Three ways to mount an UltraCool
Pick your kit by where the cooler sits on the bike and how much of it you want to see. Every kit lists its fitment in the title.

Side Mount
Frame rail · shrouded · fanMounts on the front down tube with a shroud in gloss black or chrome and a thermostatically controlled fan. The most popular setup and the one to pick if you want the cooler to look like part of the bike.
Shop side mount →
Below Regulator
Hidden · fan-assistedTucks in under the voltage regulator where the stock cooler lives on Touring and Dyna. Same fan-forced cooling with less on show — gloss, flat black, chrome or stainless.
Shop below regulator →
Naked Black
No shroud · lower priceThe cooler without the shroud, in black. Tucks behind lowers or runs stripped down, and costs less than the shrouded kits.
Shop naked black →Why cool it and filter it?
Air-cooled V-twins run hot, especially in stop-and-go traffic and two-up on long days. Heat breaks down oil, and a paper filter only catches so much of what's left.
UltraCool oil cooler
Fan-forced coolingA thermostat switches the fan on when oil gets hot, so the cooler keeps working even when you're sitting at a light, not just at highway speed.
PC Racing FLO filter
Stainless · reusableA stainless micron screen instead of paper. Clean and reinstall it at every oil change rather than throwing one away, and see what it caught.
