Today we'll be having a look at the Etrailer replacement spring for 7,000-lb and 12,500-lb ram sleeve lock couplers, part number CA-5196-SPR. Here's what our replacement spring looks like, we'll flip our coupler over here and we'll show you what this is used for. This spring is what pushes open our coupler so it'll lock down onto our ball. What you need to do to get it out, just grab a hold of it, remove it, take your new one, push it in the hole, push back down, and that gives you the spring loaded action you need to hook your coupler up to your ball so you can tow your trailer. The reason you need one of these replacement springs is in case you misalign and try to put your ball on, you might pop the spring out and lose it, overtime these could get damaged too from becoming weak and brittle. It makes it a lot easier to hook your coupler of your trailer up to your ball. That completes our look at the Etrailer replacement spring for 7,000-lb and 12,500-lb ram sleeve lock couplers, part number CA-5196-SPR.
Ratings & Reviews
No issues. Arrived on time.
exact fit. Worked great!!!
I have an older trailer - 1997 Thoroughsport.
This spring works, but is a tiny bit small. I think one more rotation of wire would do the trick.
I need to be mindful were it is, when hitching up to the truck, so it doesn't fall out, and I lose it in the grass/dirt.
Simple install and fast delivery
Little tough to compress, but with patience it will go in. Brought coupler back to life.
Just what I needed
Works as it should.
Thank you.
This site has everything that ypu might need. Great service. Once part arrived, one of there members emailed me to tell me it had arrived and I received a link to and install video fotlr the part I purchased!
Thank you
Did the job. Put it in, forgot about it until etrailer asked me to do a review a year later. What more can you ask?
Great service and great products. I will purchase again.
Very easy to order and the part came in early.
Worked awesome
Worked perfectly on my 18 foot twin axle trailer hitch.
Item has been installed for about a year and still going strong
this isn't so much about the spring, but the ability to get a small part to repair a larger part of a trailer and save hundreds of dollars. I thought I was going to have to buy a complete new hitch, instead, I was able to get this minor and inexpensive part and repair my hitch.

Great service and items are exactly what I needed
Easy to install and works great
Bought a used trailer where the coupler would not open on its own. The original spring was old and shortened over time. Glad I found e-trailer
Fast shipping. Excellent communication!

Still a smidge too small. I have decided to just leave it out and live without it.
