I just opened up my new Class 5 Curt XD hitch and have not yet installed it so my comments are based on first impressions only. It is very heavy duty - and heavy at 40 lbs. - made of extremely thick metal and outfitted with quality Grade 8 bolts with square necks so they won’t turn when torquing on the nuts to attach the main tube to the side mounting plates. My bolts are plated yellow (which I like) rather than silver as you may have seen in some online photographs. It is substantially beefier than my existing Grade 4 hitch and superior in every way. It’s an impressive piece of hardware. I cannot imagine anyone being disappointed with it on specifications, quality, strength, and general appearance. It’s a beast. What I AM disappointed in is Curt’s packaging and the condition in which the hitch arrived. (This is NOT a reflection on etrailer.com as the hitch arrived in Curt’s original packaging.) The unassembled main tube and the two side mounting plates come bundled together with nothing separating them but shrink wrap. No cardboard, plastic, even paper coming between the metal surfaces - just shrinkwrap probably not even a couple of mils thick. With basically metal-to-metal contact in an oversized-box with the bundle jostling around, it would be a miracle if there were no scratches, gouges, or some type of damage to at least one piece, which is exactly what happened to my hitch. The main hitch tube, on the exterior facing plane, on the driver side where I’ll see it every day, has some gouges on it that go through the powder-coating to bare metal. I can - and will - paint them to prevent rust (and, therefore, have to paint the whole hitch to match). But the gouges will still be noticeable as they go through the thicker, pebbly, powder-coat finish and will undoubtedly still appear as depressions in the surface even once painted. I fully realize this kind of surface damage will almost certainly happen with regular usage of the hitch anyway and that it’s certifiable to demand absolute perfection in anything. But if you are someone who cares about the aesthetics of your equipment and keeping it looking new for as long as possible, it is very disappointing to receive such an expensive and prominent piece of hardware damaged right out of the box and requiring immediate repainting. The plastic parts bag had also ripped open in transit, with nuts, bolts, shims, etc. rattling around in the box. I am dumbfounded that Curt packages such a high-quality piece of equipment so shoddily where such damage is virtually unavoidable. I bought from Curt solely due to their being an American manufacturer and to support American workers so this is doubly discouraging. It’s a trivial complaint in the big scheme of things and not worth demanding a replacement over. Just be aware that unless Curt changes their packaging practices it is very possible you will have the wind taken out of your towing project sails just as I have. Again, this in no way reflects on etrailer. My experience to date with etrailer (website, educational resources, staff reviews, ordering, tracking, email contact, etc.) has been beyond exemplary in every way. They rank as a Top Five online retailer in my opinion, maybe even the best.

Not an etrailer issue, but the manufacturer included installation instructions with schematic that did not match the product.
by: Dale 08/15/2023
This unit was to replace the ancient breakaway unit on my 2-axle trailer. Installation went smoothly - good unit!
by: Tyrone 06/20/2023
Very nice system. Exactly what I needed to make my trailer compliant. Unfortunately one of the mounting feet for the breakaway system was broken during shipping but I'm sure etrailer will make it right.

Just what we needed to replace the breakaway on our cargo trailer.

Works great. Plug and play.

The box was missing parts. It didn’t have the Breakaway switch. The box showed up in poor shape. Refund requested

Item was exactly what I needed, thanks to Paul’s help over the phone.

One year later and still working great. Love the charge status lights that let me know all is working as it should.

Installed and tested correctly. Wish it were made in America.

Very reliable and well-constructed kit. Doing a great job with stopping my 15k lb boat and trailer.

got the product here in a timely manner.
by: Kevin H06/07/2016
Replaced a outside rail unit on my Trailex enclosed (1999) with this unit, but moved it inside by winch mount to better protect from elements. 1 year in, start of new towing season, still working as designed (brake engage), charging off of tow vehicle 12v power from 7-pin cable source.
Would buy again to replace a dead battery, to all new accessories, not a place to scrimp.
by: Al10/21/2021
Product seems to work however the instructions that came with it had the correct part number but the wiring diagram was wrong. I contacted etrailer and they confirmed that and emailed me a more current diagram which was also wrong. I contacted curt and the first tech told me there was a wiring issue with my trailer. Finding none I called again and was told the first tech was wrong. Then I noticed the diagram on the control cover and it is correct and seems to be working. Called curt again and they said they are looking into the instructions issues.
by: Chris - Detroit05/14/2019
Very good product. Don’t want to see a trailer with thin enough steel that the mounting screws would actually work.
Did have a bit of a hard time mounting since the bolt spacing was pretty wide, but got it to work.
Kit is complete, works very well, and was relatively simple to install.
Recommend it for the money.
by: Mike K07/07/2020
Great product to use when swapping out the old surge brake system for a new electric system. Only needed to buy wire and waterproof connectors and I was set.
by: Jeremie03/31/2021
This item is as expected and was fairly simple to remove my old Curt trailer breakaway brake and wire as old one. Seems to do what it is supposed to. I like the indicator lights.
by: William09/05/2020
Curt makes good stuff, their people are helpful. Unfortunately this kits instructions do not match the wire colors. I informed Curt of this.It shows hooking up black wire from battery/test panel (neg) to ground. The wires from the battery/test panel box are red,white and blue, NO black.I understand how to wire this in any case.
by: Aaron 11/09/2021
Wiring was a little short for my existing harness box. Screws rusted out and the buttons and box is faded. I don’t recommend install on a virtual plane.
by: Shane05/25/2022
Good quality, fit was good and they held up well upon yearly inspection.
by: Lee 09/27/2021
easy to connect and install. However, some wiring instructions enclosed differed from the actual wiring on the battery. The wiring diagram on the cover of the battery box was correct.
by: Larry03/16/2018
Easy to install, drill 3 holes, hook up wires, done. Works great when tested, instructions were clear enough for even me.

Not well. I dont know if I wired it wrong or what, but the battery died. Everything checks out ok with a multimeter except the dead battery.

If the vehicle 7-way that you are using this with does not have a powered 12-volt connection to help maintain the battery then that may be the issue. If not then check out the installation instructions and refer to page 2 for additional info.
by: Kenneth 12/13/2020
Very impressed with etrailer. I've purchased a goosenect connection for my f350 and it has been impressive. I love your products, the way you provide detailed info about each item, videos, photos, dimension, capacities, etc. Way better than anywhere else I've seen. I've found prices to be reasonable. Service has been great with fast delivery. I will definitely continue to shop at etrailer.
by: Steven 07/30/2022
Helped make my trailer project look very professional.
by: Joseph 02/01/2022
The people at etrailer are excellent. They kept me up to date on my backordered items and got me all the parts I need. I have ben a customer for several years and I will not go anywhere else.

- How To Wire the Curt Push-To-Test Trailer Breakaway KitIn regards to the Curt Push-To-Test Trailer Breakaway Kit part # C52042, the blue wire on the breakaway switch will be run to the brake output circuit and the black wire to a constant 12 volt power source. The blue wire on the battery box will also will be run brake output circuit, the red wire to a 12 volt power source, and the white wire to a ground.
view full answer... - Where to Attach Cable for Curt Push-To-Test Trailer Breakaway Kit The most common method for attaching the cable for a breakaway kit like the Curt Push-To-Test # C52042 that you referenced is feeding it through the safety chain loop on the trailer hitch. The warning message that you mentioned on the instructions manual caught me a little off guard so I called my contact at Curt and he actually said that "mounting hooks" in that statement refer to the hooks on the safety chains themselves. He said that the cable can absolutely be connected to the tow...
view full answer... - Could One Trailer Breakaway Kit be Used on Several Fifth Wheel TrailersBreakaway kits aren't really designed to move from trailer to trailer easily. They are designed for a permanent install. Since nearly all areas will require a breakaway kit to be installed on the trailer the best solution would be to install a breakaway kit like the part # C52042 on all of the trailers. It'll also save you a lot of time trying to swap the kits each time you have to tow a different vehicle.

The blue wire on the battery box will also will be run brake output circuit, the red wire to a 12 volt power source, and the white wire to a ground. Unfortunately, we do not create any of the wiring diagrams for Curt as they are the manufacturers.
view full answer... - Breakaway Kit Not Working Properly and Causing Issues with my Brake ControllerIf I understand correctly when you hit the brakes in your truck the trailer brakes work fine. Then if you pull the pin on the breakaway switch the trailer brakes do not work and will not work again even using the truck until you put the pin back in the breakaway switch. If this is the case there is a wiring problem with your breakaway kit the main trailer brake wire should run directly to the brakes and the breakaway kit should only be spliced into that. It sounds as though the trailer...

view full answer... - Comparing Trailer Breakaway Switch KitsSome different brand names of trailer breakaway kits do originate from a common source, and this is also true for items like jacks, landing gear and steps. There really is not a lot to distinguish one from another, since their component parts are virtually identical: a battery, a box, a charger and a switch. The one part that can make a difference is the battery itself. A higher output battery can power brakes on more axles. Hopkins Engager Trailer BreakAway Kit # 20400 can handle 1 or...
view full answer... - Best Breakaway Kit with Push To Test Feature for Triple Axle TrailerI do have an option for you but the Hopkins Engager Push-To-Test Trailer Breakaway Kit w/ Built-In Charger part # 20099 is only rated for use on single and tandem axle trailers. For a breakaway kit that is rated for use on triple axle trailers you will want to use the Curt Push-To-Test Trailer Breakaway Kit with Built-In Battery Charger part # C52042. The Curt breakaway kit as the title suggests also has a built-in push to test feature as well as a side load battery box just like the Hopkins...
view full answer... - Should Breakaway Switch be Wired to Auxiliary BatteryIt sounds like your breakaway switch is wired to your auxiliary battery, which is not something that should be done, and can explain the backfeeding (which also should not be occurring). So what you will need, and something that is required by law in many states, is a breakaway kit with its own dedicated battery: - Curt Push-To-Test Trailer Breakaway Kit with Built-In Battery Charger # C52042 I have added a link below to a video review for you to check out as well of this kit.
view full answer... - Troubleshooting Install of Curt Breakaway Kit on Trailer Where Brake Lock Up Since your trailer doesn't use standard colors for it's wiring for lighting and braking you are going to have to wire in the breakaway kit # C52042 by function instead of by color. I won't be able to tell you which color is which on your trailer as you'll have to determine that by either tracing the wiring or using a jumper wire from a car battery to first determine all of the functions. So the red wire of the # C52042 needs to connect to the 12 volt accessory circuit of your trailer wiring....

- Replacement Breakaway Switch for Trailer Breakaway SystemYes the Curt Push-To-Test Trailer Breakaway Kit # C52042 would work as a replacement breakaway switch replacement but it comes with probably more components than you'd need if you only need the switch. Instead you could use the part # 420000 which is a universal switch that can basically fit any system. This would wire in exactly like your current switch. Either wire can be used as the power or ground.
view full answer... - Will a Curt Echo Wireless Brake Controller Work with Drum Brakes?The Curt Echo Wireless Trailer Brake Controller item # C51180 is a proportional brake controller that will work perfectly with the drum brakes on your 2013 XLR Hyperlight Toyhauler. Drum brakes can be electric or hydraulic and the Curt Echo is compatible with both. I recommend the Curt Breakaway Kit with Built-In Battery Charger item # C52042. This breakaway system activates your trailer's electric brakes if the trailer disconnects from the tow vehicle and comes with a built in charger....
view full answer... - Is There a Curt Soft Trac Breakaway Kit that Has Battery Charge IndicatorIf you are looking for a similar trailer breakaway kit that has a built in charger and tester we have the Curt part # C52042 which will show you when it's charging and charged but the part # C52040 that you referenced does not have this feature.
view full answer... - Mounting Hole Pattern of Curt C52042 Push to Test Trailer Break Away System Battery BoxI had one of the # C52042 push to test break away kits pulled from inventory, and found that the bolt pattern of the # C52042 measures 5-1/2 by 3-1/2 inches. I've linked though our in-stock systems and haven't found a push to test break away kit with the same 3 x 4-1/2 bolt pattern as the # C52040. However, since the # C52042 is larger, you could simply fasten it to the trailer frame by drilling through the bottom of the battery box, if you're reluctant to drill new mounting holes into...

- Does Charging Battery of Curt Breakaway Kit # C52042 Take a Long TimeTo charge a battery through the 12 volt accessory circuit of a vehicle and trailer wiring does take some time. If the battery was in a pretty low state of discharge it would not surprise me that it's still charging. If you wanted to charge the battery quickly you'd need a charger that plugs into a wall outlet like the part # CTEK56353.
view full answer... - What Breakaway Device Do You Recommend for My 2021 Jayco Travel Trailer?As far as the cables/plugs that come with breakaway systems, they are virtually universal for trailers. As far as a great breakaway system for your 2020 Hay Flight 29RKS, the breakaway options depend on where you want to mount the switch. For the best options, I recommend the Bright Way Push-to-Test Trailer Breakaway Kit with 1-Amp Charger and 5 Ah Battery # 3802308 (top loading) or the Curt Push-To-Test Trailer Breakaway Kit with Built-In Battery Charger # C52042 (side loading).

view full answer... - Brake Away Switch And Battery Disconnect Compatibility The breakaway for your trailer should have it's own dedicated battery like the Curt Push-To-Test Trailer Breakaway Kit with Built-In Battery Charger Item # C52042 does. The built in battery charger receives power from your 7-way connection to recharge the battery so you won't be hooked up to the trailer's battery at all and won't have any issues with your battery disconnect switch.
view full answer... - How To Move A Trailer With A Dead Breakaway BatteryOn most breakaway kits such as the Hopkins Brake Master part # HM20001, you will not need to cut or splice any of the wires to move the trailer with a dead battery. If your power supply is not active, then the only effect is that the breakaway system will not send power to your trailer's brakes in a breakaway situation thus allowing for free movement of the trailer. Even if the battery is dead, the brake controller will still allow you to activate your trailer's brakes To prevent further...

- Breakaway Kit and Wiring Needed To Connect Brakes On a Utility Trailer and Brake Controller 2012 RamFirst you will need a Trailer Breakaway Kit # C52042. This will include a breakaway battery and breakaway switch.
