Jims USA Forceflow Cylinder Head Cooler


Smooth, streamlined design will keep your Twin Cam running cooler on those hot summer days in stop and go traffic. Jims R&D department has come up with a serious way to drop your head temperature by as much as 100 degrees! Although this mounts in the horn location, JIMS has relocated a horn inside the fan housing for a clean installation that doesn't sacrifice function. The fan itself can be configured for manual or thermostat-controlled on/off functionality. The thermostat switching configuration monitors cylinder head temperature and activates the fan when engine temperature reaches 140 degree.

Highly recommended for performance Harley-Davidson motors, this kit will help extend engine life and increase running reliability, regardless of where or how you ride. Each kit includes a high-powered fan, fan housing, horn, hardware and all wiring, along with detailed installation instructions.

  • Perfect solution for those hot running Twin Cam Touring bikes
  • Consistently reduces operating temperatures by up to 100 degrees
  • High-tech, waterproof cooling fan pushes air around cylinders and cylinder heads
  • Includes built-in quality OEM-type replacement horn
  • Easy plug-and-play installation with no drilling
  • 110" motors require optional adapter mount (sold separately)
  • Made in the USA

Jims force flow cylinder head cooler kit #5468

By   on  Verified Purchaser

Have 2017 road glide ultra with a 128 big bore kit with DK custom oil filter relocation kit and oil cooler installed than added this Jims force flow cylinder head cooler kit. Seems to work as advertised. Directions could have better pics. Wish it had a little longer wire harness to reach that white plastic connector up into hide in wiring trough. A very tight fit putting gas tank back on trying to not crush wires too badly.

Fairly easy to install. The included coil relocation kit made this the best deal by far.


A very well-built and good-looking product.

By   on  Verified Purchaser

This thing looks really great when installed it's right in with the engine itself. Does not look too cluttered when installed. The horn is part of the unit itself. Follow the instructions included and read several times to familiarize yourself with the instructions. It makes the installation much easier. This is a plug and play item. You'll be happy with it.
