I want to install an oil cooler on my 2003 Softail Fatboy while I have it torn down. I have researched the available oil coolers and I don't like what I have found so far. I like the look of the touring models with an oil cooler installed since the oil cooler is down below the voltage regulator. Is there a way to adapt a cooler or one that will mount like that on a Fatboy? I know Jagg sells a low mount oil cooler, but I dont like how it mounts. It just hangs down below the voltage regulator. It looks like once my bike is lowered it would be too risky of hitting an object and damaging it.

Ideas, comments, product suggestions are needed and very much appreciated.

Jagg sells a premium cooler with end caps to match the cylinder fins on the twin cam. I didn't like the low mount either so I opted for the downtube mounts. I did the dual installation with one cooler on each downtube. Works great, looks okay and keeps the temp around 180.

I put the Jagg Softail low mount on my lowered 03 Fatboy and it seems fine. The bottom of the cooler is still above the bottom of the frame. The mounting is pretty clean and the adapter doesn't leak. I suppose it could catch a rock off the front tire, but so far it is fine.

Could you guys post some pics of your bikes so you can see the oil coolers installed?

I used the verticle jagg cooler between the downtubes on my Fatboy, I also have a Linby guard on.
I did upgrade the lines to SS with chromie ends.
It looks fine.

Try looking at billet cool no hoses cool location and matches the heads www.billetcool.com/

Thanks for the suggestion, but I don't see that as a viable option for a real oil cooler. I think you would probably get the same type cooling from the over the filter fins you can buy. I could be wrong, but I don't think that product is worth what they are charging for it. Do you have one installed and can back up their claim of oil temp drops that are as significant as a Jag or Harley by Jag oil cooler?

Do you have the chrome cover on it or just black? Got a pic?

I left the cooler black , no chrome trim, as I did not want to draw attention to it. SS hoses are for reliability and it was just the right thing to do.

I checked with one shop when I was considering running the Jagg Low Mount and I can get 6 feet of braided line that I can measure out, cut, and then fit with ends so I can maintain all stainless steel braided lines on my bike. I have thought that would look cool. I am still deciding on a cooler. The more I look at pics with bikes that have one installed the better idea i will have of what I decide to go with.

I am anxious to see the low mount pics that are slated to be on this thread later. It is a toss up between it and the one that mounts center of the down tubes.

Ill post some pics tonight. The jagg premium actually looks good. matches the TC cylinders well and looks factory. They work well also.

Why, just for looks?
Just looking for some insight cause I dont have a problem with mine getting too hot and I live in Ga where the summers can reach temps of about 95 degrees and above.
I have thought about it in the past but to me it just seems like a waste of good coin.

Fatboy,

No pics for you, but I went with black Jagg mounted on the left downtube. Easy install. No problems with it at all.

I am in Tennessee and I get the same and sometimes higher temps easily each year, but that is not why I am adding a cooler onto my bike. I am adding a lot higher compression ratio, much larger cam, and larger displacement to my engine over the winter months. I would like the added cooling capabilities of an oil cooler to keep the temps down. A little more cooling over stock can't hurt. I am combining the cooling of the oil cooler along with some carbide, graphite, and ceramic impregnation coatings inside the engine. All that together should bring the temps down considerably.
