It works, I kept burning 40 amp relays on my Spal fans to the point that they would burn your hand to the touch. I went through 5 relays in the span of about a month & a half.I narrowed down the root cause of that to be the fuse system as running these fans on startup can spike over 60+ amps yet they're rated for 30amp fuse with a 40 amp fan setup.I purchased these & a larger base fuse setup & now these run warm and very warm on extended hot days where the fans kick on and off multiple times.I inspected the pigtails pins to make sure they were all crimped properly before installing them as there's comments of people having had them improperly crimped and the wires puling out. I can confirm that my crimps looked good upon inspection, I do own a crimper so I was ready to make the adjustment myself.These work well they're a solid product, with larger pin terminals so no they won't fit in a regular relay slot but they are in the form factor of a regular 30-40amp relay which is great.

I needed HD Relays to install 2 high flow Radiator fans on my Truck, plus a set of steel Air Horns as well. And for the Amps being drawn, these Relays are so perfect, had these Relays working for well over a year now, and going strong.

I purchased these relays to replace the failed units in the electric winch, used to raise the roof on my popup trailer. These were one-third the cost of ordering replacements from the manufacturer! They work perfectly - every bit as good as the originals. The included bases/sockets are equipped with decently gauged wiring. The wires are stranded, but at the supplied lengths, they are adequate for the relay ratings. After rewiring my winch with the included bases, it'll be a snap to replace the new relays... someday. These relays seem very well made. I am satisfied, and would buy again. In fact, I did. Ordered up a second set for another project!

Decent product. Difficult to press the solenoid in. Instructions are printed on the solenoid but lack wire color.

I just got these and pull on the wires to make sure they were not going to come off as some people experienced. No problem with the ones I got. I did end up swapping the red and yellow wires since I like the red to be my positive 30. I also added the pin numbers on the outside casing so I can easily see what's what after it's installed since It's hard to see the diagram in the dark places. I do like the thicker wires on these. I have not installed them yet but tested the leads to make sure the wires are working. They are hard to push all the way down or take them out which I guess it's a good thing. However be careful when taking them out since the casing is plastic and easy to pull out.Update - March 28, 2025.I finally got one of these installed in a car alarm starter cut-off that kept giving me staring problems during hot days. It turned out the small relays were just not working. I also re-connected the ignition wire to make sure it wasn't that as well. So far I have not had any more problems after using this relay. Maybe it's the cheaper relays just don't hold up anymore, I'm not sure but I'm glad this problem is now fixed because my car turns on every time now. I'm just glad these are better relays.

These are perfect for what I needed. I wanted to add an accessory fuse box to my side by side, and this is what I used to power it. I wanted the fuse box powered from the battery but turned on by the key. Exactly what I needed. Works perfect and I like the fact that it is 80 amps which makes sure that I don't overload it. Highly recommend.

Awesome amazonian!!

Product was high quality with large spade connectors. Would recommend
