Rated 4 out of 5 by from 11 mm allen is a pain bought it for my 2013 fatboy after doing cams as an extra precaution. it did drop my temp down 10-15 degrees. One thing I hate about it is using the high epoxy to hold on the trim peace. Im waiting for the day it falls off. the 11 mm allen is kind of a p.i.a all in all still a good investment.

Rated 4 out of 5 by from Acceptable but not great With 10 being the best: (Quality 9), (Looks 8), (Price Point 4) (Usefulness 6). Needs special adhesive to hold cover on radiator $15.00....Needs odd size allen wrench to install (11mm....Had to buy a set which I'll never use again) $35.00. As one might expect, it needs air over it to be of any use, about 35 mph +. It does not do a very good job of lowering the oil temp once it gets to say 240f, but it will keep it around 210-230f if you stay off the throttle and keep moving. S&S breather, drilled stock pipes.

Rated 5 out of 5 by from Mandatory for Phoenix Daily Ride Keeps oil temperature several degrees lower. I think it is mandatory for Phoenix, but it is a good idea wherever the weather is warm. Install was straightforward. Tip: Don’t tighten up the clamps (fork and hose) until you have it put together. This made it easier to get the position of the cooler just right so the hoses allow easy filter access.

Rated 5 out of 5 by from A little added protection... After changing the pistons to 10.5:1 and installing larger cams I figured a little added protection for the engine would be a good idea. Just like with the engine - as long as there is air flowing into it then it is doing it's job and dropping the temp of the oil. If you're stuck in traffic going nowhere for a long period of time - turn off the bike until you get going... I would have preferred one that is more center mounted however with the ABS control on my HD this is not an option. It's not that noticeable on the side and helps save my investment.

For a 2016 heritage softtail, does it fit with the soft lowers installed on the engine crash bars?

Asked by: Skurtenb

More that one oil cooler that fit softtails

what is the difference between 26157-11A and 26157-07 and why doesn't it show both when searching for 2012 Fatboy Lo
Asked by: Shadow57
Hi Shadow57, Besides the differences in the fitment statements for each kit, P/N 26157-07A is center mounted, and 26157-11A is side mounted. Both kits are shown when breaking the down search for a 2012 FLSTFB by For The Bike - Custom Accessories & Trim - Engine & Mid Frame. Thank you for your question.

How much does this cool engine? Degrees?

Asked by: Wnsor
Hi Wnsor, It has potential to cool oil by approximately 20+ degress, but a number of factors can affect the results. Such variances may be ambient temperature, speed of bike, humidity and so forth. Hope this helps!

how many deegres does the cooler drops

hello, how many deegres it cools the oil? is there a way to put is in the center of the bars? i have ABS. thanks
Asked by: FranciscoG
A lot of variables to determine actual temperature change - HD claims about 20 degrees. As for the center mounting - no. Not with ABS and the hoses and clamps that are included. If you get really creative there might be a way but it will reduce the oil temp greater in it's recommended position.
