brakes on the trailer will engage. I have not heard of this occurring, but it is possible. I would recommend routing the cable that pulls the pin as close as possible to the trailer frame. You can use a few strips of electrical tape to hold the cable in place so that it is not hanging down and easily snagged. If the trailer should come loose and the safety chains should fail, the tape would not prevent the cable from pulling the pin...

  • Troubleshooting Trailer Breakaway Kit on Trailer with 2016 Ram 2500
    Typically, a trailer breakaway kit will have enough power to engage the trailer's brakes for fifteen minutes once the pin is removed. So, if the pin was removed while your vehicle was idle, then it's possible that the battery had died before getting back on the road during your trip. This would explain not noticing the brakes locking up while driving, even though the pin was not present. If you need a replacement battery, you can use the Hopkins Breakaway Kit Replacement 12V Battery #...

  • What 3-Axle Breakaway Kit Comes with a Test Feature and a Charger?
    Yes! The only model we carry that is compatible with a 3-axle trailer and has a test light/charger on the battery case is the Curt Push-To-Test Trailer Breakaway Kit with Built-In Battery Charger - Top Load # C52044. I went ahead and attached a demo video that walks you through the features. It is important to note that you need to have a brake controller that works specifically with electric over hydraulic brakes in order for this breakaway to be compatible with your setup.

  • How To Keep a Breakaway Battery Charged While In Storage
    In order to keep the battery on a breakaway system charged while in storage you have two options. The best option for you is going to be based on what resources you have available. If the trailer is stored outdoor then you can use the 2.5-Watt Solar Battery Charger part # PTW2997. If you don't have access to power and the trailer is stored indoor then you will want to remove the battery from the trailer and then take this home with you so it can be hooked up to a battery charger where power...

  • Can Trailer Connector On Truck Charge Trailer Breakaway Battery Once It Is Dead
    The current from the truck will not charge the battery in the Tekonsha Breakaway Kit, part # 20020 if the battery is completely dead. My contact at Tekonsha told me that it will charge the battery at a very low rate if the charger senses any charge on the battery. The charger in the 20020 will maintain a charge for the breakaway battery once it reaches its full charge. My recommendation is to use a battery charger like part # CTEK56865 to charge the battery when it is not being used. This...

  • Can Battery Used for Breakaway System Also Power Interior Lights
    If you had a larger battery than what comes with a breakaway kit like the # 20020 it could be used to power interior lights as well as perform the breakaway function, but legally this would be something you'd have to check with your local DOT on. We have slightly larger batteries like the 20.5 amp hour # BRW97FR.

  • What Pigtail do I need to Install a Tekonsha Brake Controller in my 2003 GMC Sierra 4x4
    The correct adapter for your 2003 GMC Sierra is in fact the Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers part # 3015-P. This will allow you to plug the Tekonsha Prodigy P2 Trailer Brake Controller part # 90885 directly into it and have a functioning brake controller. Check out the video that I linked for you. This will show exactly where to plug in your pigtail and will give you a good mounting position option as well.

  • Will the Roll Bar/Bull Bar Mounts for Quick Fist fit Yakima CrossBars
    I reached out to Quick Fist and have two possible solutions for you to make the # QF90050 fit the 1-1/8" crossbars. The first is to use the 1" snap-in inserts. Although they are designed for 1" you will likely be able to tighten them down enough to secure the mounting brackets without adding any additional material. The second option is what you suggested, which is to use the 1-1/2" snap-in inserts and fill the remaining space with rubber/foam for a secure fit. This is perfectly acceptable...

  • Can the Side Wall Adjustable Shelf Supports # RA-24 be Used for PVC and Iron Pipe
    The Side Wall Adjustable Shelf Supports # RA-24 would work much better for PVC pipe organized than it would the black iron pipe. The issue with the pipe is the weight. Too much of it would be too heavy for this system. Using several of the Quick Fist Super Clamps, # QF20020, might be a better solution. Each clamp can support up to 50 pounds.
