 Superior Quality, Style & Performance

 Cooler oil makes engines last longer!  The turbulators in each oil passageway gently stir oil, exposing it to more critical heat dissipation surface area for superior cooling with minimal oil pressure restriction.

 

At DK Custom Products we use Jagg Oil Coolers on our own Bikes, and are happy to make them available to our Customers. 
 

  • The cooler mounts to the left frame down-tube, spaced away from the frame to allow airflow to both the oil cooler and engine's cylinder.
  • The cooler is mounted to the frame using unique, highly-durable, Uralite mounts which have a shock-absorbing effect and clean styling.
  • The Slimline Oil Cooler's, six-tube, two-pass design offers three-times the cooling surface than our closest competitor. Special in-line turbulators add to the cooler's efficiency with minimal oil pressure loss or restriction.
  • Aluminum construction with durable powder coated finish. The Slimline is a High Performance oil radiator with smooth end caps that blend into the frame for a Stealth Look.
  • Jagg's unique thermostatically-controlled offset oil filter adapter provides an easy access point to the bike's oil supply for the installation of the oil cooler.
  • The Adapter is machined from two pieces of billet aluminum and installs between the bike's stock oil filter mount and the oil filter, and is designed with the same HyperFlow Technology as all Jagg components to ensure great performance as well as great flow characteristics.
  • The Slimline Oil Cooler Kit is supplied complete with all necessary hardware and detailed, easy-to-follow instructions.
  • Upgrade to a Braided Hose with Color Matched Hose Separators and Hose Finishers.  Available in Bright Stainless Steel Braid or Black Lightweight Fiber Braid.  Click HERE for full details on the Braided Hose options, or look at pictures above.

 

 

Fitment:  The Slimline Oil Cooler System was designed especially for Harley-Davidson Motorcycles, but will also fit any motorcycle with vertical frame tubes.

This system has an automatic By-Pass Valve already built into the oil filter adapter, but if you would like to Manually cut your Oil Cooler on or off you can choose to add the Manual By-Pass Valve in the options above. See the Manual By-Pass Valve HERE.

Why Do We Use & Recommend Jagg Oil Coolers?

HyperFlow Technology is the engineered balance between performance and flow. It should first be described as a "systems" way of thinking.

Air flow, fins, oil flow, turbulators, brazing technology, metal finish, oil filter adapter design, thermostatic actuator, etc., are each components maximized to contribute to the overall system. It is only when each individual component is considered in relation to its contribution to the whole that a true systems approach can be claimed.

 

Frequently Asked Questions:

At what temperature does the automatic thermostatic by-pass operate?

The actuator begins to move at 185ºF. By 195ºF it is fully-actuated, plugging the by-pass hole, and directing 100 percent of the oil's flow to the oil cooler.

Which direction does oil flow in these oil coolers?

There is no "In" or "Out" on Jagg oil coolers. Whichever port the oil enters, it exits the other one.

Why do I need an oil filter adapter?

Oil filter adapters provide an easy way to access the motorcycle's oil supply for the installation of an oil cooler. Jagg oil filter adapters direct oil through the filter first and then to the cooler. This is especially important on the pressure side of the engine. This allows the warmer, thinner oil to flow easily across the oil filter, and then on to the oil cooler, and then send clean, cool oil to the engine.

Cooling for longevity Review by JeffR
I purchased based on reviews and research. Adding more oil capacity to the system and cooling seems like a step in the right direction. I am also going to a reusable oil filter and an external breather system as well. Shipping was quick and the order was right. Great group to deal with. (Posted on 12/17/2020)

Great investment for a Cooler ride! Review by ABressler
I purchased this oil cooler kit for my 2008 Softail Night Train From DK Custom Products. I have an oil reservoir dipstick with a thermometer in it from HD. We were cruising Northern Arizona 2019 in August in >100°f weather, and my oil temperature read 258°f. Did my research, and having purchased from DK before, I purchased this kit. It has done Great! Keeps oil temperatures cooled to 200°f!!! (Posted on 12/31/2019)
