Buying Guide and FAQs

Buying Guide: Factors to Consider When Choosing Harley Bike Engine Oil Coolers

  • Compatibility: Ensure the cooler fits your Harley's model (e.g., Sportster, Softail, Dyna, Touring, Big Twin) and specifics like S&S 111/124/143 engines or frame tube diameters (1"–1-1/4"). Use the vehicle selector for year-specific matches to avoid mounting or flow issues.
  • Type of Use: For standard street riding, opt for universal kits without gauges; high-heat or performance conditions benefit from model-specific coolers with dual fans and thermal switches for automatic cooling in demanding environments.
  • Components and Upgrades: Select kits with heat exchangers, turbulators, AN #6 fittings, adapters, and dual fans (220 CFM); upgrade to gloss black or flat black finishes for style. Focus on waterproof IP68-rated fans and thermal switches for reliable operation.
  • Brand and Quality: Choose Pro-One for universal billet aluminum kits or UltraCool for model-specific options with aluminum heat exchangers. Prioritize durable, high-efficiency designs that lower oil temps up to 50°F for engine longevity.
  • Installation and Cost: Most kits include clamps, reducers, adapters, and hardware for frame tube mounting; prices range from $307.95 for universal to $589.99 for premium with fans—factor in same-day shipping and free shipping over $99 for value.

Frequently Asked Questions (FAQs)

  1. What Harley models do these engine oil coolers support? Coolers support Sportster, Softail, Dyna, Touring, Big Twin, and some S&S engines—use the year/make/model filter for exact compatibility, including side/down tube or below-regulator mounting.
  2. How do oil coolers improve engine performance? They lower oil temperatures up to 50°F via turbulators and dual fans, extending engine life and preventing overheating in hot conditions.
  3. What is typically included in an oil cooler kit? Kits include heat exchangers, fans, thermal switches, adapters, clamps, reducers, and hardware—check details for gauges or specific finishes.
  4. Are these coolers automatic? Yes, with thermal switches activating fans at 210°F for hands-free cooling.
  5. What if a cooler doesn't fit my Harley? Verify frame tube diameter (1"–1-1/4") and mounting position before buying. Our returns policy allows exchanges or refunds if it doesn't match.
  6. Can I find related engine parts? Yes—explore oil pumps, filters, or gaskets in the Harley engine category to complement your oil cooler upgrade for better cooling efficiency.

Big Power, Nice Sound!

Picked up a Pro Circuit pipe and silencer for my YZ125 it’s a game changer. The power feels way better and the sound is awesome.
