  Ultimate Heat Reduction Mods


Felt Heat & Engine Heat


If you're wanting to be more comfortable along with having better performance, simply reducing heat (both felt heat & engine heat) will get you there.  

Below are the things that, when combined, will get you the

ULTIMATE Dyna Heat Reduction




Felt Heat- 



Engine Heat-


Felt Heat Reduction



Highway Pegs



  • Get your boots/feet/legs away from the engine

  • Stretch out your legs


Simply having highway pegs gives you the ability to stretch your legs out and get them away from the engine heat and exhaust.





  • Get your boots/feet/legs further away from the engine & exhaust

  • Larger platform for adjusting


Much like highway pegs, floorboards give the rider more room to adjust with their larger platform and get their legs away from the engine heat and exhaust. 



Engine Heat Reduction



Gas Tank Lift



  • Allows more airflow around top of engine

  • Plus of less air coming up & around tank, hitting the rider

  • Plus of easier cleaning of top of engine


Lifting the tank up off of the engine will assist in cooling since less air will be coming up over the tank and will instead be flowing under the tank and around the top of the engine. This will also mean less air hitting the rider and easier cleaning of your motor! It’s a win-win!

Coil Relocation 



  • Unblocks air flow to rear cylinder

  • Puts coil out in the wind


With your coil relocated to the left side of the engine, airflow is no longer blocked to the rear cylinder and your coil is out in the wind. 

Oil Filter Relocation



  • Puts filter in the wind

  • Plus of mess-free oil changes


By relocating your oil filter, either mounting it on the downtube (Sportster, Dyna, & Softail) or tucked high and tight under the left side passenger floorboard, it’s now out in the wind and will help in cooling. Plus, there will be no more mess when it’s time to change your oil!


Permanent Oil Filter



  • Billet housing aids in lower oil temps

  • 7 times more oil flow than paper filters

  • Cleanable & Reusable


This is the last oil filter you will ever need to buy. Not only is it cleanable,  its billet housing fins help lower oil temps via heat dissipation. It also flows much more oil than standard paper filter and its integrated magnet prefilters the oil. 



Force Flow Fan



  • Lowers Head Temps Up to 100*
  • Doubles As a Horn

Excessive heat and operating temperature can be an engines worst enemy. The patent pending JIMS ForceFlow literally forces the heat away from your engine by pushing high velocity air through the cylinder fin pack in a wide flow pattern, directed at the head gasket surface.

This unique design also relocates the horn inside the ForceFlow’s streamlined housing, and gives the horn mount or “left side” of the bike a much needed new look. 



Oil Cooler

LowMount Oil Cooler System for Harley-Davidson Dyna Models DK Custom High Flow Performance Dyna Cooler Running Motor Jagg HD 10 row Black


It’s crucial to performance and engine longevity to cool down your oil.   At DK Custom Products we use Jagg Oil Coolers on our own Bikes, and are happy to make them available to our Customers. 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.


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.


Lowering the heat in the engine is one of the best ways to extract more power.  Click this LINK to see why optimum power is generated when the cylinder walls are 190*.
