My ARB compressor wouldn’t switch on and fortunately it was just a bad relay after years of being in a hot engine bay. 5x cheaper and delivered in one-day thanks to Amazon. Going to order a spare to keep in the truck in the event it fails in the backcountry.

Needed this style and this is about half price of local and a good brand.

These are a great replacement relay for anyone with an air lift performance system. We've all been there when something goes weird just to find out the relay is bad. Quick switch out and direct fit.

Been on for almost a year now and still works fine, plastic mounting tabs usually worry me but this one is sturdy.

Not entirely the vendors fault but please note that this is a 4 prong/post relay. It's missing the center connection so can't use it for my application.Other than that looks like a high quality relay compared to the other ones I've got from EBay and such.

Simple, inexpensive robust (40 amps). I use it to run my bilge pump to cut down on burning out bilge pump switches. I have used other realys for this purpose, the all seem to work OK, but this was a very good price and most other relays are only 30 amps. I don't know if there is really a difference, but will go with the specs. arks are arks, the bigger the contacts the longer they last. Of course with all of this kind of stuff, until it has been in for a few years we really don't know do we? But it looks good so far.
